• Mounting: Bolt‑on installation for a rigid, high‑load connection
• Part reference: 504C740G19 ensures precise compatibility with Westinghouse panels and systems

Why this matters for your projects

• Efficient replacements: Matching the exact part number guarantees correct trip characteristics and physical fit, reducing downtime during service or upgrades.
• Balanced three‑phase protection: A 3‑pole device safeguards all phases in three‑phase networks, helping prevent unbalanced loads and cascading faults.
• Durable installation in rugged settings: Bolt‑on mounting minimizes loosening from vibration and thermal cycling common in industrial environments.

Ideal use cases

This circuit breaker is a solid choice for maintenance, retrofit, and replacement in facilities with three‑phase power. It’s well suited for manufacturing floors, data centers, and large electrical rooms where exact specifications and secure mounting are essential.

Installation considerations

Before ordering, confirm fit and ratings against your panel documentation. Use the correct mounting torque for the bolts, and verify that your equipment supports a 600 V class circuit breaker. If upgrading from a different ampacity or pole arrangement, plan for any wiring or bus bar adjustments needed for a seamless fit.

What sets it apart

The combination of a bolt‑on mount, 3‑pole configuration, and 100 A rating makes this Westinghouse breaker particularly reliable in secure, high‑demand installations. Rely on the 504C740G19 as your best reference for compatibility to ensure smooth retrofits and maintenance without surprises.
