A modular device comprises a housing and a terminal arranged therein with a clamping screw, a pressure plate and clamping frame, a first recess on the connection side for transversely receiving a busbar passing through the housing and clamping frame, and the insulating gap between the outer edge of the clamping frame within the housing and the outer side of the adjoining closed housing side being smaller than the air insulating gap between the outer edge of the clamping frame in the region of the recess and the outer side of the adjoining housing side.

Modular device assembly with a terminal

A circuit breaker, and particularly, though not exclusively, an automatic cut-out or line-protective circuit breaker, which includes a housing, an electric arc chamber arranged within the housing, a fixed contact and a movable contact located in the arc chamber, a current supply line forming a U-shaped current loop with the contacts. The arc-extinguishing chamber incorporates arc-extinguishing plates for guiding the path of the arc into the electric arc chamber to the extinguishing chamber, and in which plates of a magnetically-conductive material extend in parallel with the plane of contact movement up to opening or breaking thereof, and extend from the contacts to the arc-extinguishing chamber, and a gas-emitting coating being provided on each of the plates and constituted of an electrically-insulating material which emits gas when heated.
