1sna008291r0000 – cartridge fuse 5×20 2a

Why Choose the TE Connectivity 1SNA008291R0000 Cartridge Fuse?

The TE Connectivity 1SNA008291R0000, also identified as FU520/2A, is a compact 5 × 20 mm cartridge fuse designed to provide dependable overcurrent protection in industrial electrical and control circuits. Part of the established Entrelec SNA terminal block accessory range, this fuse is particularly suited to compatible fuse terminal blocks used in control panels, machinery and automation systems.

With a rated current of 2 A and a rated voltage of 250 V, the FU520 fuse provides replaceable circuit protection for compatible Entrelec fuse holders and terminal blocks. When excessive current flows through the protected circuit, the fuse element operates to interrupt the current, helping protect wiring and connected equipment against potentially damaging overcurrent conditions.

The standard 5 × 20 mm format makes the 1SNA008291R0000 suitable for compatible Entrelec SNA fuse terminal products, including fuse terminals designed to accept FU520 cartridges. Its compact dimensions and straightforward replacement make it a practical protection component for industrial control cabinets and electrical distribution assemblies.

Reliable Overcurrent Protection for Industrial Circuits

Cartridge fuses provide a straightforward method of protecting electrical circuits against excessive current. When current exceeds the fuse's operating characteristics, the internal fuse element opens the circuit, helping prevent sustained overcurrent from damaging conductors, terminal equipment and other connected components.

The TE Connectivity FU520/2A combines a 2 A current rating and 250 V voltage rating with the widely used 5 × 20 mm cartridge format. It is intended for compatible Entrelec fuse terminal blocks, providing a replaceable protection element within modular industrial wiring systems.
