DiversiTech 7-CRNR35 | 35A Dual Element Time-Delay Fuse, Class RK5, 250V
The DiversiTech 7-CRNR35 is a 35-amp, 250-volt, dual-element time-delay fuse designed for HVAC motor and compressor circuit protection. Built to U.L. Class RK5 standards, it combines overload tolerance with short-circuit protection, making it well-suited for inductive load applications where motor inrush currents can cause nuisance tripping in fast-acting fuses.
This fuse features a dual-element construction, allowing it to carry temporary overloads while still opening on sustained faults. With a 200,000 amp interrupting capacity, it is rated for high fault environments and is compatible with systems requiring Class RK5 performance. It is intended for use in fused disconnects and control panels servicing heating and cooling equipment.
