BQCH3B070 - 70Amp Circuit Breaker

BQCH3B070 - 70Amp Circuit Breaker

When keeping electrical systems running smoothly, finding the correct replacement breaker is all about matching the original specifications. The BQCH3B070 is a 70 amp, 3-pole bolt-on molded case circuit breaker designed for applications that require a BQCH frame breaker with a 14kA interrupting capacity at 480VAC. Whether you're performing routine maintenance, replacing a failed breaker, or servicing existing distribution equipment, this breaker provides the form, fit, and function needed for compatible installations.

Its bolt-on mounting design creates a secure connection within approved electrical equipment, while the 3-pole configuration makes it well-suited for three-phase power systems commonly found in commercial and industrial environments. The HACR rating also makes it a suitable choice for heating, ventilation, air conditioning, and refrigeration applications where that designation is required. Built to last and engineered for dependable circuit protection, the BQCH3B070 helps protect electrical systems from overloads and short circuits while maintaining compatibility with equipment designed around the BQCH platform.
