Square D HDL36060 - 60 A, 600 V, 3-Pole Circuit Breaker | AmpState

Square D HDL36060 — a 60A, 600V, 3-Pole molded case circuit breaker designed for dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Built to fit seamlessly into existing Square D installations, it delivers durable performance where reliability matters most.

The design emphasizes efficiency and reliability. Its compact molded-case form factor frees up valuable panel space, making it ideal for crowded electrical enclosures or retrofit projects where every inch counts. The thermal-magnetic trip unit provides stable, repeatable protection: the thermal element handles sustained overloads with predictable timing, while the magnetic element responds instantly to severe short circuits, helping to minimize damage and downtime.

Compatibility is a core strength. This 3-Pole breaker is compatible with matching OEM load centers and panelboards, ensuring consistent trip characteristics and straightforward replacement in existing systems. With its 60A rating and 600V capability, it is suited for residential, commercial, and light industrial electrical setups that demand reliable protection across three-phase configurations.
