About SQUARE D POWER PACT HD 150 HDL36150 150A 3 POLE CIRCUIT BREAKER

SQUARE D POWER PACT HD 150 HDL36150 150A 3 POLE CIRCUIT BREAKER

The HDL36150 is a 3-pole PowerPact H-frame unit-mount thermal-magnetic current limiting Circuit Breaker designed to protect electrical systems from damage caused by overloads and short-circuits. This circuit breaker is designed to open and close a circuit by non-automatic means and to open the circuit automatically on a predetermined over-current. The PowerPact H-frame circuit breaker is equipped with dual-break rotating contacts that reduce the amount of peak current during a short-circuit fault. This reduces the let-through currents and enhances equipment protection. The H-frame circuit breaker has an over-center toggle mechanism providing quick-make, quick-break operation. The operating mechanism is also trip-free, which allows tripping even when the circuit breaker handle is held in the ON position. The H-frame circuit breaker has an integral push-to-trip button in the cover to manually trip the circuit breaker. It is suitable for reverse connection.

• 14kA at 600VAC Interrupting rating

• 900A Hold and 1700A trip current

Reliable Circuit Protection for Harsh Environments

PowerPact HD circuit breakers are engineered to withstand rigorous operational demands. Thanks to its -25C to +70C temperature range, high short-circuit ratings, and robust thermal-magnetic protection, the HDL36150 ensures your critical electrical applications remain operational and safe, even in challenging industrial settings. The breaker's front IP40 and terminal IP20 ratings guard against dust and accidental contact, securing personnel and equipment.


Flexible Installation and Superior Performance

The HDL36150's panel mount design and suitability for any mounting orientation provide installation flexibility for modern electrical panels. The standard rotary handle enhances operational convenience and safety, while the mechanical ON/OFF/Trip indicator gives clear status updates. A choice of accessory options, like shunt trip or auxiliary switches, allows seamless integration into distribution networks, facilitating monitoring and control.
