Bussmann 170M4561 Fuse

170M4561 Bussmann fuse is a high-speed, square‑body protective device rated for 350 A and up to 690 VAC IEC (700 VAC UL), designed for industrial power distribution and machine control. It interrupts fault currents quickly with an IR700-200kA interrupting rating at the rated voltage, enabling fast clearance of faults in feeders and switchgear. End connections are specified as 1GKN/50 AR UC, and the body measures 53 × 69 × 51 mm, enabling compact installation within Bussmann’s 170M family footprints. This model is commonly used to protect feeders, switchgear, and motor-control centers where rapid fault clearance is required and compatibility with IEC and UL standards is needed. Manufactured by Bussmann (Eaton), it reflects the 170M series’ focus on high-speed protection for industrial circuits with a 200 kA breaking capacity at 700 V class ratings.
