AJT25 – GOULD 25A 600V CLASS J TIME DELAY FUSE

A Class J time-delay fuse like the AJT25 is designed to carry temporary overload currents — such as motor start-up inrush — for a short period without blowing, while still providing fast, current-limiting protection under true short-circuit conditions. A fast-acting Class J fuse offers no intentional time delay and may blow on harmless inrush currents, making time-delay types the preferred choice for motor and transformer branch circuits.

Yes — Class J is a standardized UL/CSA fuse class, so the Gould AJT25 is dimensionally and electrically interchangeable with other manufacturers' Class J time-delay fuses of the same rating (25A, 600V), such as the Eaton/Bussmann LPJ-25SP or Mersen AJT25. Always verify the time-delay characteristic matches your application requirements before substituting.

Yes — the Gould AJT25 carries both UL and CSA certification, making it acceptable for use under the Canadian Electrical Code (CEC). It is rated 600V and 25A, covering the full voltage range common in Canadian single- and three-phase industrial systems. Always ensure the fuse rating matches the conductor size and equipment overcurrent protection requirements specified in your CEC installation.
