For replacement and selection work, Littelfuse 37203150411 provides 0.315A time-lag protection at 250V AC in the TR5 radial format. The through-hole fuse uses short radial leads, a compact Ø8.5 × 8mm maximum body, and published breaking capability of 35A @ 250VAC; 50A @ 125VDC. Its melting integral at 10× rated current is 0.3969 A²s for coordination work. Confirm the exact package suffix and electrical ratings when replacing an existing fuse. Selection should account for steady current and fault-energy demands rather than current rating alone.
