TKDM1 Molded Case Circuit Breaker
The TKDM1 molded case circuit breaker is usually used to distribute power and to protect lines and power equipment from the damage of overload, under-voltage, short circuit, and other faults. It is applied in the power system with the rated frequency of AC 50Hz or 60 Hz, the rated insulation voltage of 800 V, the rated working voltage of 690 V or below, and the rated working current up to 800 A. The product with rated current of 630A or below can also be used for motor protection.
