DC CONTACTORS

DC Contactors for 12 V, 24 V and 48 V Control Circuits

A DC contactor looks like an AC one from the outside, but the arc chamber is different. Direct current never crosses zero, so the arc keeps burning unless a magnetic field pushes it into a chute. The CJX2-Z range has those blowout magnets, which is why it can break DC loads that would weld an AC frame.

Seven frames cover 25 A to 95 A in three-pole format, and the WTH8-16Z and WTH8-63Z add 16 A and 63 A modular units for DIN rail. Coils are available for 12 V, 24 V and 48 V DC control supplies, the voltages used in battery, solar and vehicle systems.

Where the load is inductive, such as a motor or a solenoid, check the DC rating at your voltage rather than the AC rating. Units carry CE and CCC marking.

DC Contactors for 12 V, 24 V and 48 V Control Circuits

DC Contactor Selection

The DC rating depends on voltage as much as current. Poles in series raise the breaking voltage, so a 220 V DC load is not the same job as a 48 V one.

Before you order

Give the system voltage, not just the current. A 48 V and a 220 V DC circuit are different duties for the same frame.
State the control voltage. A 24 V DC coil will not pull in on a 12 V supply, and a 12 V coil on 24 V will overheat.
Check the load type. Motors and solenoids store energy; fit a flyback diode or an RC suppressor across the coil to protect the control circuit.

Send the system voltage, current and control supply, and we will confirm the frame and the coil code.

Voltage Decides the Frame

48 V and 220 V DC are different duties at the same current. The arc chamber, not the amp rating, sets the limit.

Coil Mismatch Is the Usual Failure

A 24 V coil will not pull in on 12 V, and a 12 V coil on 24 V overheats. The coil code is confirmed on the order.

The Load Can Bite Back

Motors and solenoids store energy. A flyback diode across the coil protects the switch or relay that drives it.

A relay switches a small control load, usually a few amps. A contactor is built for a power circuit, with heavier contacts and an arc chamber, and is rated for tens or hundreds of amps. A DC contactor used as a relay is normally switching a relay coil or a small load, not the main battery current.
