90-80122 Combination Reversing Starter Modification, Size 0, 250VAC, Nema 12 Enclosure (M145 Mod)

The Combination Reversing Starter with Circuit Breaker (CB) modification provides all control equipment that is not mechanically connected to the door operator powerhead in a separate Wall Mount NEMA 12 rated enclosure. The limit switches and brake solenoid (when supplied) remain on the door operator In addition to the normal control equipment (starter, control transformer, control relays), a Circuit Breaker with external handle is supplied, which shuts off the main power to the unit (and door operator also) when the cover is opened. The circuit breaker is rated for up to 250VAC incoming power; therefore, this version of the modification may be used only with door operators where the incoming power is 250VAC or less. The starter itself is an industrial size 0 but may be upgraded to size 1 see (M153) and the control transformer is rated 50VA but may be upgraded to 100VA see (M155). Terminal points are provided both for the inter-wiring between operator/starter and for the connection of control stations and safety equipment. Price includes an automatically resettable overload relay which may be converted to manual reset, but cover of starter must be opened to reset. For external manually resettable overload see (M152). This modification must be factory supplied.
