Product Description

The new DAM1-2000 series Moulded Case Circuit Breaker, with modular, intelligent, miniaturization, easy installation, replacement concept, modular intelligent controller, communication function and measurement function, new modular manual mechanism and new modular electric mechanism, the core electric mechanism after hundreds of thousands of market rigorous assessment and practical application of the framework of the same organization, The contact system has no cross section from the incoming line end to the outgoing line end, so as to achieve better breaking and short-time resistance to current and temperature rise. The arc extinguishing chamber adopts high-density cascade grid and double extinction

The control technology of the arc chamber ensures the reliability of current breaking. Switch installation: fixed and drawer type DAM1E-2000 series Moulded Case Circuit Breaker (hereinafter referred to as circuit breaker), rated insulation voltage of 1000V, Suitable for AC 50Hz/60Hz, rated working voltage AC3801400/415V, AC500V, AC660/690V, AC800V, rated working current 800A, 1000A, 1250A, 1600A, 2000A circuit, used to distribute power. In addition to overload long delay inverse time limit, short circuit short delay fixed time limit, short circuit short delay inverse time limit, short circuit instantaneous, grounding, overload and alarm, alarm not trip function, can protect the line and power equipment from damage, It also has the current, voltage, power, power frequency, life, opening and closing state, operation times and other information of the feedback product to the host computer or other energy efficiency management system, which is used for the detection and monitoring of the circuit breaker, reducing the operation and maintenance cost of the power grid, and providing the necessary data for the future energy efficiency system.

DAM1Z-2000 series Moulded Case type circuit breaker (hereinafter referred to as circuit breaker), rated insulation voltage is 1200V, suitable for rated working voltage DC500V(2P series), DC60OV(2P series), DC750V(3P series), DC1000V(4P series), DC1200V(4P series), In the circuit with rated working current 800A.1000A, 1250A, 1500A, 1600A, 2000A, it is used to distribute electric energy, and protect the overload, short circuit, and undervoltage (with undervoltage trip device) of the line and power supply equipment.

Conforming to the standard :IEC60947-2, GBIT14048.2.
