Emerson 49M11-843 SureSwitch™ Multi-Volt Universal Contactor

Description

Emerson 49M11-843 SureSwitch™ Multi-Volt Universal Contactor
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 contacts, which nearly eliminates pitting and welding for a longer life. The switching mechanism is sealed to prevent intrusion from insects and other debris.
SureSwitch is similar to a 1 1 /2 pole contactor, in that L1 only the compressor terminal T1(C) is switched. The compressor terminal T2(R) is connected by a shorting bar to line input L2, and is energized even when a call is not present.
