Moulded Case Circuit Breaker (Electronic Adjustable)

Characteristics of Moulded Case Circuit Breaker (Electronic Adjustable)
1. ZLM30RE moulded case circuit breaker (electronic adjustable) is usually used in low voltage distribution network where the frequency of circuit is AC 50Hz, rated working voltage is 690V, and rated working current is 800A.
2. Our moulded case circuit breaker (electronic adjustable) can be fitted with many accessories, such as under-voltage trip, shunt trip, auxiliary switch motor operated mechanism and rotary handle, among others.
3. This series of moulded case circuit breaker can offer long time delay overload protection, short time delay short circuit protection and instantaneous short circuit protection, on the condition that users have set required parameters of protection function with DIP switch.
4. Besides, ZLM30RE series breaker also has many other functions, such as residual current protection, ground-fault protection, thermal simulation protection, over current indication, load current indication, and digital current analysis, etc.

Application of Moulded Case Circuit Breaker (Electronic Adjustable)
This moulded case circuit breaker (electronic adjustable) is widely used for low voltage distribution networks, with a rated insulation voltage of 690V, a rated working voltage of 400V (or lower), a rated working current of 800A and AC 50HZ.

Feature of Moulded Case Circuit Breaker (Electronic Adjustable)
1. This breaker can be installed with accessories, such as Undervoltage trip ,shunt trip ,Auxiliary switch motor operator mechanism ,rotary handle and so on .
2.This breaker has the protection of overload long time delay .short circuit short time delay and short circuit instantaneous user can set required protection characteristics (just need to set parameter of protection function with DIP—switch )
3.This breaker also has the function of ground—fault and thermal simulation protection ,over current indication ,load current indication and digital current analysis in order to carry out higher grade of protection function .
4.ZLM30REL series has residual current protection function .
