Circuit breakers with a housing with a line side and a load side and an electronically controlled lock-out lock member coupled to the housing configured to electronically controllably travel between a first position and a second position. In the second position, the lock member is in a lock-out position and prevents the handle from moving to an ON position associated with electrical current conduction and in the first position the lock member is translated to a position that allows the handle to move to the ON position.

An automatic configurable relay and a method for automatically configuring a relay. The relay comprises an input sampling module for coupling to a source to be monitored, the sampling module configured to detect a first value of a parameter of the source to be monitored; and a processing module configured to set a working condition based on the detected first value.

A method for operating an electrical device, including automatically configuring a communication unit following the installation of a new application, wherein: a) the control unit broadcasts a notification of the installation of a new application; b) the communication gateway acquires the list of the types of data to which it is not yet subscribed and then sends, to the control unit, a request to subscribe to these types of data; c) the control unit receives the subscription request and compares the types listed in the subscription request with the types of data generated by the newly installed application; d) the communication gateway updates the accepted or denied subscription status for each type of data for which the subscription request has been accepted or denied during step c).

The current transformer includes a magnetic circuit made of magnetic material that is intended to be placed around a primary conductor, and a secondary winding that is wound onto a portion of the magnetic circuit in order to deliver a secondary current to processing circuits. In this current transformer the magnetic circuit includes at least one device for varying the magnetization of a portion of the magnetic circuit according to the temperature in order to limit or to decrease the magnetic flux in the magnetic circuit when the temperature of the magnetic circuit increases. The protection device and the electrical circuit breaker include such a transformer.

A safety switching device for controlling a load having at least one input for receiving an input signal and one output for outputting an output signal, and having an electrical circuit which provides the output signal as a function of the input signal. The electrical circuit is arranged on a printed circuit board and is coupled to at least one setting component for setting an operating parameter of the safety switching device. The surface of the printed circuit board defines a mounting plane, and the at least one setting component has an adjusting element in a housing and is arranged recessed on the printed circuit board so that the housing of the adjusting element intersects the mounting plane.

Disclosed herein is a leakage protector, which includes a housing. A base plate and a brush are arranged in the housing. A first conducting strip and a second conducting strip spaced apart are arranged on the base plate. The brush is provided with contact pins to contact the first conducting strip and the second conducting strip, respectively. The second conducting strip can generate different analog voltages, and the first conducting strip is configured to transmit different analog voltages to a microprocessor. A user can drive the brush to move through an actuating part, and set the power-on time of the leakage protector in one step.
