Leviton LB220-G – Frequently Asked Questions

1) What does GFPE protection on the Leviton 362577 breaker actually do, and is it the same as a GFCI receptacle?
Ground-fault protection of equipment is what the Leviton 362577 (LB220 series) provides: it trips on ground-fault current to protect equipment and wiring, combined with standard overcurrent interruption in the same 2-pole device. GFPE trips at equipment-protection levels, not the personnel-protection level a 5mA GFCI receptacle uses, so it is not a substitute for personnel protection on a 15 or 20 amp receptacle circuit. Use it where the concern is equipment and conductor damage from ground current on a branch circuit.
2) Is a 2-pole 20 amp breaker the right choice for a 240V piece of equipment, or do I need 3-pole?
Two poles covers single-phase 240V loads and multi-wire branch circuits, and the LB220 is rated 120 to 240 volts AC at 20 amps. A three-phase load needs a 3-pole device instead, and the LB220 is not one. For three-phase branch protection ZenSupply carries 3-pole molded case options including the ABB A2N Series and the ABB E150 Series.
3) What is the closest substitute for a Leviton 362577 breaker when the circuit is 3-pole instead of 2-pole?
The Leviton 362577 (LB220-G) is a 2-pole breaker, so a 3-pole circuit needs a different frame. Two 3-pole options are the ABB A2N Series molded case circuit breaker, which is UL listed, and the ABB E150 Series 3-pole thermal magnetic circuit breaker. Both carry three poles rather than the two the 362577 provides, and both use a molded case or thermal magnetic construction rather than the hydraulic magnetic trip of the LB220-G. If the panel schedule calls for equipment ground-fault protection, that is a function the 362577 carries and the two ABB frames are described as overcurrent devices only.
4) Can an ABB ST200M be used in place of a Leviton 362577 branch circuit breaker?
No. The ABB ST200M is a miniature circuit breaker built to UL1077, which is the standard for supplementary protectors, not for branch circuit protection. The Leviton 362577 is a branch circuit breaker with a 10 kiloamp short circuit current rating, intended for panelboards and load centers where branch circuit overcurrent protection is required. A UL1077 device is used downstream of a branch circuit device, so the ST200M does not replace the 362577 in a panelboard position. For a miniature breaker that is branch-rated, the Square D C60 is a UL489 miniature circuit breaker.
5) What should I use instead of a Leviton 362577 if the enclosure is DIN rail rather than a panelboard?
The Leviton 362577 is built for panelboards and load centers. For a DIN rail enclosure, the Square D C60 is a UL489 miniature circuit breaker with DIN rail mounting, and the Square D Multi9 C60 is a 1-pole C-curve miniature circuit breaker rated 120V AC. Both are miniature breaker formats rather than the hydraulic magnetic panelboard breaker the LB220-G uses, and the Multi9 C60 carries one pole against the two poles of the 362577, so a 2-pole DIN circuit needs two poles ganged or a 2-pole catalog number in that series.
6) What is the difference between the Leviton LB220-EP and LB220-G configurations?
Two configuration options are offered on the 20A 2-pole GFPE breaker: LB220-EP and LB220-G. The G configuration is the hydraulic magnetic trip version called out in the Leviton 362577 specification. Order by the full configuration suffix, since EP and G are separate part numbers and the panel or application determines which one you need.
7) Should I spec a hydraulic magnetic breaker or a thermal magnetic one?
Hydraulic magnetic, like the Leviton LB220, holds its trip curve regardless of ambient temperature, which is why it gets specified for hot or cold environments and for loads where a thermal breaker would derate. Thermal magnetic breakers are the general-purpose choice for conditioned panelboards and are what most distribution equipment ships with. ZenSupply carries thermal magnetic alternatives including the ABB E150 Series 3-pole and the Square D PowerPacT B, though those are overcurrent-only and do not provide the ground-fault equipment protection the LB220 adds.
8) Can I mount the Leviton LB220 breaker on DIN rail in a control panel?
The LB220 is a branch circuit breaker built for panelboards and load centers, not a DIN rail control-panel device. If you are populating a DIN rail in an industrial control enclosure, look at the Square D C60 UL489 miniature circuit breaker, which is specified for DIN rail mounting, or the ABB ST200M miniature breaker. Note those are overcurrent devices and do not include ground-fault equipment protection.
9) The Leviton 362577 is only 20 amps. What breaker handles a larger feeder?
The Leviton 362577 is a 20-amp branch circuit device. For larger feeder duty, molded case frames cover the step up: the Square D PowerPacT B is a thermal magnetic circuit breaker, and the Square D PowerPacT Q is an I-Line circuit breaker that bolts to an I-Line bus rather than seating in a branch panelboard position. On the ABB side, the A2N Series is a UL listed 3-pole molded case breaker and the XT4 Series is supplied as a 3-pole molded case kit. All of these are overcurrent frames; the equipment ground-fault protection built into the 362577 is a separate function that would have to be specified another way on a feeder device.
10) Is a thermal magnetic breaker interchangeable with the hydraulic magnetic Leviton 362577?
They trip on different principles and are not interchangeable by function even at the same rating. The Leviton 362577 (LB220-G) uses hydraulic magnetic trip, which holds its trip point across ambient temperature swings, and it is rated to an 85 degree Celsius operating temperature. Thermal magnetic frames such as the ABB E150 Series 3-pole and the Square D PowerPacT B use a thermal element whose response shifts with ambient heat. On a circuit sitting in a hot mechanical room or an outdoor enclosure, that difference is the reason a hydraulic magnetic breaker is specified in the first place, so confirm which the drawing calls for before swapping.
11) If I only need overcurrent protection and not ground-fault protection, what is a simpler alternative to the Leviton 362577?
The 362577 pairs overcurrent interruption with GFPE equipment ground-fault protection, which is what makes it the right device where a heat trace, pump, or similar load needs ground-fault sensing. Where the panel schedule calls for plain overcurrent protection only, straight breakers cover it: the Square D C60 UL489 miniature circuit breaker for DIN rail, the Square D Multi9 C60 1-pole C-curve at 120V AC, or the ABB E150 Series thermal magnetic frame for 3-pole work. Standardizing a facility on one or the other matters at replacement time, since a breaker without ground-fault sensing will not satisfy a circuit originally protected by a GFPE device.
12) What part number do I give my distributor for the Leviton 362577 GFPE breaker?
Leviton 362577 corresponds to the LB220 series, and you order it by configuration: LB220-EP or LB220-G. The G is the hydraulic magnetic 20A 2-pole build described under 362577. Give the full suffix, since the base LB220 number alone does not identify which one you want.
13) Where is the Leviton LB220 breaker manufactured?
Mexico is the country of origin for the Leviton LB220 breaker. That is the detail institutional and government buyers working under domestic-sourcing requirements usually need up front.
14) What is the difference between the Leviton LB220-EP and LB220-G, and does either cross to an ABB or Square D breaker directly?
LB220-EP and LB220-G are the two configuration options of the Leviton 362577, a 20-amp 2-pole GFPE breaker for 120-240V AC; LB220-EP carries UPC 078477814871 and LB220-G carries UPC 078477468609, and the G is the hydraulic magnetic GFPE configuration described in the series. Neither crosses one-for-one to the ABB or Square D frames, because those are different constructions and mountings: the ABB XT4 Series ships as a 3-pole molded case kit, the ABB ST200M is a UL1077 miniature device, and the Square D PowerPacT Q is an I-Line breaker. Order the Leviton by the LB220 configuration suffix rather than by a cross number.
