The product passed CCC certificate
Excellent current-limiting characteristic
B42 series miniature circuit breakers have excellent current-limiting characteristic, which is superior to that specified for Class III in IEC60898 standard. This means that, in case of a short circuit, B42 series Miniature circuit breakers can minimize the heating effect of the cable and
Fault point, which can not only improve the safety of the electrical system and reduce the effect of the fault on the system and equipment, but also reduce the impact of short circuit on the breaker itself, thus greatly increasing the electrical life of the breaker
excellent breaking characteristic
The breaking ability is the main and also the most important electrical index for circuit breakers. The reliability of a circuit breaker at an extreme interruption condition is related to the safety of the low voltage system, equipment or even persons. Meanwhile, the breaking characteristic is also an important criterion for judging the technical level, manufacture process and product quality of circuit breakers
The improvement of B42 series miniature circuit breakers in rapid interruption and arc-extinction techniques has greatly raised the interruption ability and also the safety and reliability of B42 series products.


Isolation function


B42 series miniature circuit breakers conform to the supplementary safety provisions for the breakers with isolation function in IEC60947-2/GB14048.2 and fully satisfy all the requirements on isolating the electrical devices.
Impulse withstand voltage, 6KV
The arrow on the lever indicates that the contacts are in a real interruption status.
Lockable Off-position
Good shock resistance

Notes: The order must specify the pole number, rated current, rated voltage, trip type and number of breakers.
For example: If a client wants ten circuit breakers of 32A Class 3 C-type characteristic, he may specify on the order
as: TAYEE 42-63/3P, C32, 10 units.Notes: The order must specify the pole number, rated current, rated voltage, trip type or leakage action current and trip number
For example: If a client wants ten circuit breakers of 32A , 4 poles, C-type characteristic, he may specify on the order as: TAYEE
B42LE-40/4P,C32,f?30mA 10 units
