High Quality Elevator Contactor 3TF48 22-0XF0 with Main Circuit Switching and Auxiliary Contact Linkage

New Elevator Spare Parts DC Contactor High Quality Original Elevator Electromagnetic AC Contactor 3TF48 22-0XF0

Main circuit switching: When the coil is energized, the three main contacts are closed, connecting the three-phase power supply to drive the load; when de-energized, the spring resets and disconnects the circuit, suitable for AC-3 operating conditions (frequent starting and stopping of motors), with a rated current suitable for medium and high-power motors.
Auxiliary contact linkage:  Includes 2 normally open + 2 normally closed auxiliary contacts for control circuit self-locking, interlocking, or signal feedback (such as fault alarms, operating status indication), ensuring reliable control logic.
Safety protection coordination:  Works in conjunction with thermal overload relays (such as the 3UA series), PLC/inverters to achieve rapid disconnection in case of overload, phase loss, short circuit, and other faults, preventing equipment burnout and safety accidents.

Long-distance and frequent control: Adapts to the remote control needs of elevator machine rooms, shafts, and cabins, supporting high-frequency start-stop operations (such as elevator door motors and escalator drives), with a mechanical lifespan of millions of cycles.
Arc suppression and insulation: Built-in resin arc suppression cover quickly extinguishes arcs during disconnection, with a rated insulation voltage of 690V, compatible with mainstream 380V elevator electrical systems, improving operational safety.
