Maximum operational voltage: 500 V
Series: SIRIUS ACT
Mounting type: Modular snap-on
How to use
The contact element is designed for simple installation by snapping it directly onto the holder of the SIRIUS ACT command device. Ensure the power supply is disconnected before installation to maintain safety. Once the actuator is mounted in the panel cutout, align the contact element with the holder and press until it clicks into place. Wiring is performed via the integrated terminals, ensuring that connections are tightened to the specified torque to maintain reliable electrical contact.
What to consider before purchase
Verify compatibility with your existing SIRIUS ACT actuator or holder.
Ensure the 1 NC contact configuration meets your specific circuit logic requirements.
Check that the operational voltage and current ratings align with your control system specifications.
Usage recommendations
Always verify that the contact element is securely locked into the holder before commissioning. Regularly inspect terminal connections for tightness and ensure the environment remains within the specified temperature and humidity limits to guarantee optimal performance.
