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.

  • Multi-volt coil works with all common coil voltages
  • 5x traditional contactor life
  • Totally sealed switch keeps out ants, pests and debris
  • Microprocessor control inhibits arcing that cause welding and pitting
  • Line voltage brownout protection and short cycle timer provide compressor protection
  • Zero chatter latching relay
  • Heavy-duty lug connectors
  • 5-year limited warranty
  • Four-hole mounting matches mechanical contactors
  • Tri-color LED with compressor test and cycle count by pushbutton
