White-rodgers 49m11-843 Multi-v Contactor

Product Description

The WHITE-RODGERS 49m11-843 is a SureSwitch Multi-V contactor designed for switching loads in HVAC systems where voltage requirements vary across installations. Contactors in this class handle the high-current switching function that energizes compressors, condenser fan motors, and other inductive loads. The Multi-V designation indicates compatibility across a range of coil voltages, making this unit suitable for a broad set of residential and light commercial applications. Licensed HVAC technicians install and replace contactors as part of routine system service and compressor circuit diagnostics.

This contactor is appropriate for use in air conditioning condensing units and heat pump systems where a reliable, multi-voltage switching device is required. The SureSwitch product line is associated with Copeland-compatible HVAC applications, and the 49m11-843 part number is used in systems requiring a drop-in contactor replacement. Installers should verify coil voltage and pole configuration against the existing unit's wiring diagram before installation.

Key Features

• Multi-V coil design accommodates a range of control voltages across compatible systems
• SureSwitch construction provides reliable make-and-break switching for inductive HVAC loads
• Designed for compressor and condenser fan circuit switching in condensing units
• OEM-style replacement form factor for straightforward field serviceability

Compatibility

Designed as an OEM-style replacement contactor for residential and light commercial HVAC condensing units and heat pump systems requiring a multi-voltage switching device.

Installation Notes

Contactors are installed by licensed HVAC technicians. Disconnect and lock out all power to the condensing unit at the disconnect block and the main panel before removing the existing contactor. Verify coil voltage rating and pole configuration match the system wiring diagram before installing the replacement. Follow applicable NEC requirements for low-voltage control wiring and line-voltage load terminals.
