Bryant 30103D – Frequently Asked Questions

1) Will the Bryant 103D disconnect switch work on a 480V three-phase motor circuit?
Yes. The Bryant 103D Series manual disconnect is rated 600V, so it covers the common 208V, 240V and 480V three-phase systems. Its 3-pole build switches all three ungrounded conductors at once, which is what you need for complete isolation on a three-phase feeder or motor circuit.
2) What is the difference between the Bryant 30103D and the 40003D?
Both are the same 600V 3-pole manual disconnect; the difference is the motor full-load-amp rating. Order 30103D for a 30A motor FLA and 40003D for 40A. Size it against the nameplate FLA of the motor you are isolating, not the breaker size.
3) Does the Bryant 103D include fuses or overcurrent protection?
No. The 103D Series is a non-fused manual disconnect switch, so it isolates the circuit but provides no overcurrent protection on its own. If you need fusing built into the disconnect, a fusible unit such as the Square D TeSys GS 3-pole 30A 600V fuse disconnect switch is the type to look at instead.
4) What is the closest equivalent to the Bryant 30103D if I need fusing built into the disconnect?
The Bryant 30103D is a 3-pole manual disconnect switch rated 600V, sized by Motor FLA at 30A and 40A. It switches the three phases but does not carry fuses. If the circuit needs overcurrent protection at the same device, the Square D TeSys GS1DU3 is a fuse disconnect switch, 3-pole, 30A, 600V, so it matches the pole count and voltage class while adding fuse holders in the same enclosure position. Choose the Bryant where upstream fusing or breaker protection already exists and you only need a service isolation point.
5) Can this Bryant disconnect be locked out for maintenance?
Yes, the 103D Series is a manual disconnect that gives a visible, lockable point of isolation for de-energizing a circuit during service or inspection, so it can be used as the local service disconnect at a motor or piece of equipment.
6) I need a rotary handle disconnect that mounts through an enclosure door. Is this the right one?
The Bryant 103D is a manual disconnect switch without a door-mounted rotary operator. For a through-the-door rotary handle arrangement, the Square D TeSys VLS protruding rotary handle disconnect switch with the 65 x 65 mm handle is the style to specify.
7) Is a 40A disconnect enough for a 40A motor, or should I go larger?
The 40003D is rated at 40A motor FLA, which means it is matched to a motor drawing up to 40 amps full load. Compare it to the motor nameplate FLA. If the nameplate is above 40A, neither the 30A nor the 40A version in the 103D Series covers it and you need a higher-amperage disconnect.
8) I need a disconnect operated from outside the enclosure door. Is the Bryant 103D the right choice?
The Bryant 103D Series, models 30103D and 40003D, is a manual disconnect switch providing a lockable point of isolation for three-phase 600V circuits. If the requirement is a door-mounted operator the electrician turns from the front of the panel, the Square D TeSys VLSH2S5B is a protruding rotary handle disconnect switch with a 65 x 65 mm handle, which is the format used when the handle must break the enclosure face. Specify the Bryant when the switch sits inside the assembly or in its own housing and the rotary handle format is not required.
9) Where is the Bryant 103D switch typically used in a building's power distribution?
Typical placements are panelboard and switchgear isolation points, three-phase motor and equipment branch circuits, and service disconnects for maintenance, in both new construction and retrofit work. It is a commercial and industrial distribution device rather than a residential wall switch.
