Application:
The moulded case circuit breaker is mainly used in distribution network of AC50Hz or 60Hz, rated voltage up to 690V, rated working current up to 1600A to distribute electric power and to protect the line and the equipment from being damaged due to overload .short circuit and under-voltage.
lt can also be used for unfrequent motor start and for motor overload,short circuit and under voltage protections
Standard: I EC 60947-2.

1.3 Arm contact
1.4 Auxiliary contacts
1.4.1 Auxiliary contact ,rated current of warning contact
1.4.2 Power performance and the corresponding test conditions of auxiliary contacts
1.4.3 Auxiliary contact in the non-normal conditions connected and the breaking capacity
Note: the above two table
1. 6Pe=T0.95 empirical formula, Pe use'W' for the units, T0.95 in milliseconds
2. When the circuit breaker performance is less than the total number of 6050 times, while the aux-iliary contact's power performance times is equal to the total breaking performance times.
3. Operating frequency and the power time are allowed to with the line of main circuit breaker.
