Time Delay Dive Fuse, 250 V, 45A

DiversiTech 7-CRNR45 – 45A Class RK5 Dual Element Time Delay Fuse The DiversiTech 7-CRNR45 is a 45-amp, 250V dual-element time delay fuse designed for overcurrent protection in HVAC and other inductive load applications. Classified as a UL-listed Class RK5 fuse, this component is suitable for safeguarding motors, transformers, and branch circuits from short circuits and overload conditions, especially where temporary current surges are expected during equipment startup. This fuse offers a time-delay characteristic that permits brief overcurrent conditions without nuisance tripping, allowing normal equipment operation while still providing protection during sustained faults. Its high interrupting capacity of 200,000 amps AC ensures safe performance in circuits subject to significant fault current. Specifications Amp Rating: 45 A Voltage Rating: 250 VAC Interrupting Rating: 200,000 A Fuse Type: Time Delay, Dual Element UL Classification: Class RK5 Application: HVAC systems, motor circuits, and general-purpose overcurrent protection Performance Features Dual-element construction enables both short-circuit and overload protection Time-delay functionality supports motor startup without fuse fatigue Rated for use in systems where high fault current protection is required Designed to reduce downtime and nuisance replacement from transient overloads Installation Considerations This fuse is intended for use in properly rated fuse holders or disconnect switches designed for Class RK5 fuses. Installation must follow NEC guidelines and local electrical codes. For safety and compliance, installation should be performed by qualified electrical or HVAC personnel. Use Case Appropriate for commercial HVAC systems, motor control centers, industrial panels, and similar installations where equipment is subject to initial inrush currents. Its time-delay response allows it to accommodate the operational characteristics of inductive loads while providing reliable protection during sustained overcurrent or fault events.
