Undervoltage release Acti9 iMN-230 220240 VAC A9A26960

Undervoltage Release Acti9 iMN-230 – protection against uncontrolled restart

This Acti9 iMN-230 undervoltage release, designed to work with iC60, iID, iDPN Vigi and iSW-NA series circuit breakers (MCBs), provides effective protection against the restart of devices after a voltage drop. Its operation is based on the immediate disconnection of the circuit in the event of a power supply voltage drop, minimizing the risk of damage and ensuring safety. This solution is particularly useful in installations powering several machines, where uncontrolled start-up after power restoration could lead to overloads.

Functionality and application

The iMN-230 release is an auxiliary element mounted on a DIN rail, which simplifies its installation in standard electrical panels. Thanks to a wide range of control voltage (220…240 VAC), it is compatible with most installations. The device has an activity indicator that informs about its operating status. It can also be used with a normally open button for emergency stop. The width of the device is only 1 module (18 mm), which allows for optimal use of space in the switchboard.

Key features and benefits

• Protection against restart: Prevents automatic start-up of devices after power returns, protecting them from damage caused by sudden load.
• Compatibility: Designed to work with popular Acti9 series circuit breakers – iC60, iID, iDPN Vigi and iSW-NA.
• Easy installation: DIN rail mounting simplifies integration with existing electrical infrastructure.
• Compact dimensions: 1 module width allows for efficient use of space in the switchboard.
• Operating status indication: Activity indicator facilitates monitoring of the release operation.
• Universal control voltage: 220…240 VAC range ensures compatibility with most electrical networks.
• Compliance with standards: Meets the requirements of IEC/EN 60947-5-1 standard, guaranteeing safety and reliability.

It is worth remembering that this release does not have a residual current device self-test function. It is a dedicated solution for protection against voltage drops, not for detecting short circuits or leakage currents.
