Key Specifications:

• Coil Voltage: 24V AC, 50/60 Hz
• Contact Configuration: 2-Pole DPST (Double Pole Single Throw)
• Current Rating: 30 Amp resistive load
• Contact Type: Non-reversing
• Includes 4 terminals and 4 mounting screws
• Non-positional mounting design for flexible installation

Universal Replacement Capability:

This contactor serves as a direct replacement for multiple OEM part numbers including GE 3ARR8E4, Mars 18001, Honeywell R850B1146, Packard C18001, and White Rodgers 90-230. It has been used in HVAC applications since the 1960s and provides proven reliability for furnace and air handler motor control.

Applications:

Ideal for residential and light commercial HVAC equipment, the SMC11 controls electric heat systems, air conditioning units, and blower motor circuits. The magnetic contact engagement ensures consistent performance through repeated heating and cooling cycles while minimizing electrical resistance and extending system life.
