Square D HDA260704 - 70 A, 600 V, 2-Pole Plug-In Circuit Breaker | AmpState

Meet the Square D HDA260704—a 70 A, 600 V, 2-pole plug-in molded case circuit breaker designed to deliver reliable branch circuit protection in panelboards and load centers. Built for quick service and long-term dependability, this breaker combines a fast plug-in connection with a thermal-magnetic trip unit that responds precisely to overcurrent and short-circuit conditions, helping protect wiring, devices, and occupants.

Fast, dependable plug-in installation

The HDA260704 features a streamlined plug-in mounting style that makes installation and replacements faster and simpler than screw-mounted alternatives. This reduces downtime during panel upgrades or circuit maintenance, so electricians can work more efficiently and safely.

Thermal-magnetic protection you can trust

With a thermal-magnetic trip system, this 2-pole breaker provides stable, repeatable protection across a broad range of loads and temperatures. The combination of thermal (long-time) and magnetic (short-circuit) tripping ensures appropriate response, minimizing nuisance trips while safeguarding the circuit and connected equipment.
