Square D HDA260501 PowerPact Circuit Breaker – 2 Pole – 50A – 600V – Thermal Magnetic – I-Line Plug-In – 18kA @ 480V

The Square D HDA260501 PowerPact Circuit Breaker is a high-performance molded case circuit breaker designed for dependable protection of electrical distribution systems in commercial and industrial environments. Manufactured by Schneider Electric and part of the PowerPact H-Frame family, this 2-pole breaker provides reliable thermal-magnetic protection against overloads and short-circuit faults.

Rated at 50A and 600V AC, the HDA260501 incorporates a non-interchangeable thermal-magnetic trip unit with Long-Time and Instantaneous (LI) protection functions. The thermal element responds to prolonged overload conditions, while the magnetic trip mechanism delivers rapid interruption of high fault currents to help protect conductors, equipment, and connected loads.

The breaker features an I-Line style plug-in connection and mounting bracket design for quick installation into compatible Square D I-Line panelboards and switchboards. Configured with an A & B phase connection arrangement, the HDA260501 offers a standard interrupting capacity of 18kA at 480V AC and includes load-side lug terminals for secure field wiring.

Its compact H-Frame design, toggle operating handle, and rugged molded case construction make the HDA260501 an excellent solution for branch circuit protection, feeder applications, and industrial power distribution systems requiring reliable and long-lasting circuit protection.
