\n<\/h2>\n

WLM7DC series Moulded Case Circuit Breaker is designed to distribute power and protect the circuit and power equipment against overload in solar system.
\nIs a new type of product, developed and manufactured by Adopting international advanced technology
\nIt is supplied with rated insulation voltage 1000V and used for circuit of\u00a0 50Hz \/60Hz, rated operation voltage DC 1000V or below rated operation current up to 800A for infrequent changing over and starting of the motors. Equipped with the protection devices for over-current, short circuit and under voltage, the product is capable of preventing damage of circuits and supply units. The product conforms to IEC60947-2 standard.<\/p>\n
