MQJ3200KL | Circuit Breaker | 200A | 3-Pole | 240V

MQJ3200KL is an industrial circuit breaker engineered for reliable protection in high-demand electrical systems. With a 200A rating, three poles, and a 240V operating window, this unit is designed for maintenance, retrofit, and replacement projects where exact spec matching matters.

• Amperage: 200A
• Configuration: 3-Pole (three-phase protection)
• Voltage rating: 240V
• Reference for compatibility: Part number MQJ3200KL is the best reference to ensure a proper fit

Why this matters

The MQJ3200KL provides synchronized overcurrent protection across all three conductors in a 240V system, helping prevent damage to motors, drives, and other industrial equipment. Its 200A rating makes it suitable for mid-size feeders and main distribution paths where robust protection is essential.

Ideal use cases

• Maintenance and retrofit projects where you need to replace worn breakers with an exact 200A, 3-pole, 240V unit.
• Replacement in panels that require the MQJ3200KL specification to maintain trip characteristics and mounting compatibility.
• Upgrading protection for three-phase loads in manufacturing, processing lines, or large HVAC or pumping systems.

What makes it stand out

Unlike generic substitutes, the MQJ3200KL is purpose-built to match the exact electrical and mechanical footprint of systems designed for a 200A, 3-pole, 240V circuit. This reduces installation guesswork, minimizes downtime, and ensures consistent trip behavior across your protected circuit.

Practical tips for ordering and installation

• Before ordering, verify fit and ratings against your panel's label. The MQJ3200KL part number is the best reference for compatibility.
• When installing, ensure proper torque on terminations to accommodate 200A conductors and maintain reliable connections.
• Keep a spare MQJ3200KL on hand for planned maintenance or unexpected outages to minimize downtime.
