Square D HJA36060 - 60 A, 600 V, 3-Pole Plug-In Circuit Breaker | AmpState

Square D HJA36060 is a 60A, 600V, 3-pole plug-in molded case circuit breaker designed to shield your electrical system from overloads and short circuits. This device slots into compatible OEM panelboards and load centers with a plug-in connection, enabling fast, tool-free installation and simple field replacement when service needs arise.

• Fast plug-in connection for quick installation and replacement — minimize downtime during panel maintenance or upgrades.
• Thermal-magnetic trip unit delivers stable, repeatable protection by responding to both overload (thermal) and short-circuit (magnetic) events, helping protect wiring and downstream devices.
• 3-pole configuration provides coordinated disconnection for 3-phase systems, improving safety and trip performance in commercial and light-industrial panels.
• OEM compatibility is designed to work with matching Square D panels and other OEM load centers that accept plug-in molded case breakers.
• Versatile applications suitable for residential, commercial, and light industrial environments where branch-circuit overcurrent and short-circuit protection is essential.
