1000V DC HIGH VOLTAGE MOLDED CASE CIRCUIT BREAKERS,
DC1 SERIES
DC MOULDED CASE CIRCUIT BREAKERS (MCCB) are used for the protection of electrical devices
that operate with direct current. The DC MCCBs are available in 50A-300A with maximum breaking
capacity up to 20kA, which can ensure reliable short-circuit protection of the system. The MCCBs
available in 2P, with nominal voltage of 1000VDC.
FUNCTIONS
• Protection against overloading.
• Protection against short circuit.
• Manual switching control.
• High breaking capacity level.
• Breaking of electrical circuits and control of powerful consumers.
