Westinghouse | 1313527 | Circuit Breaker | 150A | 3-Pole | 600V | Bolt-On

Westinghouse 1313527 Circuit Breaker is a robust 150A, 3-Pole, 600V bolt-on protection device designed for demanding electrical environments. Built for maintenance, retrofit, and replacement projects where exact specifications matter, this breaker delivers dependable performance in industrial and commercial panels that require solid protection and reliable operation.

• Amperage: 150A
• Poles: 3-Pole (three-phase protection)
• Voltage Rating: 600V
• Mounting Type: Bolt-On for secure, field-friendly installation

Key advantages and use cases

The bolt-on design provides a sturdy mechanical connection to the panel, helping to ensure stable operation in environments with vibration or heavy electrical loads. This makes the 1313527 an ideal choice for:

• Replacing worn or failed main breakers in 3-phase panels
• Retrofits where a 150A, 3-pole, 600V protection device is required
• New installations or panel upgrades that call for a bolt-on, high-current breaker

Why this Westinghouse breaker stands apart

What sets the 1313527 apart is its exact alignment with Westinghouse panel families that use bolt-on, 3-pole configurations at 600V. It’s designed to maintain consistent trip performance and reliable disengagement under fault conditions, helping you meet safety and code requirements without compromise. Its 150A rating makes it suitable for main protection in many commercial and light-industrial applications, where clean, predictable shutoffs minimize downtime.

Compatibility and installation notes

For the best results, confirm fit and ratings before ordering. The part number 1313527 is your strongest reference for compatibility, so cross-check it against your panel’s labeling and manufacturer instructions. When installing, follow the panel manufacturer’s torque specs for bolt-on breakers and ensure the bus connections are clean and free of corrosion before securing the unit.

Practical tips for optimal performance

• Inspect the panel seating area and bus bars for any signs of wear before replacement.
• Use the exact part number during order to avoid mismatches in mounting footprint and trip characteristics.
• Store spare breakers in a clean, dry environment to preserve terminal integrity and spring tension.
