Problems solved by technology

[0013] However, in a three-phase distribution system (L1,L2,L3,N) with a neutral wire, to apply this solution in connection with three- and four-pole circuit breakers (3P,3P+N,4P) would be particularly difficult due to the resulting large size and high cost of

Embodiment Construction

[0027] Referring to the various figures, a control module according to the invention, generally designated by the reference numeral 1 , has a housing body 2 with a channel 3 into which an electrical cable 4 is inserted.

[0028] Inside the containment body 2 , a microswitch 5 is provided with a control lever 6 actuated by a movable armature 7 .

[0029] A stationary core or yoke 8 is arranged at least partially around the cable 4 , which attracts the movable armature 7 against the action of a return spring 9 .

[0030] The control module 1 according to the invention incorporates a reset device, which is not shown in the figures.

[0031] The cable wire 4 is inserted in the channel 3 like a kind of TA, while the corresponding magnetic field creates an attractive force between the movable armature 7 and the core 8 .

[0032] When the attractive force exceeds the magnitude of the spring and thus the actuating force of the microswitch 5, the microswitch breaks the contacts, which...

Abstract

The invention discloses a control module for an automatic reset device, the module includes: a housing body, the body is passed through by a conductor, and the conductor is connected to a circuit; and a micro switch, the micro switch is connected to the reset device; the module is characterized in that it comprises a fixed core and a movable member which is subjected to an electromagnetic field generated by an electric current flowing through said conductor, said movable member being capable of switching from said microswitch The active position of the micro switch moves to the inactive position of the micro switch; the movable member can move against the action of the spring; the force generated by the electromagnetic field causes the movement of the movable member.

Description

technical field [0001] The invention relates to a compact control module for automatic reset devices. Background technique [0002] As is known, after checking the correct operation of the system, an automatic reset device allows to automatically reset a circuit breaker operated by a residual current after opening of the circuit breaker. [0003] Circuit breakers operated by residual current are commonly installed in domestic and industrial systems to prevent fault currents from causing danger to users and loads connected to electrical circuits. [0004] Essentially, a circuit breaker operated by a residual current, when detecting the presence of a fault current, opens the line so that the supply of electricity to one or more loads arranged downstream is interrupted. [0005] After opening of the residual current operated circuit breaker, the residual current operated circuit breaker must be reset once the correct operating state for the system has been restored. [0006] ...
