Auxiliary contact + auxiliary/signalling contact Acti9 iOF+iOF/iSD, 2-pole changeover (2 CO) A9A26909

Universal auxiliary and signaling contact Acti9

This Acti9 modular auxiliary/signaling contact, catalog number A9A26909, expands the functionality of Acti9 residual current circuit breakers and overcurrent circuit breakers. It allows you to add additional switching contacts to an existing installation, which is useful both during the construction of new and the modernization of existing systems. This makes it easy to monitor the circuit status and integrate with control systems.

Functionality and application

This contact offers two changeover contacts (2 CO) that can be configured as auxiliary or signaling contacts. This means it can be used both to control other devices in the circuit and to transmit information about the status of the circuit breaker - e.g. its disconnection due to a short circuit or overload. This versatile solution is suitable for commercial installations and residential buildings.

• Flexibility: The ability to configure the contacts as auxiliary or signaling adapts the device to different installation needs.
• Compatibility: Designed to work with residual current circuit breakers with overcurrent protection and Acti9 overcurrent circuit breakers (iID, iDPN Vigi, iSW-NA, ARA, iC60, RCA, and also iC40, iC40 ARC, iCV40, iCV40 Vigi ARC).
• Signaling: A built-in mechanical indicator allows for local visual control of the contact status.
• Safety: Compliance with EN/IEC 60947-5-1 and GB/T 14048.5 standards ensures safe use.

Installation and parameters

Installation is on a DIN rail, which facilitates integration with existing switchgear. The contact has screw terminals allowing the connection of wires with a cross-section from 0.5 mm² to 4 mm², both solid and stranded (with ferrules). The rated switching current is 0.1A and the rated voltage is 240V AC/DC. The width of the device is only 0.5 module (9mm), which allows for optimal use of space in the switchboard. The use of high-quality materials guarantees reliable operation for a long time.

The contact function is auxiliary or disturbance signaling contact. It has two changeover contacts and operates under AC/DC voltage. Its width is 0.5 module and the rated switching current is 0.1A at a rated voltage of 240V.

This contact is an ideal solution for installers looking for a universal and reliable element to expand existing electrical installations and for end users who want to increase the functionality of their protection systems.
