372 Series 37211000001 Littelfuse Radial Fuse Time-Lag TR5

Configured for circuit protection, Littelfuse 37211000001 provides 1A time-lag protection at 250V AC in the TR5 radial format. The through-hole fuse uses radial leads, a compact Ø8.5 × 8mm maximum body, and published breaking capability of 35A @ 250VAC. Its melting integral at 10× rated current is 7.5 A²s for coordination work. Match the current, voltage and interrupting level to the protected circuit before installation. Compare speed, approvals and mounting details before treating another fuse as an equivalent.
