Shanghai DaDa Electric Co., Ltd. presents the Dam2-400 Circuit Breaker Household Electrical, a reliable and efficient solution for low voltage circuit protection. This molded case circuit breaker, also known as MCCB, is designed for manual operation and offers normal speed action.

The Dam2-400 Circuit Breaker is suitable for a wide range of applications, providing reliable protection against electrical faults. With its fixed type design, this circuit breaker ensures stable and secure performance.

Featuring a rated operating voltage of AC230/50Hz, the Dam2-400 Circuit Breaker can operate within a range of 65% to 110% of its rated voltage. This flexibility allows for versatile usage in various electrical systems.

In addition, this circuit breaker is equipped with auxiliary contacts and alarm contacts, providing enhanced functionality and convenience. Please refer to Table 5 for the specific rated values of these contacts.

For added safety, the Dam2-400 Circuit Breaker includes an under-voltage release feature. When the power supply voltage drops below the rated voltage range of 70% to 35%, the under-voltage release ensures reliable circuit breaking. It also prevents the circuit breaker from closing when the supply voltage is below 35% of the rated voltage. Conversely, when the supply voltage exceeds 85% of the rated voltage, the under-voltage release ensures proper circuit breaker closure. Please note that the under-voltage release is rated at AC50Hz, 230V, and 400V.

Furthermore, this circuit breaker includes a pre-paid meter dedicated release. With a rated operating voltage of AC230/50Hz, it operates smoothly within the range of 65% to 110% of its rated voltage. When the Ctrl is cut off, the circuit breaker features a delay of 0.5s to 2s before opening.
