Signal contact 1S 9 mm wide plug-in for flush mounting collective alarm with contacts LA+LB – 2CCS500900R0216

The auxiliary and signal contacts are mounted on the left side of the protection devices; on circuit breakers, they can also be mounted on the right. For auxiliary and signal contacts that are supplied via SMISSLINE auxiliary busbars LA or LB, a version with integrated contacting is available. In addition, conventional supply via terminals is also possible. The auxiliary contact operates analogously to the main contacts. The signal contact only operates in the event of an electrical trip. This can be simulated with the test button. After each trip, the signal contact must be reset to its initial position using the orange reset button. The auxiliary and signal contacts with 1NO and 1NC and the connection support point are delivered with a contacting piece for direct connection to a Smissline TP base. The collective alarm signal contact, like auxiliary and signal contacts with 2NO and 2NC, have two contacting pieces. Collective alarm signal contact with contacting via auxiliary busbars LA, LB: with this add-on element, a cost-effective collective alarm solution can be realized without additional wiring.
