Now there is a 1200W induction cooker and a 1200W electric pressure in the kitchen at home

Leakage circuit breaker, that is, leakage protector, is a kind of line when there is current, but the current is less than the design current (generally 20mA or 30m

A, is very small), on the disconnection of the circuit of the device. It is a protective device against electric shock or leakage (to the earth).

As you said, the total power of electrical appliances at home is larger, if your home is installed with an old-fashioned gate knife, it should be a fuse blow, if it is installed with an empty open, it generally can't jump, if the air is jumped, the current of the empty trip is generally several thousand A, such a large current, indicating that a short circuit has occurred (fire, zero phase connection), or the live wire is directly connected to the earth.

Therefore, according to your description, if you install a leakage circuit breaker, you will not be able to solve the problem.

The fault cannot be that the wire is on fire, zero phase or the wire is connected to the earth, otherwise as soon as you reset, it will jump again.

The fault may be that there is an electrical internal circuit fire, zero short circuit, or a circuit element in the line aging and energizing for a long time after the resistance becomes smaller or even 0, resulting in a very large current, or it may be that the insulation isolation layer between the fire wire and the neutral line somewhere in the home line is heated, it becomes not insulated, and generally occurs at the joint.

Only by finding the fault first and eliminating it will this phenomenon not occur in the future.

Your total power is two thousand six, divided by the voltage 220, which is twelve amps, so it is enough to buy about fifteen amps. Don't be too big, too big to protect.

Leakage switches and miniature circuit breakers do not have overvoltage protection. For short circuit and leakage protection, it is recommended to use DZ47LE-32 1P+N C16A 30mA leakage switch. The model you said doesn't have!

Based on your description, it is impossible to tell if the appliance is leaking, short-circuited or overloaded.

If it's a leakage jump, then your connection is useless.

If it's a short circuit or an overload jump turn, then your connection will be able to achieve the effect you said.
