Square D HDA260502 PowerPact Circuit Breaker – 2 Pole – 50A – 600V – Thermal Magnetic – I-Line Plug-In – 18kA @ 480V

The Square D HDA260502 PowerPact Circuit Breaker is a molded case circuit breaker designed to provide dependable overload and short-circuit protection in commercial and industrial electrical distribution systems. Manufactured by Schneider Electric as part of the PowerPact H-Frame family, this 2-pole breaker combines robust thermal-magnetic protection with the convenience of I-Line style plug-in installation.

Rated at 50A and 600V AC, the HDA260502 utilizes a non-interchangeable thermal-magnetic trip unit with Long-Time and Instantaneous (LI) protection functions. The thermal trip element protects circuits from sustained overload conditions, while the magnetic trip mechanism provides rapid response to short-circuit faults, helping minimize equipment damage and system downtime.

This breaker features an A & C phase connection arrangement and is designed for installation in compatible Square D I-Line panelboards and switchboards using an I-Line bracket mounting system. With a standard interrupting capacity of 18kA at 480V AC and suitability for reverse-fed applications, the HDA260502 delivers reliable circuit protection for a broad range of power distribution applications.

Its compact H-Frame construction, toggle operating handle, and durable molded case design make it an ideal choice for branch circuit protection, feeder circuits, and industrial power distribution systems requiring long-term reliability and performance.
