Square D HDA36050AABCSD 36050A 3-Pole 600 V Circuit Breaker

The Square D HDA36050AABCSD 36050A 3-Pole 600 V Circuit Breaker is engineered to shield three-phase electrical systems from overcurrent events. With a 3-pole configuration and a 600 V rating, it provides synchronized interruption across all phases, helping protect motors, feeders, and panelboards from damaging faults.

Core specifications

• Part Number: HDA36050AABCSD
• Current rating: 36050 A
• Poles: 3
• Voltage rating: 600 V

Why this 3-pole design matters

Three-pole breakers trip all circuit conductors together, eliminating the risk of a partially energized motor or equipment. This common-trip approach simplifies wiring and enhances safety in any 3-phase distribution panel.

Ideal use cases

• Industrial equipment and motor feeders in manufacturing facilities
• Commercial buildings with three-phase power distribution
• Data centers and other critical systems requiring reliable fault protection

Practical considerations

To get the most from the HDA36050AABCSD, pair it with a panelboard or switchgear designed for Square D 3-pole devices and ensure the circuit’s running load aligns with the 36050 A rating. Proper installation and periodic inspection of connections, seating, and bus compatibility help maintain consistent performance over time.
