Bussmann 15188-4 – Frequently Asked Questions

1) Will the Bussmann 15188-4 terminal block mount on standard 35 mm DIN rail in my control panel?
Yes. The 15188-4 mounts to standard 35 mm DIN rail using a C-rail profile, and the depluggable body lifts off the base so you can pull a pole without disturbing the wiring. Plan panel space around 1.97 in height, 1.88 in width and 1.57 in length/depth.
2) Can I use the Bussmann 15188-4 on a 480V three-phase circuit?
The 15188-4 is rated 600V and 30A, so a 480V three-phase feed is inside its voltage rating as long as the load current stays at or below 30A. With four poles you can switch three phases plus a neutral or a fourth circuit at the same time.
3) Is this a circuit breaker or just a disconnect terminal block?
It is a disconnect, not overcurrent protection. The 15188-4 isolates the circuit so you can safely service downstream equipment, but it does not trip on overload or fault. You still need a fuse or breaker upstream sized for the circuit; the block itself tops out at 30A.
4) What torque should the screw terminals on the Bussmann 15188-4 be tightened to?
Tighten the #6-32 TPI screw terminals to 12 lb-in. That is the rated torque, and hitting it is what keeps the connection low resistance and vibration resistant on a machine panel. Use a torque screwdriver rather than feel, since under-torqued terminals are the usual cause of heating at a block like this.
5) Is the Bussmann 15188-4 disconnect block rated for a hot enclosure?
It carries a 105 degree C operating temperature rating, which covers most sealed industrial enclosures and drive panels that run warm. Contacts are tin-plated copper alloy, so corrosion resistance holds up in those conditions too.
6) How do I order the right Bussmann 15188 block for a four-circuit disconnect?
Part number 15188-4 is the four-pole version of the Eaton 15188 series. The dash number is the pole count, so ordering -4 gets you four poles switching together in one white housing on a single DIN rail footprint.
