30
amp, 2-pole, open frame power relay with enclosure SPDT relay.... different from DPST contactor. Both perform same job. Both have 2 sets contacts. Open frame relay SPDT has extra set contacts so a second load can be turned on-off exactly opposite from off-on other load.

Off peak Home
automation OFF peak Use any zwave, wifi, insteon, or programmable timer rated for inductive load. Connect to DPDT 30-40 amp open frame power relay. Or use on-delay timer, off delay timer, cycle timer, twin timer etc.  Magnecraft relay with NO NC terminals 120 volt coil or 24 volt coil Buy from my affiliate links Magnecraft box and cover  Magnecraft

 Larger imageToggle between car charger and water heater or pump, or any 240 volt load. Use any 15 amp timer, home automation module ... or ordinary 15 amp household toggle switch. Switch or timer or automation turns the relay on or off. When relay is on, then the NO terminal sends power to car charger. When relay is off, the NC contact sends power to pump, motor, water heater etc. |
