Automatic circuit breaker EKF DA63M-25-30 25A, 6ka

Purpose of the

circuit breaker of the automatic differential current is a mechanical switching device designed to turn on and disconnect currents under normal operating conditions, as well as the opening of contacts in the case when the value of the differential current reaches a given value under certain conditions.

Scope

is used in electric networks of domestic and industrial use of low voltage, to protect the person and equipment of various purposes from leakage and short circuits.

The principle of action

the executive mechanism, usually consisting of a spring drive, a trigger and a group of power contacts, open an electric circuit. As a result, the defended diff. The electrical installation is de -energized. For the exercise of periodic monitoring of serviceability (performance) of DIF. The machine is provided for a testing circuit. When pressing the “Test” button, a disconnecting differential current is artificially created. The triggering of the RCD means that it is generally regular.

The standard set includes the device itself
