Emerson SureSwitch™ Relay

Model # 49P11-843

Product description

Emerson SureSwitch™ relay replaces the function of a contactor; and adds a short-cycle timer, brownout protection and a reliable, long-life sealed switch. Designed to fit in the space of a traditional mechanical contactor, SureSwitch relay is a universal electronic upgrade.


SureSwitch relays can be used to upgrade 30 Amp compressor contactor applications. Backed with a 5-Year warranty, SureSwitch should last as long as the serviced equipment. SureSwitch is an ideal add-on with new preventative maintenance contracts or for jobs where repeat failures are likely due to exposure to insects or inconsistent power.
