Embodiment Construction

[0015] The illustrated control and protection device comprises a circuit closer with a case 10 and a thermal protection relay with a case 20 fitted to the circuit closer. The circuit closer box 10 has an input power terminal 11 and an output power terminal 12, and a control-manipulation terminal block 13 on the front side, in other words, on the side accessible to the user. The term "control" mentioned in the following description is distinguished from the manipulation (or signal transmission) and control (or switching) functions of changing the state of the circuit closer by supplying power to the circuit closer coil. The control terminal block 13 is provided with an input-side control terminal 15 and an output-side control terminal 16, which can be respectively connected to a high voltage and a low voltage, and the control terminal block 13 protrudes forward beyond the front surface 14 of the box body 10, where The box body has a plurality of openings, and the tools can acce...

Abstract

The invention concerns a protection relay, in particular of the thermal type, recessed relative to its front face (24), a recess acting as through passage for interconnection of the conductors (C) between the terminals of the relay control (23) and of the contact switch (16). The recess (27) is concealed in normal operation by a shutter consisting of a flap (26) or a fixed part (26') of the housing (20). The interconnection conductors can consist of individual cables (C) or can be integrated to a precabling addition (40) housed in the recess.

Description

technical field [0001] The present invention relates to a protective relay, especially a thermal relay, which can be connected to a circuit closer and includes a box body provided with power connection terminals on the input and output sides and a control terminal, and the thermal relay is provided with a In front of manually operable equipment that is activated or adjusted. It is known that the power terminals on the input side and the control terminals of this type of protective relay must be connected to corresponding power and control terminals of adjacent circuit closers. [0002] The invention also relates to a protected control device comprising such a protective relay. Background technique [0003] Documents EP-256 900 and EP-828 270 disclose thermal protection relays in which the box is provided with a shutter on a selection, control or regulation device which must be inaccessible during normal operation, which can be folded by pivoting or slidin...
