Acti9 OF auxiliary contact, 1 changeover (1 CO), bottom connection terminals A9N26904

Acti9 Auxiliary Contact – Expand Installation Functionality

This modular iOF auxiliary contact from Acti9 is a reliable solution for remotely monitoring the status of residual current circuit breakers (RCCBs) or overcurrent circuit breakers. It allows you to transmit information about the on/off status of a circuit, which is particularly useful in building automation systems, remote monitoring, and situations requiring additional confirmation of the device's operating status. Compact dimensions (9mm wide) allow for easy integration with existing installations without taking up much space in the distribution board.

Versatility and Compatibility

The iOF auxiliary contact is designed to work with Acti9 circuit breakers, both RCCBs with overcurrent protection and overcurrent circuit breakers. This allows it to be used in a wide range of applications – from protecting lighting and socket circuits to protecting more demanding devices. Its versatility makes it an ideal choice for both new and modernized commercial and residential buildings. The ability to configure the contacts as normally open (NO) or normally closed (NC) provides flexibility in adapting to specific application needs.

Installation and Connection – Simple and Fast

Installing Acti9 auxiliary contacts is extremely easy – it is done on a standard DIN rail, ensuring quick and trouble-free installation. Screw terminals allow connection of wires with a cross-section from 0.5mm² to 2.5mm² (rigid) and 1.5mm² (flexible with ferrule), ensuring a secure and durable electrical connection. This makes it easy for both electricians and automation system installers to integrate this contact into the existing infrastructure. Rated insulation voltage Ui up to 500V and a high level of protection IP20 guarantee safe use in various environmental conditions.
