The MMTC PBS-3FRS is a NEMA 1 interior three-button surface-mount control station labeled for FORWARD, REVERSE, and STOP. It is used where the operator or equipment movement is better described by directional motor commands instead of OPEN-CLOSE or UP-DOWN labels. Typical applications can include compatible industrial equipment, specialty door controls, conveyor-type equipment, or operator circuits designed for forward and reverse commands.
This station is a command device, not a motor controller by itself. It must be connected to a compatible control circuit that is designed to accept these momentary push-button inputs. The STOP circuit should be checked against the wiring diagram because stop functions are often wired differently than the movement commands.
PBS-3FRS should not be selected just because it has three buttons. It belongs to the PBS interior surface-mount family, but the legends and intended use are different from PBS-3, PBS-3UDS, and foreign-language PBS-3S versions. Match the part number, labeling, contact logic, and enclosure before replacing an existing station.
This product is commonly used with the following applications when the operator control circuit, wiring terminals, enclosure needs, and site layout match the part being replaced or added:
Because control stations and accessory devices are wired into the operator control circuit, verify the terminal labels, contact type, voltage rating, enclosure rating, and required command functions before ordering.

PBS-3FRS is intended for forward/reverse labeled circuits. If the equipment is a door or gate using OPEN-CLOSE-STOP terminology, verify that this label set is acceptable before ordering.
Installation should follow the operator manufacturer's wiring diagram and all applicable safety requirements. Do not bypass stop circuits, monitored safety devices, entrapment protection, or required warning devices. If the operator uses high voltage wiring or the control circuit is not clearly identified, have the work performed by a qualified gate or commercial door technician.
It identifies an MMTC PBS series interior surface-mount station with FORWARD, REVERSE, and STOP button functions.
No. PBS-3UDS is labeled UP-DOWN-STOP, while PBS-3FRS is labeled FORWARD-REVERSE-STOP.
No. It is a control station for a compatible control circuit, not a motor starter or power switching device by itself.
No. PBS-3FRS is a NEMA 1 interior station and should not be installed where an exterior NEMA 4 or NEMA 4X enclosure is needed.
