A mechanical switching device which, in the open position, complies with the requirements specified for isolation.

A mechanical switching device which, in the open position, complies with the requirements specified for the isolating function.

This can be a load-break switch, whose phases are combined with cutouts, or a load-isolating breaker.

The invention relates to a low voltage switchgear with a bimetallic actuator, especially to a motor safety switch or a power switch.

The invention relates to switchgear (100) which has at least one circuit breaker or switch (107), an earthing switch (113) and a disconnector (105).

The switchgear panel (10) has a plurality of electrical components, particularly circuit breakers, isolator/earthing switches or the like.

WEB - disconnect switch or isolator switch is used to ensure that an electrical circuit is completely de-energized for service or maintenance.

In electrical engineering, a disconnector, disconnect switch or isolator switch is used to ensure that an electrical circuit is completely de-energised for service or maintenance.

A disconnector can be associated to a switch, but this one has a limit in terms of maximum current opening.

A driving device for a disconnecting or earthing switch (17) has driving parts (25) which may be actuated by means of a coupling set (23) by a crank handle (20).

The circuits incorporate an ignition switch (8), an override switch (80), a vehicle reverse switch (40), and an operator presence switch (12).

The output side of the fourth switch (204) is connected to the output side of the second switch (203) and supplies the gate voltage to the memory cell (207) at the time of the first mode.

A gas-insulated switching unit has a gas-filled housing (2) containing a multi-pole vacuum switch (3) and a three-position load-break switch (5) arranged below it.

The genetic recipe enabled the cell to make the equivalent of a light switch.

A second switch is in series with the first switch.

An interrupter unit of a high-voltage power circuit breaker has two arcing contact pieces (1, 2), between which an arc (4) is struck in the event of a break.

A vacuum interrupter assembly comprises at least one vacuum interrupter (10).

The power isolating switch can lock the electrode against removal when the power isolating switch is in the 'on' position.

Said isolating switch device (32) comprises a separating switch (34), which can disconnect a main line (36A, 36B) from the electric power source (12) to at least one consumer.

When the power isolating switch is moved to the 'off' position, the electrode can be removed.

The aim of the invention is to devise a disconnector (1) for switchgear which disconnector allows for a compact and space-saving design.

Either set of switches includes a disconnector I, a breaker I and a disconnector II connected in series.

A disconnector assembly (10) is provided for an arrester (13).

A disconnector assembly (10) is provided for an arrester (13).

The upper isolator (2), the vacuum arc extinguishing chamber (12) and the lower isolator (18) are connected each other fixedly.

A signal is sent through the first galvanic isolator and received through the second galvanic isolator by the detection unit.

The output of the isolator (20) is connected to a complementary circuit (120) distant from the isolator via a fibre-optic cable (110).

The feed circuit of the audible alarm (1) is provided with a microswitch (4) which is normally open and which is activated by the control device (5) of the earthing isolator of the cell.

In the parameterization of electronic tripping devices of circuit breakers, an adjustment of the tripping device by unauthorized persons must be prevented.

The conductor may form a mobile contact for a circuit-breaker.

A generator circuit-breaker disconnecting switch according to the invention has a compact structure.
