Westinghouse | RJ3175L | Circuit Breaker | 175A | 3-Pole | 600V | Bolt-On

Meet the Westinghouse RJ3175L circuit breaker—a trusted bolt-on solution engineered for robust 3-phase protection in demanding electrical systems. With a 175A rating and a 600V maximum, this device is designed for reliable performance in retrofit, maintenance, and replacement projects where exact specs matter.

Key specifications at a glance

• Amperage: 175A
• Poles: 3-Pole
• Voltage: 600V
• Mounting: Bolt-On
• Part reference: RJ3175L

Why choose the RJ3175L for your panel

• Precise compatibility for retrofits and replacements. The RJ3175L is specifically referenced by part number, making it the clear choice when matching existing panel layouts and electrical ratings.
• Secure bolt-on installation. Designed for panels that require a sturdier mounting method, this bolt-on configuration reduces vibration and maintains consistent contact under load.
• Three-phase protection. The 3-Pole design provides balanced interruption across all conductors in a 3-phase system, helping prevent uneven loading and protecting equipment from phase faults.
• High-current capacity with sensible limits. The 175A rating supports substantial branch circuits while preserving short-circuit protection for connected equipment up to 600V.

Ideal use cases

• Retrofit projects in commercial or light industrial panels that require a bolt-on, 3-pole breaker with a 175A rating.
• Replacement of damaged or worn breakers in systems designed for 600V operation, ensuring continuity of protection and compliance with existing specifications.
• Maintenance tasks where you need exact part-number alignment (RJ3175L) to guarantee compatibility with current panel catalogs and service manuals.

How to verify compatibility and install

Before ordering, double-check that your panel’s design supports a bolt-on, 3-pole breaker with a 600V rating and a 175A continuous current capacity. Use RJ3175L as the primary reference for compatibility to align with the panel’s electrical catalog. When installing, follow standard safety protocols for shutting off power, establishing proper grounding, and securing the breaker firmly to the bus bar and mounting studs.

Practical considerations for best results

• Keep a spare RJ3175L on hand for planned maintenance or future upgrades to minimize panel downtime.
• Document the part number in your maintenance logs to streamline future replacements and audits.
• Coordinate with your panel’s documentation to ensure the bolt-on mounting scheme is supported and that the surrounding circuit capacity aligns with a 175A, 3-Pole, 600V device.

With the Westinghouse RJ3175L, you’re selecting a dependable, specification-driven circuit breaker tailored for precise retrofits, reliable replacements, and long-term protection in 3-phase, 600V systems.
