Abstract: A ceiling fan with electrical illumination has a fan casing and a connection casing for connection of a fan motor and at least one light source to a power supply system. An electronic control device integrated in the ceiling fan automatically limits the electrical power drawn from the power supply system by the light source(s) to a predetermined power value.

Abstract: A portable electrical luminaire (1) having a supporting body (2) having an upper support end (2a) and having a lower support end (2b), having a lamp base (3) arranged on the upper support end (2a) for accommodating a luminous means (4), having a reflector (5) surrounding the lamp base (3) for indirect space illumination purposes, having a connection line (7) which is electrically connected to the lamp base (3) and having a connection plug (8) for connection to a power supply system (UAC), and having an electronic control device (11), which is designed to automatically limit the electrical power (P(t)) drawn from the power supply system (UAC) by the luminous means (4) to a predetermined value (Pmax).

Abstract: A portable electrical luminaire has a supporting body with an upper support end and a lower support end. A lamp base is disposed on the upper support end for accommodating a luminous device. A reflector surrounds the lamp base for indirect space illumination purposes. A connection line is electrically connected to the lamp base and has a connection plug for connection to a power supply system. An electronic control device is configured to automatically limit the electrical power drawn from the power supply system by the luminous device to a predetermined value.

Abstract: A bimetal controlled circuit breaker includes a current bus that is electrically connected in series with the bimetal element. The current bus extends parallel to the bimetal element in the deflection plane of the latter and is rigid relative to the bimetal element. The deflection of the bimetal element is supported by the action of electrodynamic forces. In order for the circuit breaker to be suitable for greater current intensities and the effect of the electrodynamic forces to be better utilized, the bimetal element is electrically connected in parallel with a shunt path.

Abstract: A circuit breaker which is remote controllable by an external remote control switch by way of an electronic control unit and an electromagnetic switch drive controlled by the electronic control unit. The switch drive switches the electric circuit by a switch lock, which is latched to it and which, during an overload, is unlatched and opened by way of the release of the bimetal of switch drive and, as a result, interrupts the electric circuit. During bimetal release, an auxiliary switch is actuated, which by way of the electronic control unit turns the remote control switch off and re-latches switch drive with the opened switch lock.
