27/12/2017· Overcurrent protection is when the fault current in the circuit reaches the action value of the current relay, the current of the current relay is set according to the requirements of the line selectivity.
Isolation Switches Every water heater, air-conditioning and heat pump system shall be provided with an independent isolating switch (lockable) installed adjacent to but not on the unit (at arms length or 1.25 metres). 4.18.1.1 Gas Appliances - Australia only The means of isolation shall be a plug to an accessible switched socket-outlet.
Risk of electric leakage. With 2-3mA passing current, human starts to feel current, but not dangerous even when continued. With 5-30mA passing current, human has trouble breathing or blood pressure rises. Several minutes is the limit. Some 100mA-some A ground fault current causes arc ground fault.

1.C65 DC miniature circuit breaker is mainly used for protection against overload and short circuit under the AC 50Hz/60Hz, reted voltage 230V/400V and rated current from 1A to 63A. It also can be used for non-frequent on-and-off switch operation under normal circumstance.
An overload is a condition at which a motor draws a current above its rated value, for a prolonged period. It is the most encountered fault and can result in temperature rise in the motor winding. Hence the rapid return to normal operation is important. Principle of operation
Usually, a D-type MCB breaker is used for high-power industrial loads like welding machines, x-ray. Type K MCB It has 8-12 times the breaking capacity of the main load current. The …
