Bussmann by Eaton 170M5213 Medium Voltage Fuse

The Bussmann by Eaton 170M5213 is a high‑speed, square‑body medium‑voltage fuse designed for heavy current protection in IEC/DIN systems, rated at 700 A and 690 V AC. This 170M‑series device is a two‑terminal DIN‑2 cartridge with centered terminal connections and a compact 61 × 75 × 138 mm form factor, featuring a T‑style indicator for a micro‑switch and a robust square housing. It provides a rated interrupting capacity of up to 200 kA (DIN 43653, IEC 60269‑4) and is specified for semiconductor protection in MV power electronics and drive circuits, where fast fault interruption is crucial. The 170M5213 designation corresponds to the 2TN/110 AR UC variant, aligning with standard mounting and termination schemes used in industrial MV protection schemes. With its IEC‑compliant construction and precise current rating of 700 A, this fuse is suited for protecting high‑current components in medium‑voltage power distribution, motor drives, and semiconductor loads, delivering reliable protection without unnecessary nuisance operations.
