White-Rodgers 24A07E-1 Relay

The White-Rodgers 24A07E-1 is a 208V electric heat relay engineered for precise control of resistive heating loads in residential and commercial applications. As a Level-Temp silent operator, this unit integrates a self-contained transformer, allowing a standard low-voltage 2-wire thermostat to manage line-voltage equipment like baseboard heaters and wall-insert units. The thermal design features a built-in 45-second time delay for both "on" and "off" cycles, which prevents rapid cycling and reduces stress on the electrical system. This SPST normally open relay utilizes a skeleton construction (no enclosure), providing maximum mounting flexibility with universal break-off mounting tabs for conduit hub or screw-mount configurations. Designed to handle high inrush currents, this 208VAC 60Hz relay is a reliable solution for practitioners looking to consolidate multiple circuits under a single control point while maintaining silent, snap-action switching performance.

• Silent Operation: The Level-Temp technology ensures quiet switching, making it ideal for living spaces where mechanical contactor noise is undesirable.
• Integrated Transformer: Simplifies installation by allowing direct connection to low voltage thermostats without requiring external 24V power sources.
• Sequenced Performance: The 45-second on/off delay provides atmospheric comfort by preventing the abrupt temperature swings often associated with line-voltage controls.
• Versatile Mounting: Featuring skeleton construction and break-off tabs, it adapts to various cabinet or junction box layouts.
• Dual Load Capability: Capable of controlling separate loads, providing flexibility for larger heating zones.

Can this relay be used on 240V circuits?
No. The 24A07E-1 is specifically rated for 208VAC. Because it contains a self-contained transformer, the input supply voltage must precisely match the 208V rating to prevent component failure.

What causes a relay like the 24A07E-1 to fail?
Common failure points include pitted contacts from excessive arcing or a burned-out bimetal heater. If the relay fails to close or provides intermittent heat, technicians should check for 208V at the line-side and verify the thermostat is drawing the correct 0.2A anticipator current.

Does this unit require a specific mounting angle?
This relay features a non-critical mounting angle, meaning it can be installed in any orientation within an appropriate enclosure or furnace cabinet without affecting the thermal delay timing.
