A multi-pole circuit breaker and method include at least two breaker modules including circuit breakers therein.

The disconnector poles of the respective disconnectors lie one above the other above the switch poles (12, 13, 14).

A multi-pole circuit breaker and method include at least two breaker modules including circuit breakers therein.

The best point to reclose the circuit breaker corresponds to the region where the voltage pulse amplitude between the circuit breaker poles is the lowest.

This invention pertains to an automatic single- or multi-pole circuit breaker (1) for use in lowvoltage applications.

The circuit breakers (20) include a digital code circuit which is manually set to indicate the type of circuit breaker, for example, a one, two or three pole circuit breaker.

Said switchgear is characterised in that the circuit-breaker poles (111, 112, 113) run horizontally above one another on a vertical plane.

The said circuit breaker unit of the electrical ring main unit comprises a plurality of separate pole assemblies.

The circuit breaker can be multiple poled installed with 1,2 or 3 poles which will simultaneously protect and switch one to three lines.

After the circuit breaker opens a transmission line, the interaction between the transverse admittance of the line and the inductance of the compensation shunt reactor causes the voltage between the poles of the circuit-breaker to oscillate (pulse).

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.

A circuit breaker includes a coil arrangement for actuating an armature to open the breaker.

Application: self-expansion SF 6 breaker.
