Square D HDA260404 PowerPact Circuit Breaker – 2 Pole – 40A – 600V – Thermal Magnetic – I-Line Plug-In – 18kA @ 480V

The Square D HDA260404 PowerPact Circuit Breaker is a compact molded case circuit breaker designed to provide dependable overload and short-circuit protection in commercial and industrial power distribution systems. Manufactured by Schneider Electric as part of the PowerPact H-Frame product family, this 2-pole breaker combines reliable thermal-magnetic protection with convenient I-Line plug-in installation for use in compatible Square D distribution equipment.

Rated at 40A and 600V AC, the HDA260404 utilizes a non-interchangeable thermal-magnetic trip unit with Long-Time and Instantaneous (LI) protection functions. The thermal element protects conductors and equipment from sustained overload conditions, while the instantaneous magnetic trip mechanism responds rapidly to short-circuit faults, minimizing damage and improving system safety.

Built on the PowerPact H-Frame platform, this breaker features a B & C phase connection arrangement and an I-Line style plug-in design that simplifies installation and replacement in Square D I-Line panelboards and switchboards. With a standard interrupting capacity of 18kA at 480V AC and reverse-feed suitability, the breaker provides reliable protection for a wide range of electrical distribution applications.

Its rugged molded case construction, toggle operating handle, and compact footprint make the HDA260404 an excellent solution for branch circuit, feeder, and equipment protection requirements.
