Westinghouse | LA3600WK | Circuit Breaker | 600A | 3-Pole | 600V | Bolt-On

The Westinghouse LA3600WK circuit breaker is built for demanding, high-load environments where dependable three‑phase protection matters. This bolt-on, 3‑pole unit handles up to 600A at voltages up to 600V, making it a robust choice for maintenance, retrofit, and replacement projects in industrial and commercial panels.

• Amperage: 600A
• Poles: 3‑Pole
• Voltage: 600V
• Mounting: Bolt-On

What sets the LA3600WK apart is its bolt-on design, which delivers a secure, vibration‑resistant connection ideal for higher‑demand applications. The three‑pole configuration provides true three‑phase protection, helping to evenly interrupt faults across all phases and protect both equipment and personnel in power distribution systems.

Key use cases include:

• Routine maintenance and part replacement in legacy Westinghouse installations or compatible panels
• Retrofit projects where upgrading to a 600A, 3‑pole, 600V protection device is required
• Replacement for aging or failed breakers in industrial or commercial electrical circuits
• Protection for large motors, HVAC systems, and other high‑current loads on 3‑phase networks

Why choose this specific model? The LA3600WK is designed to align with exact compatibility references, with the part number serving as your best reliability checkpoint. Before ordering, confirm that your panel or enclosure supports a 600A, 3‑pole, 600V bolt‑on breaker of this style to ensure a seamless fit.

Installation and safety tip: Always power down the system and follow lockout/tagout procedures. Use the correct mounting hardware and refer to your panel’s manufacturer guidelines and local electrical codes. For best results, have a licensed electrician verify fit, ratings, and torque requirements before energizing the circuit.

With Westinghouse reliability and a design focused on secure mounting and solid trip performance, the LA3600WK delivers peace of mind for critical power protection in demanding environments.
