Industrial reversing contactor for motor control

The Eaton XTCR018C21A is a three-pole IEC magnetic contactor rated for 18 amps inductive and 40 amps resistive load at 120 volts AC coil voltage. It provides reversing capability for three-phase motor applications up to 5 horsepower at 240 volts AC. The unit mounts on DIN rail or panel and uses screw terminals for secure wiring connections. Its frame size C design suits industrial automation panels and control circuits.

Sustained load behaviour

Under continuous operation the contactor maintains its rated inductive and resistive currents without derating when installed per its enclosure rating of none. The coil operates on 110 or 120 volts AC and the four auxiliary contacts configured as two normally open and two normally closed support interlocking and status feedback in the control circuit. Heat dissipation relies on the open-frame construction and ambient airflow within the cabinet.

Verify coil voltage and mounting before ordering

Confirm that your control supply delivers 110 or 120 volts AC to match the coil specification. Ensure the panel or DIN rail space accommodates the overall height of 4 inches and width of 5.5 inches. Check that the screw terminal wire gauge suits your installation and that the reversing function aligns with your motor starter logic. The product includes no enclosure so plan for appropriate protective housing.

Questions about this item

Does the 120 V AC coil generate noticeable heat or noise when the contactor runs continuously?

The coil is rated for 110/120 V AC operation; normal coil warmth occurs during continuous energisation, and the unit has no moving parts that produce audible noise beyond a faint hum.

What auxiliary power or control wiring must already be in place for the 2NO auxiliary contacts to function?

The contactor provides four auxiliary contacts in a 2NO configuration that connect via screw terminals; a compatible 120 V AC control circuit and wiring to those terminals are required.

Will this reversing contactor coordinate with an existing 240 V AC three-phase motor starter rated for 5 hp?

Yes, the contactor is rated 5 hp at 240 V AC three-phase and 18 A inductive load, matching a 5 hp motor starter of the same voltage and phase.
