Definitions
- the invention relates to an electromagnetic current release for an electrical circuit breaker with a magnet coil, a movable armature and a stationary magnet core, which is held by a current connection terminal of the magnet coil.
- Generic electromagnetic current releases according to FIG. 2 are used to detect overcurrents, in particular short-circuit currents, in conventional electrical circuit breakers in order to protect single-pole and multi-pole electrical consumers against impermissible operating states.
- These circuit breakers can be circuit breakers, motor circuit breakers and circuit breakers. Depending on the applicable regulation, you must switch off overcurrents within certain response limits.
- the current releases are coupled to the contacts of the circuit breakers to be opened in such a way that they open and, if necessary, keep them open in response to an overcurrent or short-circuit current.
- such current releases 1 are composed of a magnetic coil 2, a coil part 3 with a guide tube 4, a movable armature 5, a stationary magnetic core 6, a spring 7 and a current connecting terminal 8.
- the coil frame 3 with the guide tube 4 is made of insulating material.
- the magnetic coil 2 is wound or plugged around the coil frame 3.
- the armature 5, which is movably mounted in the guide tube 4 moves against the spring force of the spring 7 in response to an overcurrent or short-circuit current. In this way, opening of the contacts located in the current path is achieved via corresponding mechanical coupling elements.
- a magnetic core 6 is pressed in the guide tube 4 of the coil frame 3 or in the connecting 2 terminal 8, as shown in FIG 2, a magnetic core 6 is pressed.
- the magnetic core 6 is an additional part, which is preferably mounted inside the guide tube 4, that is to say at least partially in the interior of the magnet coil 2.
- the invention has for its object to partially minimize an electromagnetic current release of the type mentioned above and thus economically.
- the object is achieved in that the magnetic core and the power connector are made in one piece.
- a particularly inexpensive embodiment is provided when the magnetic core and the power connection terminal are manufactured as a one-piece stamped and bent part.
- the electromagnetic current release 1 is composed of a magnetic coil 2, a coil frame 3 with a guide tube 4 made of insulating material, a movable armature 5, a stationary magnetic core 6, a spring 7 and a current connection terminal 8 as essential elements.
- the magnet coil 2 is wound around the coil frame or attached to it and is part of the current path of a consumer to be protected.
- the armature 5 is movably mounted in the guide tube 4 and reacts to a short-circuit current. The movement of the armature 5 causes corresponding mechanical coupling links to open contact points located in the current path. The armature 5 moves against the force of one also in the guide tube 3 4 mounted spring 7.
- a stationary magnetic core 6 is arranged in the guide tube 4 of the coil frame 3, which is made together with a power terminal 8 for the magnet coil 2 as a one-piece part.
- This part is advantageously designed as a stamped and bent part.
