Application

TSM9 moulded case circuit breaker supplied with rated insulation voltage 1000V is used for circuit of AC 50/60Hz, rated operating voltage AC 690V and rated operating current up to 1600A for infrequent changing over and starting of the motors.
Equipped with the protection devices against over current, short circuit and under voltage, the product is capable of preventing damage of circuits and supply units. The product can be used to replace a load switch with isolation function. The products comply with IEC60947-2.
The product is equipped with an intelligent controller with LCD display. Rated operating current, overload setting current, short circuit delay current, short circuit instantaneous current, tripping time, as well as short circuit instantaneous three-stage protection and under voltage protection can be set in advance.
The product is also equipped with RS485 communication interface and MODBUS-RTU protocol, DL/T 645 protocol.
The following indication can be chosen by the users:
Remote signal: breaking closing, tripping, alarm and fault status indication;
Remote control: breaking, closing, resetting;
Telemetry: three phase current and N phase current, grounding current, trip memory
function, and functions such as querying trip recording parameters.
