- Command wiring push-in terminal.
- Power cable box clamp terminal
- Thermal alarm option with led and digital output status
- Load break alarm option with led and digital output status
- Overvoltage protection
- SCCR 100KA
GRS COMMAND SIGNALCONNECTION
The GRS series can be controlled by DC and AC logical signals managed through push-in connectors for a faster and easier connection, even without tools. The ON / OFF status of the static device is always displayed by a green LED on the front panel, for an immediate view of its operation.
DIAGNOSTICS AND ALARMS
The GRS series offers diagnostic information with alarm outputs. A thermal alarm triggers if heat exceeds a critical level, indicated by a yellow LED. It cuts power and activates the alarm output. Absence of current (for DC models) is shown by a red LED and activates the alarm. Alarm status is remembered, and it resets when conditions normalize, or the auxiliary power supply is cycled.
