Acti9 Overcurrent Trip Unit – Reliable Protection and Signaling

This Acti9 overcurrent trip unit, designed to work with iC60, iID, iDPN Vigi and iSW-NA series circuit breakers, is a key element of the electrical protection system. This device not only provides effective tripping of the circuit in the event of overload or short circuit, but also offers additional signaling functionality thanks to the built-in auxiliary contact.

This trip unit is particularly useful in applications requiring a quick response to failures and precise control of the circuit status. Its compact design (1 module wide) allows for easy mounting on a DIN rail, which translates to space savings in the switchboard. This makes the installation more transparent and easier to maintain.

Functionality and application

The device acts as a shunt trip with an open/closed (OF) auxiliary contact, which indicates the status of the device to which it is connected. In addition, it has an emergency stop function using a normally open button – when pressed, the associated circuit breaker is tripped. This solution increases work safety and enables a quick response in emergency situations.

The trip unit is adapted to work both in alternating current (AC) circuits with a voltage of 100-415V and direct current (DC) 110-130V. The rated switching current is 6A, making it suitable for protecting various loads. The ability to connect up to four main contacts with a maximum current of 63A expands its range of applications.
