If circuit-breakers (2) with locking slides (4) that can be displaced vertically are used, the control member (10) is situated underneath the circuit-breaker (2).
The invention relates to a power circuit-breaker, especially a differential current circuit-breaker, comprising a summation current transformer (6) which monitors a supply network (Ln).
A high voltage hybrid circuit-breaker has an arc circuit with a gas circuit-breaker (30) connected in series with a vacuum bulb (54).
A generator circuit-breaker disconnecting switch according to the invention has a compact structure.
It is sought to enhance the reliability of the optical detector in the supervision device of electrical arcs in a high power circuit-breaker insulated with SF6.
The invention concerns a circuit breaker support (27) comprising means for co-operating with at least a circuit breaker insulating accessory and a circuit breaker assembly comprising at least a circuit breaker and such a support (27).
A second circuit breaker portion includes a second circuit breaker enclosure.
The first circuit breaker portion includes a first circuit breaker enclosure.
The circuit breaker based on the invention is combined with a circuit breaker housing (1), a circuit breaker (2) and a built-in light indicating electricity meter (3).
A circuit interrupter handle mechanism is disposed on the face of a molded case circuit breaker.
An improved viewing window construction for an electrical disconnect switch (10).
This invention involves miniature circuit breaker (automatic fuse) with functions of electromagnetic and thermal circuit breaker.
The ultrathin miniature circuit breaker is only 9 mm thick, which is half the thickness of a conventional small circuit breaker, so as to reduce the space occupied by a distribution box, reduce the cost, and achieve desirable performance.
The protection switch (1) comprises at least one single-pole protection switch module (2).
cycle switch
weld controller (in which the timer only opens the welding contactor)
The protection switch (1) comprises at least one single-pole protection switch module (2).
The invention relates to a power output stage (T) which is charged with a high charging current (Ig1) in order to effect an electromagnetic interference-compatible control.
The disconnector poles of the respective disconnectors lie one above the other above the switch poles (12, 13, 14).
Lastly, the disposition of the circuit breaker rotary handle provides an indication of the conduction status of the molded case circuit breaker.
The circuit breaker may further include an arc fault circuit interrupter (AFCI) and a ground fault circuit interrupter (GFCI).
The sliding connection facilitates assembly of the circuit breaker (10) and also permits a reduction of size for a circuit breaker of a given rating.
The breaker failure detection unit is arranged for assessing, whether the circuit breaker has failed, and sending, if the circuit breaker has failed, a trip signal (109) to an adjacent circuit breaker.
The purpose of the present invention is to provide: a circuit breaker capable of efficiently performing a shutoff operation; and a circuit breaker operating method.
This can have the advantage of preventing arcing from the breaker contacts to the breaker box.
