Westinghouse | LC3100 | Circuit Breaker | 100A | 3-Pole | 600V

Meet the Westinghouse LC3100 Circuit Breaker — a dependable 100A, 3-Pole protection device designed for 3-phase systems up to 600V. Built for maintenance, retrofit, and replacement projects where exact specifications matter, this unit slides into compatible LC-series panels with minimal downtime and preserves the integrity of your electrical distribution.

• Amperage: 100 A
• Poles: 3-Pole for comprehensive 3-phase protection
• Voltage rating: 600 V (AC)
• Application: ideal for maintenance, retrofit, and replacement when LC3100 compatibility is required
• Compatibility reference: LC3100 is the best part number to verify fit

The LC3100 from Westinghouse is crafted to maintain reliable shutdown performance across all three phases, helping prevent overloads and short-circuit faults from propagating through sensitive equipment. Because it matches the LC-series form factor, you can count on a straightforward swap that preserves existing wiring configurations and panel layout—reducing installation time and downtime.

Ideal use cases

Perfect for commercial and industrial environments that rely on stable 3-phase distribution at up to 600V. Use it during panel upgrades or replacements, when stocking spare parts for maintenance teams, or in retrofit projects where keeping the original part number is critical for safety and warranty compliance.

• Manufacturing facilities with 3-phase motors and conveyors
• Commercial buildings with centralized power distribution
• Data centers or technical rooms requiring balanced, three-phase protection

Practical tips for ensuring the right fit

Before ordering, cross-check the panel’s original specifications and confirm LC-series compatibility. The 3-Pole, 100A, 600V rating should align with your system’s three-phase configuration and voltage. Keeping a spare LC3100 on hand can streamline maintenance workflows and minimize disruption during replacements. Remember: the LC3100 part number is your most reliable reference for compatibility with your panel or main distribution board.
