• Poles: 3-Pole
• Voltage rating: 600 V
• Part number: LEP36100LSG

Why this breaker matters in practical applications

This LEP-series Siemens (Square D) device is purpose-built for environments where exact spec matching matters—industrial control panels, service entrances, and distribution panels that demand reliable 3-phase protection at 600 V. The 3-pole configuration provides coordinated protection across all three phases, helping prevent arc faults and equipment damage in demanding electrical installations.

Ideal use cases

• Retrofits in legacy 600 V, 3-phase panels where a 100 A protection point is required.
• Maintenance replacements to maintain original protection schemes without introducing mismatched ratings.
• Panel upgrades or rebuilds where preserving the LEP-series footprint ensures a seamless fit with existing bus and mounting arrangements.

Compatibility and ordering guidance

Important: Confirm fit and ratings against your panel labeling before ordering. The LEP36100LSG part number is the best reference for ensuring compatibility with your electrical system. If your panel instructions specify a 3-pole, 100 A, 600 V breaker in the LEP family, this unit is designed to align with those requirements and mounting dimensions.

Installation and practical considerations

• Ensure the power is isolated and follow proper lockout/tagout procedures before installation.
• Inspect mounting hardware and verify that terminal connections are secure to maintain reliable fault clearance.
• Use only in panels designed to accept LEP-series breakers to preserve safety standards and coordination.

What you gain with the LEP36100LSG

Choosing this Square D breaker means you’re selecting a component aligned with standard 600 V three-phase systems, designed for dependable protection with straightforward replacement in compatible panels. It supports your uptime goals by delivering predictable performance, simplifying maintenance cycles, and ensuring that your electrical protection remains consistent with the rest of your Square D infrastructure.
