Breaker (RSX) 3/4 HP | 110100.0012

Is your Overhead Door RSX commercial operator dead, or does it keep cutting out mid-cycle? The operator's circuit breaker protects the motor circuit from overloads. When a breaker wears out or keeps tripping under a normal load, the operator stops running and the door won't move under power. This is the genuine Overhead Door replacement breaker for 3/4 HP, single-phase RSX operators.

Does this fit my operator?

• Overhead Door RSX commercial operators with a 3/4 HP, 1-phase motor
• Listed in Overhead Door's RSX parts diagrams for the hoist, release, drawbar, and side mount configurations
• How to confirm: check the operator's nameplate for model (RSX), horsepower (3/4 HP), and phase (1 phase). For a 1 HP, 1-phase RSX, you need breaker 110100.0015 instead

Installation Notes

This is an electrical repair on a commercial operator. It should be done by a qualified technician.

Disconnect power at the source and follow lockout/tagout procedures (OSHA 1910.147) before opening the electrical box. Note or photograph the wiring on the old breaker, then remove it and install the new breaker with the wires in the same positions. Close the electrical box, restore power, and run the door through a full open and close cycle to confirm the operator runs normally without tripping. If the new breaker trips right away, check for a mechanical bind in the door or a motor problem before resetting it again.
