Square D GJL36075M06 - 75A, 3-Pole, Circuit Breaker

Introducing the Square D GJL36075M06 — a 75A, 3-Pole circuit breaker designed for dependable overcurrent protection in demanding electrical environments. This 3-Pole configuration is ideal for three-phase systems, delivering reliable disconnection across all phases to safeguard equipment, wiring, and personnel in real-world panel assemblies.

Key specifications

• Current rating: 75A
• Poles: 3-Pole
• Breaker type: Circuit Breaker

Why this 3-Pole breaker matters

In distribution panels, switchboards, and control panels, a 3-Pole breaker like the GJL36075M06 ensures simultaneous trip across all three phases. This coordinated protection reduces the risk of unbalanced loads and protects three-phase motors, drives, and feeders from phase-to-phase faults. For industrial and commercial applications, that translates to safer operation, reduced downtime, and clearer fault isolation during maintenance or emergencies.

Ideal use scenarios

• Panelboards and switchboards feeding three-phase equipment
• Motor control centers (MCCs) and motor drives requiring consistent phase protection
• Industrial OEM assemblies where standardized, reliable overcurrent protection is needed
• Commercial electrical gear that relies on three-phase distribution with durable, easy-to-replace protection

Unique value and practical benefits

• Brand reliability: Square D has a long-standing reputation for rugged, dependable protection in demanding environments.
• Configurable three-phase safety: The 3-Pole design ensures all phases are protected and can trip together, preventing partial faults from compromising the system.
• Versatile integration: Sized for use in common distribution panels, switchboards, and control panels where three-phase protection is required.
• Clear maintenance path: Designed for straightforward replacement and compatibility with existing Square D installations, reducing downtime during maintenance or upgrades.

Installation and operational guidance

To maximize protection and ensure compatibility, verify that your system is three-phase and that the load current aligns with the 75A rating. When replacing an existing device, confirm the 3-Pole configuration matches your panelboard or MCC requirements and follow standard safety procedures for disconnecting power before service. This breaker is built to perform reliably in distribution and motor-control contexts where steady, predictable protection is essential.

Who benefits most

Industrial facilities, commercial electrical rooms, and OEM manufacturers seeking a robust, three-phase overcurrent protection solution that integrates smoothly with Square D panel systems and MCCs will find the GJL36075M06 to be a precise fit for dependable circuit protection and easy maintenance.
