Bussmann 15188-3RS – Frequently Asked Questions

1) Will the Bussmann 15188-3RS mount on standard 35mm DIN rail in my control panel?
The 15188-3RS is a depluggable DIN rail terminal block with a locking snap mount, so it clips onto the rail and can be pulled off again without unwiring the whole run. Module center spacing is 0.375 in, which lines up with standard DIN terminal block layouts when you gang it alongside other blocks. Body size is 1.97 in high, 1.88 in wide and 1.57 in deep, so allow for that in your wireway clearance.
2) Can one Bussmann 15188-3RS disconnect all three phases of a 480V motor circuit?
Yes. It is a three-pole block, so all three legs break together from a single disconnect, and the 600V rating covers 480V three-phase work. Current is limited to 30A, so size the branch accordingly.
3) Is this Bussmann disconnect block a circuit breaker or a fuse holder?
Neither. The 15188-3RS is a disconnect-only terminal block: it isolates the circuit for service, it does not provide overcurrent protection. If you need protection on the same rail you have to add a fused block or breaker upstream.
4) What torque should I use on the terminal screws of the 15188-3RS?
Tighten the terminal screws to 12 lb-in. The hardware is a zinc-plated steel philslot screw, so it takes either a slotted or Phillips driver. Contacts are tin-plated copper alloy on a molded thermoplastic base.
5) Will a Bussmann 15188-3RS hold up in a hot, unconditioned panel enclosure?
It is rated to 105 degrees C operating temperature, which covers most industrial enclosures including ones running warm from drives or transformers. The thermoplastic base handles the insulation duty and the tin plating on the contacts adds corrosion resistance in humid plant environments.
6) Can I pull the 15188-3RS off the rail without disturbing the wiring?
That is the point of the depluggable design. The plug section separates from the wired base, and the locking snap holds it to the rail until you release it, so a panel builder can swap a module or test a circuit without landing conductors again.
7) What is the exact part number to order this Bussmann three-pole DIN disconnect block?
Order it as Bussmann 15188-3RS, from the Eaton series 15188 family. That single part number covers the three-pole, 600V, 30A depluggable block with the locking snap mount.
