Bussmann 170M4561 Fuses Class 1GKN 350A 660V Rated

The Bussmann 170M4561 is a high-speed, 350 A, 660 V Class 1GKN fuse (square-body, size 1) from the 170M series, engineered to interrupt fault currents quickly in low‑voltage power circuits. This 53 × 69 × 51 mm device features a 1GKN indicator configuration (Type K) for micro‑fuse visibility and carries UL and IEC approvals for use in industrial equipment. With its fast-acting design, it is suitable for protection across control panels, motor drives, power supplies, and distribution systems where reliable overcurrent protection at up to 660 V is required. The 170M4561’s 350 A rating places it among the higher-current members of the 170M family, delivering rapid arc-quenching performance in demanding protection applications.
