The ST 4-FSI/C range from Phoenix Contact are DIN rail, spring-cage terminal blocks that feature a C type fuse. This range of DIN rail, fused terminal blocks form a tight connection to your wire thanks to the spring-cage technology, it also means an effortless install! Simply push-in your wire. Not to mention, the fuse in this terminal block is a flat fuse and helps add another level of protection. DIN rails NS 35/7.5 and NS 35/15 are supported for the ST 4-FSI/C range of terminal blocks and the blocks have a nominal current of 30 A with a nominal voltage of 400 V.

The housing on these fused terminal blocks is made from a durable polyamide material and the contacts are copper with a plating. These devices accept 28-10 AWG and have a cross-section of 0.08 mm² - 6 mm².
