SIEMENS 3VL9563-7DE30

SIEMENS 3VL9563-7DE30 is a rugged auxiliary & alarm contact accessory for Siemens SENTRON 3VL series MCCB. The auxiliary & alarm contact accessory is plug-in fitted onto VL630 circuit breaker, including 1 set auxiliary contact and 1 fault alarm contact. This auxiliary & alarm contact accessory feeds back breaker ON/OFF state and short-circuit/trip fault signal to PLC, alarm panel or vessel monitoring system. The auxiliary & alarm contact accessory adopts vibration-resistant construction, suitable for industrial and marine low voltage switchboard cabinets.

This accessory provides breaker status & fault signal feedback logic control for low voltage power monitoring. The breaker status & fault signal feedback logic control outputs dry contact signal to indicate closed or open breaker state. The breaker status & fault signal feedback logic control triggers dedicated alarm signal once breaker trips due to overload or short-circuit. The breaker status & fault signal feedback logic control works independently of main breaker power contacts. The breaker status & fault signal feedback logic control enables remote status viewing and fault recording for power distribution automation.

This SIEMENS spare is an essential LV breaker auxiliary signal spare for 3VL switchboard maintenance. The LV breaker auxiliary signal spare can replace faulty 3VL9563-7DE30 contact assemblies directly. The LV breaker auxiliary signal spare meets IEC international electrical safety specifications. The LV breaker auxiliary signal spare is widely applied on factory, petrochemical and marine vessel low voltage power distribution panels.

SIEMENS 3VL9563-7DE30 auxiliary + alarm contact module is dedicated accessory for SENTRON 3VL VL630 MCCB. It transmits breaker running status and trip fault signals to control and alarm system, performing reliably under humid, vibration marine machinery room environments.
