The switching capacity is 10kA according to IEC\/EN 60947-2. The DC rated voltage is 300V per pole, rated voltage up to 1200V DC.<\/p>\n<p>JCZS80-DC circuit breaker is available with rated currents of 2A to 80A.<\/p>\n<p>JCZS80-DC DC circuit breaker offer new features, better connection, superior performance and increased levels of security. Its breaking capacity is up to 10kA.<\/p>\n<p>JCZS80-DC DC circuit breaker can be locked (by a padlocking device) in OFF position as a safety measure for removal of the PV inverter<br \/>Since a fault current can flow in the reverse direction to the operating current, the JCZS80-DC Circuit breaker can detect and protect against any bidirectional current.
