CFD63B070L - 70Amp Circuit Breaker

CFD63B070L - 70Amp Circuit Breaker

When you're keeping a commercial or industrial electrical system operating as intended, using the correct replacement circuit breaker matters. The CFD63B070L is a 70 amp, 3-pole molded case circuit breaker from the CFD6 series, designed for use in three-phase power distribution systems where matching the original equipment specifications is important. Built on a Sentron frame and equipped with a non-interchangeable trip unit, this breaker is commonly used in existing installations where maintaining the original electrical ratings and configuration is a key part of the job.

The CFD63B070L combines a compact footprint with substantial interrupting capacity, making it a common choice for applications where available fault current is a consideration. With interrupting ratings of 200kA at both 240VAC and 480VAC, and 100kA at 600VAC, it is often found in switchboards, panelboards, motor control equipment, HVAC systems, and other power distribution applications. Its fuseless current-limiting design helps support the protection requirements of compatible electrical systems while maintaining the characteristics expected in CFD6 installations.

Designed for operation at 50/60Hz and rated for ambient temperatures up to 40°C, the CFD63B070L is HACR rated for heating, air conditioning, and refrigeration applications. Load-side terminals are included to help simplify installation in compatible equipment. Built to last, this breaker is commonly used in manufacturing facilities, warehouses, commercial buildings, schools, healthcare facilities, and other locations that rely on three-phase electrical distribution. For maintenance teams, electricians, and facility managers, it provides the form, fit, and function needed when replacing an existing breaker in a compatible system.
