170M5013 EATON BUSMANN FUSE
170M5013 EATON BUSMANN FUSE – High-Speed 700A 690V/700V Size 2 Square Body Fuse
The 170M5013 EATON BUSMANN FUSE (Model 170M5013) is an industrial-grade, ultra-fast square body semiconductor protection fuse manufactured by Eaton’s Bussmann series. Engineered specifically for heavy-duty power conversion and industrial automation equipment, this 700 -amp Class aR high-speed fuse provides fast, reliable protection for sensitive power semiconductors, including thyristors, diodes, silicon-controlled rectifiers (SCRs), and IGBT switches.
Designed with a dual voltage rating of 690 VAC (IEC) and 700 VAC (UL), alongside a high short-circuit interrupting rating of 200kA RMS Symmetrical, the 170M5013 EATON BUSMANN FUSE clears severe fault currents in milliseconds. Built in a DIN 43653 Size 2 square body form factor with slotted blade terminals (type 2/110), it features a low cold resistance of 0.1195 m Omega at 21°C to minimize power loss (I^2t) and reduce internal heat buildup inside control cabinets and power enclosures.
As shown in the image, the fuse features a white ceramic square body clearly printed with “EATON BUSSMANN 170M5013 700A 690V~IEC 700V~ aR 2/110 0.1195 mΩ(21°C)”, fitted with a top visual trip indicator pin and slotted blade terminals for secure busbar installation.

Operating Guidelines and Usage Tips
SAFETY NOTICE: Always isolate power supplies and verify circuits are fully de-energized using a calibrated voltage meter before replacing high-power semiconductor fuses.
Torque Specifications: Torque all connection bolts to the manufacturer’s specified limits to ensure low contact resistance and eliminate localized hot spots.
Application Precaution: High-speed Class aR fuses are designed exclusively for short-circuit protection of power electronics and must be paired with dedicated overload protection devices for full-spectrum circuit safety.
To review official IEC high-speed square body fuse standards and industrial power protection criteria, consult the International Electrotechnical Commission (IEC) Portal.
