Alarm switch contact SS2 125-1600AF 004671144

Signaling accessory for ETIBREAK power circuit breakers

The SS2 changeover alarm contact is a key internal accessory for the ETIBREAK 2 series power circuit breakers, enabling effective signaling of the device status in automation systems and electrical installation monitoring.

Design and technical parameters

The device is equipped with one changeover contact with a rated operating current of 3 A for AC-15 at 230 V, ensuring reliable transmission of control signals in typical industrial applications. The electrical connection is made via screw mounting, guaranteeing a durable and secure connection of installation wires.

The contact operates in a changeover configuration, meaning it can change the signal state—simultaneously providing normally open (NO) and normally closed (NC) functionality depending on the position of the circuit breaker mechanism.

Application and compatibility

The accessory has been specifically designed for ETIBREAK 2 power circuit breakers within the current range of 125-630AF, making it a universal solution for most switchgear applications. Installation is performed laterally directly into the circuit breaker body, and the design allows for use in both load break switches and standard power circuit breakers.

The SS2 alarm contact is ideal for emergency signaling systems where it is necessary to monitor the position of the tripping mechanism and generate alarm signals when irregularities occur in the operation of the electrical installation.

Advantages of use and installation

The main benefit of using this accessory is the ability to integrate a monitoring system without the need for external sensors—information about the device status is transmitted directly via the internal mechanism. The design allows for simultaneous installation with other internal accessories such as auxiliary contacts or shunt trips.

The package dimensions are 45×60×30 mm with a weight of only 0.02 kg, which facilitates logistics and storage. The product is available individually as a ready-to-use unit for direct factory or service installation in ETIBREAK 2 devices.
