Description
Dimensions
Internal connection diagrams
A module suitable for all double pole versions of type 3120 to trip the
main switch/circuit breaker mechanism in the event of loss of voltage.
When the voltage is restored the rocker switch must be reset to
reconnect the load, thereby avoiding the safety hazards associated
with automatic re-starting of machinery.
Note:
Basic unit 3120-...-H7 or -G7 screw terminals necessary.
Ordering information
Machines such as power tools, industrial equipment and domestic
appliances where automatic restart after restoration of power could be
dangerous (EU Machinery Directive)
