Thermal Magnetic MCCB TDK5
Scope of Application
TDK5 series molded case circuit breaker(hereinafter referred to as circuit breake)with rated insulation voltage of 1000V is suitable for infrequent switching and infrequent starting of motor in circuits with frequency of AC 50Hz,rated workng voltage of 415V and rated working current of 800A. The circuit breaker has the functions of overload,short circuit and undervoltage protection,which can protect the circuit and power supply equipment from damage.
Circuit breaker can be installed vertically (i.e.vertically)or horizontally (i.e.transversely).
Circuit breaker has isolation function,and their corresponding symbols are: 
Circuit breaker products shall comply with the following standards:
IEC60947-1 General
IEC60947-2 Low Voltage Circuit Breaker
IEC60947-4-1 Electromechanical Contactors and Motor Starters
IEC60947-5-1 Electromechanical Control Circuit Electrical Appliance
