Mersen SBS5 – Frequently Asked Questions

1) Will the Mersen SBS5 fit a standard 13/32 x 1-1/2 inch midget fuse holder?
The SBS5 is a midget-class fuse with a body length of 1.38 in and ferrule terminals, clip mounted. That is the standard midget footprint used in panel fuse blocks and clip-style holders, so it drops into holders built for midget ferrule fuses. It is not a rejection-style Class CC fuse, so it will also sit in a non-rejecting midget clip.
2) Can I use the Mersen SBS5 on a 480V or 600V control circuit?
Yes. The SBS5 is rated 600 V AC (UL) at 50/60 Hz, so it covers 120V, 240V, 480V and 600V AC control and distribution circuits. It is an AC-rated device, so do not specify it for a DC application.
3) Is a 100 kA interrupting rating enough for my industrial panel's available fault current?
The SBS5 carries a 100 kA AC breaking capacity, which covers the short circuit current rating most industrial control panels and motor control centers are built to. If your engineered fault study shows available fault current at or below 100 kA at the fuse location, this fuse is adequate for the interrupting duty.
4) Should I use a fast-acting fuse like the SBS5 or a time-delay fuse on my circuit?
Fast-acting is the right choice when the load has little or no inrush: control transformers on the secondary side, instrumentation, electronics, lighting control and general feeder taps. The SBS5 clears quickly to protect downstream wiring and equipment. If you are protecting a motor or anything with a heavy starting surge, a fast-acting fuse will nuisance-open, and you want a time-delay type instead, such as the Littelfuse CCMR Series Class CC time-delay fuse.
5) Is the Littelfuse BLF midget fast-acting fuse a drop-in replacement for the Mersen SBS5?
Both are midget-class fast-acting fuses, but the voltage ratings differ. The Mersen SBS5 is rated 600 V AC, while the Littelfuse BLF series is a 250 V midget fast-acting fuse with a laminated tube body. If the circuit is a 600 V control or distribution circuit, the SBS5 carries the rating; the BLF suits 250 V work. Check the holder or clip spacing against the SBS5 body length of 1.38 in before swapping either way.
6) My motor starter keeps blowing the SBS5 on inrush. What should I use instead?
A fast-acting fuse like the Mersen SBS5 opens quickly on any overcurrent, including motor inrush, which is why it is better suited to control and instrumentation circuits than to motor branch circuits. For motor loads, a time-delay fuse rides through starting current: the Littelfuse CCMR series is a Class CC time-delay fuse, offered for example as the CCMR040 at 40 A. Size the time-delay fuse to the motor nameplate and confirm the holder accepts a Class CC rejection body, which differs from a plain midget clip mount.
7) What amp rating and part number do I order for a 5 amp 600V midget fast-acting fuse from Mersen?
Order Mersen part number SBS5. The ampere rating is 5 A at 600 V AC, fast-acting, midget class, with ferrule ends for clip mounting. Each fuse weighs 0.016 lb, so a full panel's worth ships light.
8) I need 0.5A metering fuses, not 5A. Is the SBS5 the wrong part?
Yes, the SBS5 is a 5 A device and will not give you the protection level a meter CT or voltage input circuit needs. For metering, look at the Square D PowerLogic Energy Meter Fuse Pack, a set of three rated 0.5A at 600V.
9) I need 600V fuses for a metering circuit - SBS5 or the Square D PowerLogic fuse pack?
The Square D PowerLogic energy meter fuse pack is a matched set of three 0.5 A 600 V fuses intended for metering voltage taps, where the 0.5 A rating suits the very small burden of a meter input. The Mersen SBS5 is a single 5 A 600 V AC midget fast-acting fuse, a better fit for control and equipment circuits that draw more than a meter input does. Both carry 600 V; choose on the ampere rating the circuit calls for.
10) Will the SBS5 terminals hold up in a humid or corrosive panel environment?
The ferrule ends are tin-plated copper, which resists oxidation at the clip contact and keeps contact resistance down over time. The body is GMG insulating material. That combination is intended for continuous service in industrial control enclosures rather than clean-room-only duty.
11) Is the Mersen SBS5 RoHS compliant for a spec that requires it?
Yes, the SBS5 is RoHS compliant, so it clears procurement specs and institutional purchasing rules that require RoHS on electrical components.
