Square D HDA260702 PowerPact Circuit Breaker – 2 Pole – 70A – 600V – Thermal Magnetic – I-Line Plug-In – 18kA @ 480V

The Square D HDA260702 PowerPact Circuit Breaker is a molded case circuit breaker designed for reliable overload and short-circuit protection in commercial and industrial electrical distribution systems. Manufactured by Schneider Electric as part of the PowerPact H-Frame series, this 2-pole breaker combines proven thermal-magnetic trip technology with a convenient I-Line plug-in mounting system for fast installation and dependable performance.

Rated at 70A and 600V AC, the HDA260702 features a non-interchangeable thermal-magnetic trip unit with Long-Time and Instantaneous (LI) protection functions. The thermal element protects against sustained overload conditions, while the instantaneous magnetic element responds quickly to short-circuit faults, helping protect downstream equipment and electrical infrastructure.

Designed for Square D I-Line panelboards and switchboards, the breaker uses an I-Line plug-in connection system for secure mounting and simplified installation or replacement. Its A & C phase connection configuration and rugged H-Frame construction make it suitable for a wide range of power distribution applications.

With a standard interrupting capacity of 18kA at 480V AC and reverse-feed capability, the HDA260702 is well-suited for branch circuit and feeder protection in demanding electrical environments.
