3-Pole Contactor
(120V AC Coil)
1. High-Amp Contactors
High amp contactors and relays are operated by controlling the power to the magnet coil. When the magnet
is energized, high current/voltage is switched on from a breaker panel to load receptacles.
2. HVAC Control Signals
24VAC HVAC control signals may be operated by dry contact. Use jumper wires for relays with a common
source connection.
3. 120V Outlets
Contacts can switch up to 10A to directly feed receptacles or other 120V equipment.
4. Solenoid Valves
24VAC irrigation and gas valves can be controlled by switching power supplied by a step-down transformer.
24VAC is safer and more common than line-voltage for water/irrigation solenoids.
