Why this 633115 stands out for industrial protection

In three-phase installations, a 3-pole breaker provides coordinated protection across all phases, ensuring a safe shutdown if overloads or faults occur. The 480V rating makes this unit suitable for common industrial power systems, from manufacturing lines to large drives and motor control centers. With the 633115, you’re relying on a trusted Cutler-Hammer design that emphasizes reliability and compatibility with Eaton's industrial breakers ecosystem.

Ideal use cases

• Motor control centers and machine panels in manufacturing facilities
• Service and replacement parts for aging 480V electrical systems
• Distribution panels requiring quick, reliable three-phase protection

Compatibility and fit

Notes: Verify fit by part number and application requirements. The part number is 633115, which you can use to confirm compatibility with your existing panel, MCC, or distribution board. If you need help matching a part number or confirming compatibility, message us and we'll help.

How this compares to other configurations

For three-phase 480V systems, a 3-pole solution like this keeps all three phases in sync, reducing the risk of phase imbalance and equipment damage compared to single- or two-pole configurations in similar loads. Always match the breaker to your panel's rated voltage, number of poles, and the load profile.

Practical tips & installation notes

• Confirm the breaker is the correct Eaton/Cutler-Hammer style for your panel by checking the part number (633115) and your panel’s data plate.
• Before installation, ensure the circuit is de-energized and the device is rated for 480V systems.
• Follow manufacturer torque specs for termination and use appropriate safety procedures during replacement.
• Keep spare parts organized and label replacements by part number for future maintenance.
