A4J35 – GOULD 35A 600V FAST ACTING FUSE

The A4J35 is a Class J fuse and must be installed in a Class J-rated fuse holder or fuse block. Class J holders feature rejection clips that prevent installation of non-Class J fuses, ensuring the correct interrupting rating is maintained. Common compatible holders are available from Gould/Ferraz Shawmut, Eaton/Bussmann, and Littelfuse. Contact our team if you need help sourcing the right holder.

The Gould A4J35 cross-references directly to the Bussmann LPJ-35 and the Littelfuse KLDR-35 — both are 35A, 600V, 200kA Class J fast-acting fuses with the same form and function. Northern Breaker Group specialises in obsolete and hard-to-find fuses, so if the original Gould part is what you need, reach out to us for availability.

Yes. The A4J35's fast-acting characteristic and 200kA interrupting rating make it suitable for motor branch-circuit and control-circuit protection where fast response is specified. It meets the high interrupting capacity requirements outlined in the Canadian Electrical Code (CEC). However, for motor running overload protection, ensure your circuit design also includes an appropriately sized overload relay, as a fast-acting fuse alone does not provide running overload protection.
