Abstract

The invention relates to a modular electric protection unit. The height of the unit is increased comparing with a standard height of the unit, thereby forming an additional volume (20) between a mechanism (19) and a terminal. The additional volume (20) is designed a member with a complementary electrical function. The maximum height U of the additional volume (20) is (((X-Z) / 2) / 3 / 4)-V, wherein the Z is a height of a nose (8) of the unit, the V is a height of a housing (38) of the terminal (13), the X is the minimum distance standardized between two rails, these heights are measured parallel to the rear surface of the apparatuses and perpendicularly with the longitudinal direction of rails.

Description

technical field [0001] The invention relates to a modular electrical protection unit comprising at least one module, each module arranged in a substantially parallelepiped-shaped housing, said housing comprising means for fixing to a mounting rail, called a first rail a rear panel, a front panel comprising a raised portion and a manually operated device accommodating the unit, said housing comprising a line-side terminal at one end thereof and a load-side terminal at an opposite end thereof, and between these line-side and load-side terminals housing unit mechanism, the unit also includes a supplementary electrical function, such as a differential function, the unit can be arranged above or below the same unit fixed to the second track, the second track is generally in the same position as the first track extending in a plane and parallel to the first rail, the two rails being separated by a standard minimum distance. Background technique [0002] Differential circuit break...
