Meet the Westinghouse RJ3125 Circuit Breaker — a bolt-on, 3-pole protective device engineered for reliable overcurrent protection in demanding electrical environments. With a 125A rating and 600V capability, this breaker is designed for maintenance, retrofit, and replacement projects where exact specifications matter and compatibility is non-negotiable.
This breaker excels in protecting and isolating large 3‑phase circuits in commercial and light industrial settings. Its bolt-on form factor provides a secure, solid connection to compatible panels, making installation straightforward for service technicians performing maintenance, retrofits, or replacements where the RJ3125 spec is required.
Ideal use scenarios include panel upgrades, feeder protection, and retrofit projects where 3‑phase reliability at 600V is essential. The RJ3125 helps minimize downtime by delivering dependable interruption performance exactly where you need it, keeping critical equipment safeguarded against electrical faults.
Important notes to ensure a perfect fit: confirm the breaker’s fit and ratings before ordering. The part number RJ3125 is the most reliable reference for compatibility, so use it to verify against your panel’s catalog or service documentation before you purchase.
