Abstract

Bekannte Niederspannungsschaltgeräte besitzen eine Lichtbogenkammer, die beidseitig von lichtbogenfe­ sten Vorkammerplatten, insbesondere aus Keramik, begrenzt ist. Known low-voltage switching devices have one Arc chamber, which on both sides of arct most prechamber plates, in particular made of ceramic, is limited.

In einem neuartigen Niederspannungsschaltgerät sind Vorkammerplatten (10) aus gelochten ferromagneti­ schen Metallplatten als Kern vorgesehen, welche mit einem gasabgebenden Isoliermaterial umspritzt sind. In a new low-voltage switchgear Pre-chamber plates (10) made of perforated ferromagneti metal plates provided as the core, which with are encapsulated in a gas-emitting insulating material.

Die neuartigen Vorkammerplatten finden insbesondere Verwendung bei Leitungsschutzschaltern. The new prechamber plates are particularly popular Use with miniature circuit breakers.
