Time Delay Dive Fuse, 250 V, 20A

DiversiTech 7-CRNR20 | 20A Dual Element Time Delay Fuse, 250V, Class RK5 The DiversiTech 7-CRNR20 is a 20-amp, 250 VAC dual-element time delay fuse designed to protect HVAC equipment and other inductive load applications from both short circuits and sustained overloads. This UL Class RK5 fuse is rated for interrupt currents up to 200,000 amps, making it suitable for use in commercial and industrial systems with high available fault current. The dual-element design accommodates initial motor inrush currents without nuisance tripping while providing dependable protection against prolonged overload conditions. It is frequently specified for compressor, motor, and control circuit protection in air conditioning, refrigeration, and heating applications. Features Time Delay Function – Allows safe passage of inrush current during motor start-up while protecting against overloads and faults Dual Element Construction – Offers both overload and short-circuit protection for inductive loads Interrupt Rating: 200,000 A RMS Sym. – Suitable for circuits with high fault current potential UL Listed, Class RK5 – Complies with recognized electrical safety standards Voltage Rating: 250 VAC – Compatible with common low-voltage electrical systems Technical Specifications Fuse Type: Dual element, time delay Amp Rating: 20 A Voltage Rating: 250 VAC Interrupt Rating: 200 kA RMS Symmetrical Class: RK5 Application: HVAC motors, compressors, control transformers, and branch circuits Installation Guidelines This fuse must be installed in properly rated fuse holders or fuse blocks and integrated into circuits in accordance with local codes and the NEC. Installation should be carried out by licensed electricians or qualified technicians to ensure proper protection and compliance.
