Square D HJL36050M72 Circuit Breaker 50A 600V 3 Pole

Product Description

The SQUARE D HJL36050M72 is a 3-pole, panel mount circuit breaker rated at 50 amps and 600 volts, featuring an electronic trip mechanism. It is designed for overcurrent protection in commercial and industrial power distribution panels. The electronic trip unit delivers precise fault detection compared to thermal-magnetic designs, making it suited for applications where accurate trip thresholds are required. Licensed electricians install this breaker as part of branch circuit or feeder circuit protection in switchboards, panelboards, and load centers operating at up to 600 volts AC.

This breaker is appropriate for use in commercial and industrial electrical distribution systems where 3-pole, 600-volt protection is required. Typical installations include motor branch circuits, feeder protection, and multi-phase load circuits in facilities requiring reliable overcurrent interruption. The electronic trip mechanism supports multiple breaking capacity ratings, providing flexibility across varying fault current environments. It is a panel mount configuration, intended for fixed installation within a compatible enclosure or distribution board.

Key Features

• Electronic trip mechanism for precise overcurrent and fault detection

• Rated 50 amps continuous current at 600 volts
• Multiple breaking capacity ratings for versatile fault current applications
• Lug terminal connection type for direct conductor termination
• Panel mount configuration for fixed installation in distribution equipment

Compatibility

Designed as an OEM-style replacement and panel mount circuit breaker for commercial and industrial 3-pole, 600-volt distribution panels and switchboards requiring electronic trip overcurrent protection.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panel before installing or removing the breaker. Verify lug terminal torque requirements and conductor sizing according to the equipment labeling and NEC Table specifications. Do not exceed the breaker rated voltage or ampacity for the intended circuit.
