Key specifications

• Part Number: LE36150LSG
• Current rating: 150 A
• Pole configuration: 3-pole
• Voltage rating: 600 V

Why this 3-pole, 150A, 600V breaker stands out

The LE36150LSG is purpose-built for three-phase circuits up to 150 amps, making it an ideal choice for protecting motor drives, conveyors, pumps, and other heavy-load equipment in industrial facilities. With a 600 V rating, it’s suited for higher-voltage distribution in commercial settings and certain industrial environments, helping to prevent damage from overloads or short circuits while enabling safe, predictable shutdowns when faults occur.

Concrete value you can rely on

• Reduces the risk of equipment damage by interrupting excessive current before it travels through motors and wiring.
• Durable, mission-critical design: Built to endure demanding operating conditions, contributing to longer service life and lower maintenance needs in active power-distribution panels.
• Clear compatibility within Square D ecosystems: Seamless integration with Square D panels and legacy LE-series installations, helping you maintain a cohesive protection strategy across your facility.

Ideal applications

• Three-phase motor circuits in manufacturing floors, processing lines, and material handling
• Industrial feeders supplying pumps, fans, and compressors in HVAC and processing environments
• Commercial and light-industrial power distribution where 600 V systems are in use

How it benefits your operation

By providing dependable overcurrent protection, the LE36150LSG helps minimize unexpected equipment failures, protects wiring insulation from thermal damage, and supports safer maintenance procedures. The result is less unplanned downtime, longer equipment life, and a more predictable power distribution strategy for facilities that rely on steady three-phase performance.

Practical installation and maintenance tips

• Verify that your panel or enclosure is designed to accept LE-series, three-pole devices and that the mounting and electrical connections align with your system.
• Plan for appropriate wiring size and conductors capable of safely carrying up to 150 A and withstanding the voltage rating of 600 V.
• Follow standard electrical safety practices and the manufacturer’s installation guidelines when replacing or upgrading breakers in active systems.
• Schedule periodic inspections to confirm the breaker shows no signs of wear, overheating, or corrosion, and test the protective function according to maintenance protocols.

For installations requiring solid, dependable three-phase protection at 150 amps and up to 600 volts, the Square D LE36150LSG 150A 3-Pole 600 V Circuit Breaker delivers clear, concrete value—enabling safer operation, smoother maintenance, and resilient power distribution across demanding environments.
