The high rated insulation voltage of 690V enhances its safety profile, making it a dependable choice for complex industrial switching applications where consistent signal transmission is critical.

Suitable for

Industrial automation control circuits
Signal switching in electrical panels
Motor control center auxiliary functions
Building management system integration

When it may not be suitable

This device is intended for auxiliary control circuits and is not suitable for switching high-power main loads directly. It should not be used in environments exceeding the specified temperature limits or in applications requiring DC coil operation.

Key specifications

Rated current: 10A
Contact configuration: 3 NO and 1 NC
Coil voltage: 24V AC
Rated insulation voltage: 690V
Operating temperature: -25 to 50 °C
Dimensions: 45 mm width, 57 mm depth, 58 mm height

How to use

The contactor is designed for standard DIN rail or panel mounting. Ensure the power supply is disconnected before installation. Connect the 24V AC control signal to the coil terminals and wire the auxiliary contacts according to your specific circuit diagram. Verify all connections are secure and that the voltage matches the coil rating before energizing the system.

What to consider before purchase

Verify that your control system provides a 24V AC signal.
Ensure the contact configuration (3 NO, 1 NC) meets your circuit requirements.
Check available space in your enclosure against the device dimensions.
Confirm the ambient operating temperature of your installation site.

Usage recommendations

Always ensure that the electrical load connected to the auxiliary contacts does not exceed the 10A rating to prevent premature wear or failure of the internal components.
