1sna167079r0100 – fuse 8a

Why Choose the TE Connectivity 1SNA167079R0100 FU103-8A Fuse?

The TE Connectivity 1SNA167079R0100, also designated FU103-8A, is an industrial 8 A cartridge fuse designed for circuit protection within electrical control panels, automation systems and compatible SNA fuse terminal assemblies. Part of the established TE Connectivity / Entrelec terminal block accessory range, it provides a compact and replaceable means of protecting electrical circuits against excessive current.

This fuse uses the widely adopted 10.3 × 38 mm cylindrical cartridge format, making it suitable for compatible fuse terminals and holders designed around this size. Its compact dimensions help panel builders incorporate circuit protection into space-conscious industrial control and distribution assemblies while retaining straightforward fuse replacement during maintenance.

With a rated current of 8 A and a voltage rating of 500 V, the FU103-8A is suitable for industrial electrical applications requiring dependable cartridge-fuse protection. It is specifically listed for use with compatible MB10/22.SF and MB10/24.SF fuse terminal blocks.
