YLM30series Moulded Case Circuit Breaker is one of the new circuit breakers designed and developed by the company synthesizing the international vanguard technology. Its fixed isolation voltage is 800V (YLM30-63 is 500V), and it applies to exchanges 50Hz, fixed working voltage 690V and below, the fixed operating current to the 800A power distribution lattice circuit. It is used to assign the electrical energy and protect line and the power equipment from the overload, the short circuit, owe breakdown voltage damages and so on. At the same time it can protect electric motor from starting infrequently, the overload, the short circuit, owe the voltage.
The circuit breakers are divided into L (standard type), M (high breaking), and H (high breaking) according to its fixed limit short circuit breaking capacity. It has small volume, high short circuit breaking capacity, and short arc over, disconnector and vibration resistance. It is users’ ideal product.
