Automatic Transfer Switch  

Model and meaning

Normal working conditions

Ambient temperature：-5~+40℃， and average temperature in 24 hours below+35℃ (except for special orders) 

Elevation of installation site：2000m.

Relativehumidity：not exceeding 50% at the maximumam bient temperature of+40℃ With lower temperature，higher humidity would be permitted，but the lowest average  temperature in a month not exceeding 90in that month， and giving consideration to thedews on the goods surface， which would appear due to temperature change.

Pollution protection ：3 grade

The breaker should be putin the place where there isnt any explosive medium and conductive dust and no gas， which would corrode metal or des toy the insulation.

Structure and properties

RP6isacrtical 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，there-transfer process returns the load circuit to the normal power source

1) The setting is formed with two sets power-operated operation mechanism circuit breakers and mechanical interlocking， fuse， wiring terminal.

2) Two-set circuit breakers have electric interlocking and mechanical interlocking double protections to prevent the two-set circuit breaker close on at the sametime.

3) The settings uitsfor220V working voltage(circuit breaker rated working voltage),control the power pass the case， frame board control pushbutton(user self-prepared and connect to) directcontrol two sets power operated operation mechanism to carry out the power reliable switchover.

4) Suitable for general manual work control occasion， simple structure， lowcost
