VacuMaid 16 Amp Mechanical Circuit Breaker for Central Vacuums

When a central vacuum motor pulls more current than its wiring is rated for, a stuck impeller, a fully clogged filter, or a jammed hose are the usual causes, and the circuit breaker is what stops that overload from cooking the motor windings. This one is rated 16 amps, built for VacuMaid power units on that circuit rating.

It resets with a button rather than needing replacement after every trip, so once the jam or blockage causing the overload is cleared, pressing the breaker back in restores the unit without opening the canister or ordering a part. Repeated tripping under otherwise normal use, or a unit that refuses to power on at all, points to a worn or failed breaker well before it points to the motor, especially once the filter has been checked and cleaned and the hose run through for obstructions with no change in behavior.

The rating matters more than the model of power unit it came out of. Check the amperage printed on the breaker being replaced rather than assuming from the power unit's model name, since two units in the same product family can ship with different breaker ratings depending on motor size, and a sticker or stamped number on the breaker body is the reliable source, not memory or a parts list from a different unit.

A mismatched amperage either trips too soon under normal load or leaves the motor under-protected, so confirm the number on the old breaker before ordering rather than assuming it matches a sibling unit in the same product line. Dealer fitment charts pair the 16 amp rating with later-production SR52 and SR52H units among others, and the date qualifiers on those listings are exactly why the stamped number settles it.
