Resideo by Honeywell RC840 Electromechanical Relay for Electric Heating Applications

The Resideo RC840 is an electric heating relay without transformer designed for 120V/208V/240V/277V/347V applications to control line voltage resistive loads from a low voltage thermostat. This easy-to-install electromechanical relay features instant activation, providing improved temperature control and comfort.

Key Features:

• SPST contact form with 24 VAC coil, 60 Hz operation
• Current ratings: 16A @ 120VAC, 13A @ 208VAC, 12A @ 240VAC at full load
• Motor load capacity: 0.8 HP @ 120VAC, 1.0 HP @ 208VAC, 1.5 HP @ 240VAC
• Compatible with 2-wire and 3-wire 24V thermostats with epoxy-soundproofing for quiet operation and 12 AWG terminal wires
• Operating temperature range: -20°C to 60°C (-4°F to 140°F)
• UL and cUL approved

Ideal for controlling baseboard heaters, convectors, heating ceilings, and duct heaters with conventional 24VAC thermostats. The terminal board connection enables easy installation, and low current consumption allows multiple relays to be controlled by a single thermostat. Direct replacement for any brand name relay. Note: Separate transformer required (not included).
