Product details
Part R8452B is the 2.5 amp resettable circuit breaker used in Rexair Rainbow power nozzles, and it replaces the breaker on the Rainbow D4-SE and on the PN-2E, PN-3 and PN-3A power nozzles.
The breaker trips when the brush roll binds up on debris such as a sock, a stray thread of carpet fringe, or hair wound tight around the shaft, and the motor starts pulling more current than it should. Clearing the obstruction and letting the nozzle cool usually lets the breaker reset and hold. A reset that will not hold once the obstruction is cleared, or one that trips again within a few seconds every time, means the breaker itself has worn out and needs swapping rather than resetting.
- Part: R8452B, 2.5 amp
- Fits: Rainbow D4-SE, PN-2E, PN-3, PN-3A power nozzles
- Function: resettable overcurrent protection for the nozzle motor
Confirm your power nozzle model before ordering to make sure this breaker matches your nozzle.
A nozzle that trips its breaker occasionally under a heavy load, such as a thick rug fringe, is behaving normally. One that trips every time the roller spins freely, or trips again within minutes of every reset, has a breaker that can no longer hold its rated load and should be replaced rather than reset repeatedly.
