DiversiTech, 7-CRNR35, Dual Element Fuse, 35 A, 250 V, 200,000 A

Contractor-Grade Overcurrent Protection – DiversiTech® 7-CRNR35 RK5 Dual Element Time Delay Fuse

The DiversiTech® 7-CRNR35 is a dual-element time delay fuse designed to safeguard HVAC and motor-driven systems from short circuits and prolonged overloads. With a Class RK5 classification and a 200,000 A interrupting capacity, this fuse supports high fault current environments while minimizing nuisance tripping during inrush conditions.

Engineered for System Longevity and Compliance

This 35A, 250VAC-rated fuse is purpose-built for demanding electrical applications such as air conditioning and refrigeration systems, motor control circuits, and other inductive loads. The dual-element design delivers superior protection during motor startup while preserving system uptime.

Key Technical Advantages

• Amperage Rating: 35 A
• Voltage Rating: 250 VAC
• Interrupting Rating: 200,000 A RMS Symmetrical
• Construction: Dual element, time delay
• Class: RK5 per UL 248-12

Performance Features

• ✅ Dual Element Time Delay – Allows temporary overloads typical of motor startups without compromising protection.
• ✅ RK5 Certification – Meets the performance requirements for industrial fusing applications requiring short-circuit protection.
• ✅ High Interrupt Capacity – Rated for 200kA to safely isolate high fault currents.
• ✅ Consistent Arc-Quenching – Reduces potential damage to downstream components in fault scenarios.

Installation Considerations

Installation of the 7-CRNR35 should be completed by a qualified electrician or HVAC technician. Ensure compatibility with fuse holders rated for Class RK5 fuses and verify circuit parameters against nameplate data. Always de-energize equipment prior to replacement.

Contractor Use Cases

For licensed HVAC and electrical contractors: The 7-CRNR35 supports reliable operation across a range of motor-driven loads, with added protection during startup. It’s a cost-effective solution that reduces callbacks due to unnecessary tripping and minimizes equipment exposure to short circuit damage.

Compliance and Standards

• UL Listed: UL 248-12, Class RK5
• CSA Certified: CSA C22.2 No. 248.12

Professional Summary

The DiversiTech® 7-CRNR35 Dual Element Time Delay Fuse is an essential protective component for high-load HVAC and motor applications. It ensures coordinated circuit protection, minimizes service disruptions, and meets the demands of professional environments requiring robust overcurrent mitigation.
