Description
SQ3-63A
2P – 220V
Automatic transfer switch
SQ3 is a critical component of any emergency or standby power system. When the normal (preferred) source of power is lost, A transfer switch quickly and safely shifts the load circuit from the normal source of power to the emergency (alternate) source of Power. This permits critical loads to continue running with minimal or no outage. After the normal source of power has been restored, the re-transfer process returns the load circuit to the normal power source.
- The setting is formed with two sets power-operated operation mechanism circuit breakers and mechanical interlocking, fuse, wiring terminal.
- Two-set circuit breakers have electric interlocking and mechanical interlocking double protections to prevent the two-set Circuit breaker close on at the same ti
- The setting suits for 220V working voltage (circuit breaker rated working voltage), control the power pass the cas e, frame board control pushbutton (user self-prepared and connect to) direct control two sets power operated operation mechanism to carry out the power reliable switch over.
- Suitable for general manual work control occasion, simple structure, low cost.
-
Note: power will be interrupted when Switch time<4S
