Universal MCCB Molded Case Breaker / 12 Volt 100 Amp Circuit Breaker

 

What is the details of our circuit breaker?                                                                                       

 

1. Applicable for 50/60Hz

 

2. Rated current up to 1600A, rated voltage up to 690V, rated breaking capacity up to 65kA

 

3. Thermal overload release and magnetic short circuit release

 

4. Modularization and applicable for two switch interlocking.

 

5. Optional breaking capacity and pole number, fulfills all kinds of application.

 

6. Protect low voltage power distribution from the damage of over-load, short-circuit and under-voltage.

 

7.  Used for unfrequent motor start and protect from motor over-load, short-circuit and under-voltage.

 

 

How about the performance of our MCCB?                                                                                    

 

Long delay setting range IR=(0.4~1.0)×InOFF (OFF close long delay)

Operation
feature
I≤1.05IR (motor protection I≤1.0IR ),
more than 2h's in-operation (when In≤63A, more than 1h's in-operation)
I≥1.3IR (motor protection I≥1.2IR ),
less than 2h's in-operation (when In≤63A, less than 1h's in-operation)
Operative time (s) Time setting value (s) 12, 60, 80, 100
Characteristic curve TR =(2IR/ I)²×IR
Time accuracy ±10%

 

Note: when setting current, instantaneous current value Ii should bigger than short delay current setting value Isd, should bigger than long delay setting value IR, that is IiIsd IR. If long delay, short delay and instantaneous setting values are overlapping,priority should be:

instantaneous release→short time delay release → long time delay.
