White-Rodgers 49M11-843 SureSwitch Multi-Volt Contactor 40 Amps Can Replace Single and Two Pole

Emerson White-Rodgers part number 49M11-843

SureSwitch Multi-Volt Universal Contactor

Universal electronic upgrade for definite purpose contactors for air conditioning and refrigeration, with 5x contactor life and completely sealed to keep out insects and debris

SureSwitch is an electronically controlled relay that can be used to replace single and two pole contactors commonly used in air conditioners, heat pumps and other applications. A patented switching algorithm reduces arcing between contact, which nearly eliminates pitting and welding for a longer life. The switching mechanism is sealed to prevent intrusion from insects and other debris.
