Time Delay Dive Fuse, 250 V, 25A

DiversiTech 7-CRNR25 – 25A Dual Element Time Delay Fuse, Class RK5 The DiversiTech 7-CRNR25 is a 25-amp dual element, time delay fuse designed to protect HVAC systems and other motor-driven equipment from overcurrent conditions. Rated for 250 VAC and compliant with UL Class RK5 specifications, this fuse is built to manage high fault current scenarios while allowing temporary overloads typical during motor start-up. The dual element design enables delayed response under low-level overloads while providing fast short-circuit protection, minimizing nuisance tripping and preserving equipment integrity. Key Product Features Amperage Rating: 25 amps Voltage Rating: 250 VAC Interrupting Capacity: 200,000 amps Time Delay Function: Withstands motor start-up surges without nuisance tripping Class RK5: Meets UL 248-12 standards for industrial fuse performance Element Type: Dual-element fuse for extended motor protection Application and Use The 7-CRNR25 is commonly installed in HVAC disconnects, control panels, and motor branch circuits where temporary inrush protection is required. Suitable for indoor or protected environments, it is compatible with standard RK5 fuse holders. Installation Guidelines Installation should be performed by qualified personnel familiar with NEC requirements. Always verify fuse compatibility with both the system voltage and downstream equipment. This fuse is intended for systems that may experience periodic overloads or inrush currents and should not be substituted with fast-acting types unless specified.
