SureSwitch Universal Electronic Upgrade for Mechanical Compressor Contactors (For up to 5 ton/40A, 1 or 1.5 pole applications)

Allied Part No: 7584911
Manufacturer: White Rodgers
Additional Information: 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 also provides advanced features for HVAC troubleshooting and system reliability: Line-Voltage Brownout Protection, Short Cycle Protection, Random Start Delay, Lifetime Cycle Count. SureSwitch is similar to a 1 1/2 pole contactor, in that only the compressor terminal C is switched. The compressor terminal R is connected by a shorting bar to line input L1, and is energized even when a call is not present.
Ambient Operating Temperature: -40 to 158F (-40 to 70C)
Amperage: 40A
Anti-Short-Cycle Delay: 0s or 180s (selectable) at 60 Hz, 0s or 216s (selectable) at 50 Hz
Compressor Test: 5s at 60 Hz, 6s at 50 Hz
Control (Coil) Voltage: 24 Vac, 50/60 Hz
Humidity Range: 5 to 95% relative Humidity (non-condensing)
Line Voltage: Input 240 Vac, 50/60 Hz
Locked Rotor Amperes: 200A
Overall Dimensions: 2.75"W X 2.38"H X 3.88"L
Product: Contactor Upgrade
