372 Series 37204000431 Littelfuse Radial Fuse Time-Lag TR5

For rated-current coordination, Littelfuse 37204000431 provides 0.4A 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 1.408 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.
