Abstract

Die Erfindung betrifft einen dreipoligen Leistungsschalter (1) sowie ein Verfahren zu seiner Herstellung mit einem Schaltschloss (14), wobei jedem Pol (5-7) ein eigener Kurzschlussschnellauslöser (19-22) zugeordnet ist, der beim Auftreten von Kurzschlussströmen in dem entsprechenden Pol (5-7) ein Verschwenken einer Auslösewelle (50) bewirkt, welche auf das Schaltschloss (14) des Leistungsschalters (1) wirkt. Um zu erreichen, dass der Leistungsschalter durch Änderung eines vorhandenen vierpoligen Schutzschalters mit Schaltschloss (14) herstellbar ist, bei dem trotz eines zusätzlichen Kurzschlussschnellauslösers (22) für den Pol (7), der ursprünglich mit einem Neutralleiter verbindbar war, das Schaltschloss (14) konstruktiv nicht verändert werden muss, schlägt die Erfindung vor, dass der zusätzlich benötigte Kurzschlussschnellauslöser (22) auf eine zweite Teilwelle (28) der Auslösewelle (50) wirkt, die beim Auftreten eines Kurzschlussstromes in dem diesem Kurzschlussschnellauslöser (22) zugeordneten Pol gegen den Druck einer zweiten Rückstellfeder (29) von ihrer Ruhestellung in eine Betätigungsstellung verschwenkt wird. Dabei nimmt die zweite Teilwelle (28) über Koppelmittel (30) die erste Teilwelle (23) (d.h. die ursprüngliche Auslösewelle) mit, die ebenfalls gegen die Kraft einer ersten Rückstellfeder (24) von ihrer Ruhestellung in ihre Betätigungsstellung verschwenkt wird und beim Erreichen ihrer Betätigungsstellung das Schaltschloss (14) auslöst. Sofern ein Kurzschlussstrom in einem der beiden anderen Pole (5, 6) des Leistungsschalters (1) auftritt, wird zwar die gemeinsame erste Teilwelle (23) gegen den Druck der ersten Rückstellfeder (24) verschwenkt und löst das Schaltschloss (14) aus, doch sind die Koppelmittel (30) der beiden Teilwellen (23, 28) derart ausgebildet, dass die erste Teilwelle (23) in diesem Fall die zweite Teilwelle (28) nicht mitnimmt, so dass diese in ihrer Ruhestellung verbleibt.

The invention relates to a three-pole circuit breaker (1) and a method for its production with a switching mechanism (14), wherein each pole (5-7) is associated with its own short-circuit rapid release (19-22), which in the occurrence of short-circuit currents in the corresponding pole (5-7) causes a pivoting of a trip shaft (50) which acts on the switching mechanism (14) of the circuit breaker (1). In order to achieve that the circuit breaker by changing an existing four-pole circuit breaker with switch lock (14) can be produced, in spite of an additional short circuit quick release (22) for the pole (7), which was originally connectable to a neutral conductor, the switching mechanism (14) must not be changed structurally, the invention proposes that the additionally required short circuit quick release (22) acts on a second part of shaft (28) of the trigger shaft (50), the short-circuit current in the short-circuit rapid release (22) associated pole against the pressure at the occurrence of a short circuit current a second return spring (29) is pivoted from its rest position into an actuating position. In this case, the second part shaft (28) via coupling means (30) with the first part shaft (23) (ie the original release shaft), which is also pivoted against the force of a first return spring (24) from its rest position to its operating position and upon reaching her Actuating position the switch lock (14) triggers. If a short-circuit current in one of the other two poles (5, 6) of the circuit breaker (1) occurs, although the common first part shaft (23) against the pressure of the first return spring (24) pivots and triggers the switching mechanism (14), but the coupling means (30) of the two partial shafts (23, 28) are designed such that the first partial shaft (23) in this case does not entrain the second partial shaft (28) so that it remains in its rest position.
