A key feature of our three-pole fuse holders is their ultra compact design With a width of only 45 mm, they are ideal for use with fused motor starter combinations. Because the contactor and the fuse holder have the same 45 mm width, they are easy to mount on top of one another. The strong current-limiting fuses ensure a type 2 protection level (coordination according to IEC 60947-4, no damage protection) for the contactor.
The UL version has an SCCR value of 200 kA.
Compact fuse holder Class CC with signal detector and mounted auxiliary switch.
The accessories are generally UL-certified.
Customers can mount an auxiliary switch which signals the switching state or prevents the fuse holder from switching off under load by interrupting the contactor control, thus increasing safety for the operator and process.
Busbars and a matching three-phase feeder terminals complete the product range.
