BUSSMANN 170M1420 Semiconductor Fuse

Manufacturer: BUSSMANN
Model / Part Number: 170M1420
Current Rating: 200 Amps (A) — This is the maximum amount of steady electrical current the fuse can handle safely without blowing.
Voltage Rating: 690 Volts (V) AC for international standards (IEC) and 700 Volts (V) AC for North American standards (UL).
Interrupting Rating: 200 kiloamps (kA) — This means it can safely stop a massive, sudden surge of up to 200,000 amps of electricity without exploding.
Class: aR — This tells us it is a high-speed, partial-range fuse meant specifically to protect semiconductors (the brainy chips inside large electronic systems).
Body Size: 000 (Square Body) — It has a small, square, ceramic body built to handle extreme heat.
Mounting Style: DIN 43653 — It features flat, bladed tags with slots on the ends, meaning it is screwed or bolted directly into place onto a mounting block.
Visual Indicator: It includes a built-in top status indicator. This acts like a tiny flag that changes or pops up to tell you visually if the fuse has blown and needs to be replaced.
