White-rodgers 90-342 Dpdt Power Relay 2 Pole 208 240V

Product Description

The WHITE-RODGERS 90-342 is a double-pole double-throw (DPDT) electromechanical relay designed for switching power loads in HVAC and light commercial control applications. Built to Type 91 specifications, it operates on a 208/240 VAC coil and provides two sets of power-rated contacts in a DPDT configuration. This relay is typically installed by HVAC technicians and electricians as part of control circuits in heating, cooling, or ventilation equipment where reliable load switching at line voltage is required.

The 90-342 is suited for residential and light commercial HVAC systems where 208/240 VAC control coil operation is needed. It fits into applications such as multi-stage air handlers, heat pumps, electric heat sequencing, and fan or compressor staging circuits. Its DPDT contact arrangement allows it to handle two independent load circuits simultaneously, making it useful wherever two switched outputs must be controlled from a single coil signal.

Key Features

• DPDT contact configuration provides two independent switched load paths
• 208/240 VAC coil voltage compatible with standard line-voltage control circuits
• Type 91 relay construction for HVAC control panel and load-switching use
• Two sets of power-rated contacts for simultaneous multi-circuit switching

Compatibility

Designed as an OEM-style replacement relay for HVAC control panels and equipment requiring a 2-pole DPDT relay with a 208/240 VAC coil operating on Type 91 specifications.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed electrician. Disconnect and lock out all power to the control panel or equipment before removing or installing this relay. Verify coil voltage and contact ratings match the application requirements before energizing. Follow applicable NEC guidelines for line-voltage control wiring in HVAC equipment.
