Bussmann 170M6118 Eaton Series High-Speed Square Body Fuse, 1500A, 700V, Class aR

Bussmann 170M6118 Eaton Series High-Speed Square Body Fuse, 1500A, 700V, Class aR

The Bussmann 170M6118 is an Eaton series high-speed square body fuse engineered for precision overcurrent protection in demanding power electronics applications. Rated 700V (UL) and 690V (IEC) with a 1500A amperage rating and a 200 kAIC interrupt rating, this Class aR fuse is designed for accompanied semiconductor protection. The blade end X blade end square body design conforms to the DIN 43 620 mounting standard for compatibility with standard high-speed fuse holders and disconnects used in industrial power conversion equipment.

Key Features

• Amperage Rating: 1500A supports high-current semiconductor protection circuits.
• Voltage Rating: Dual-rated 700V (UL) / 690V (IEC) for use across both UL and IEC-compliant electrical systems.
• Interrupt Rating: 200 kAIC interrupt rating delivers robust short-circuit protection in high-fault-current environments.
• Utilization Category: Class aR (accompanied semiconductor protection) is purpose-built to protect thyristors, diodes, and other power semiconductors from short-circuit currents.
• Fuse Shape: Square body construction with slotted, center-bolted tags in a blade end X blade end configuration per DIN 43 620.
• Clearing Performance: Pre-arc I²t of 460000 and clearing I²t of 3100000 at 660V provide fast, predictable current limitation.
• Compact Dimensions: Measures 168 mm (length/depth) x 95 mm (width) x 76 mm (height) at 940 g for straightforward integration into fuse holder assemblies.
