Bussmann 40K07C Low-Voltage HRC Fuse 40A 600V AC Class C

The Bussmann 40K07C is a high-rupturing capacity (HRC) fuse from the HRCII-C series, designed for low-voltage electrical protection in industrial and commercial settings. Rated at 40 amperes and 600 volts AC, this Class C fuse provides reliable overcurrent and short-circuit protection, complying with Canadian standards (CSA C22.2). It features a robust ceramic body with silver-plated copper blade terminals for secure mounting in compatible fuse holders. Key applications include motor control circuits, transformer protection, and distribution panels where high fault currents are possible. Benefits include an interrupting rating of up to 200,000 amps, current-limiting design that reduces equipment damage and arc flash risks, and high durability in harsh environments. Compared to standard cartridge fuses, the HRC design offers superior performance in high-fault scenarios, though it may require specific holders and comes at a higher cost. Drawbacks include single-use nature after blowing and potential incompatibility with non-HRC systems. Based on attached images, the fuse appears new or unused, with clean labels showing model 40K07C, 600V AC, Class C, and no visible wear or damage. No serial number is evident, and there are no attached parent/child assets like holders or indicators.
