Westinghouse | J3175 | Circuit Breaker | 175A | 3-Pole | 600V | 22kA | Bolt-On

The Westinghouse J3175 circuit breaker delivers reliable, three‑phase protection for demanding electrical systems. Designed for installations up to 600V, this 175A, 3‑pole unit combines solid fault protection with a bolt‑on mounting style for secure, easy service in industrial and commercial panels.

Key to its value is the 22kA interrupting capacity, which helps minimize downtime during fault events and protects downstream equipment in high‑energy environments. With the J3175 part number as your compatibility anchor, you’ll have a precise match for Westinghouse panels and replacement projects that require exact specs.

Key specifications

• Amperage: 175A
• Poles: 3‑Pole
• Voltage: 600V
• Interrupting capacity: 22kA
• Mounting: Bolt‑On
• Reference: Part number J3175 for compatibility

Why it matters for your system

In real-world installations, the combination of a 3‑pole configuration and a 600V rating supports stable protection across three‑phase distribution. The bolt‑on design enhances mechanical stability and simplifies replacement in panels that require a secure, maintenance‑friendly mounting method. The 22kA interrupting rating provides a robust safety margin for fault currents typical in commercial and light industrial environments.

Ideal use cases

• Maintenance or retrofit projects in Westinghouse‑compatible electrical panels
• Replacement for aging circuit breakers where exact J3175 specifications are needed
• New installations in commercial or light industrial systems that operate at up to 600V

Installation and compatibility tips

To ensure a proper fit and reliable performance, verify the panel model and the bus design before ordering. Use the J3175 part number as the primary reference to confirm compatibility with your equipment. When installing, follow standard safety procedures: de‑energize the system, secure the bolt‑on mounting, and test the circuit protection function after installation to confirm proper operation.
