Westinghouse | RLM3150 | Circuit Breaker | 150A | 3-Pole | 600V

Westinghouse RLM3150 is a robust, high-capacity circuit breaker designed to protect large three‑phase electrical systems. With a rating of 150A and three poles, this unit is built to reliably interrupt fault current in demanding 600V applications, making it a trusted choice for both maintenance projects and full-scale retrofits.

• Amperage: 150A
• Poles: 3‑Pole
• Voltage: 600V
• Reference: Part number RLM3150 serves as the primary compatibility guide

Designed for maintenance, retrofit, and replacement scenarios, the Westinghouse RLM3150 delivers reliable protection for three‑phase loads while enabling smooth, field-ready swaps in compatible panels. It’s especially well-suited for industrial equipment, commercial electrical rooms, and other environments where consistent, high‑volume current control is essential.

Key benefits that matter in the real world

• Precise compatibility: Use the RLM3150 part number as the best reference to ensure a correct fit in Westinghouse‑compatible panels and replacement projects.
• Three‑phase protection: Safeguards large motors, compressors, and other 3‑phase equipment from overload and short-circuit events, helping reduce downtime and equipment damage.
• Streamlined maintenance and upgrades: A direct swap in your existing panel minimizes service time and disruption during upgrades or routine servicing.
• Future‑proofing for 600V systems: Designed to operate within common 600V distribution schemes, aligning with many commercial and industrial electrical architectures.

Practical use cases: upgrading a data center feeder, replacing a failed 3‑pole breaker in a commercial service panel, or retrofitting an industrial control cabinet that runs heavy three‑phase loads. This breaker is a practical choice wherever you need dependable 150A protection without compromising on panel compatibility.

Before you order, verify the fit and ratings for your specific installation. The RLM3150 is the go‑to reference when matching Westinghouse breakers to existing gear, ensuring you maintain protection standards and electrical code compliance across your system.
