Schneider Electric (Barber Colman) MA-419 S/R 2-Position Electric Actuator 240V

The Schneider Electric (Barber Colman) MA-419-500 is a 240-volt motor starter with an auxiliary switch. This electromechanical device is ideal for a variety of applications in industrial automation and HVAC (Heating, Ventilation, and Air Conditioning) equipment since it integrates an SPDT (Single-Pole, Double-Throw) auxiliary switch and a single-phase motor starter into a compact unit. Consider a single part that does two things for your system: it manages a motor and adds another switching function. The MA-419-500 uses a number of different mechanisms to function. The auxiliary switch works like a tiny relay, and the motor starter engages and disengages the motor using an electromagnet. The starter's coil creates a magnetic field when it is energised, which turns on the motor.
