Westinghouse | 504C743G02 | Circuit Breaker | 70A | 2-Pole | 600V | Bolt-On

Westinghouse 504C743G02 Circuit Breaker is a purpose-built solution for reliable protection in high-demand electrical systems. This 70A, 2-pole, 600V bolt-on breaker is designed for installations that require a secure, bolted connection and robust overcurrent protection.

Ideal for maintenance, retrofit, and replacement projects, this unit helps you preserve system safety and performance when upgrading panels or circuits that demand the exact specifications of a bolt-on, 2-pole design.

• Amperage: 70A
• Poles: 2-Pole
• Voltage rating: 600V
• Mounting type: Bolt-On
• Part number: 504C743G02 (best reference for compatibility)

Who should consider this breaker? Electricians and maintenance teams working on industrial or commercial panels that require a bolt-on, high-current protection device. It’s especially suitable for replacing failed breakers in systems where a 2-pole configuration and 600V rating are essential, or when upgrading older equipment to meet current electrical codes and load requirements.

Why this matters: A bolt-on design offers a solid, soldered-like connection that remains secure under vibration and load fluctuations, reducing the risk of loose connections and nuisance trips. The 70A rating protects heavy-load circuits—such as motor circuits, HVAC equipment, and other high-demand branch circuits—without compromising safety or performance.

Practical usage tips:

• Before ordering, confirm fit and ratings against your panel’s documentation. The 504C743G02 part number is the most reliable reference for compatibility.
• Use only in panels designed for bolt-on breakers of this specification to ensure proper engagement and trip performance.
• Ensure the surrounding panel portion and bus connections are clean and free of corrosion to maintain a solid electrical connection.
• Follow your panel manufacturer’s torque and installation guidelines during mounting to avoid over-tightening or under-tightening.

This Westinghouse breaker stands out by pairing a clear, exact specification with the security of bolt-on mounting, delivering dependable protection for critical circuits while simplifying future maintenance and replacements. If you’re upgrading or restoring a panel that requires a 70A, 2-pole, 600V bolt-on solution, the 504C743G02 is a precise match that keeps your electrical system aligned with safety and performance expectations.
