Problems solved by technology

In this case, the circuit breaker must be fixed to the support at a certain distance above or below the variable speed drive, which makes the assembly particularly bulky
Furthermore, since the depth of the variable speed drive is much greater than that of the circuit breaker, and both units are secured to the same support, for example at the bottom of the distribution cabinet, the unit used to operate the circuit breaker is difficult to access

Embodiment Construction

[0023] The invention relates to a control assembly comprising a variable speed drive 10 and an electrical switching device such as, for example, an electromechanical contactor or a protective circuit breaker.

[0024] In the following description, the electrical switching device described is a protective circuit breaker 20 . It should be understood that the invention is equally applicable to electrical switching apparatus of the electromechanical contactor type.

[0025] In the following description, the expressions "front" and "rear" are to be understood as the parts of the variable speed drive delimited by the middle vertical cross-section with respect to the depth of the variable speed drive.

[0026] The variable speed drive 10 is used to control an electrical load (not shown), as is well known, and includes a power terminal block to which power lines are connected. The power terminal module includes upstream power terminals (top) 104 and downstream power terminals (botto...

Abstract

The invention relates to a control assembly consisting of: a variable-speed drive (10) for controlling an electric charge, said variable speed drive including rear attachment means (101) for attaching same to a mounting (30) and a power terminal board receiving a power via power lines; and an electrical interrupter connected to the power lines in order to control or protect the variable-speed drive (10), wherein the electrical interrupter is electrically connected to the power terminal board of the variable-speed drive, and the control assembly includes attachment means for mechanically attaching the electrical interrupter to the variable-speed drive (10) only.

Description

technical field [0001] The invention relates to a control assembly comprising a variable speed drive and an electrical switching device, such as an electromechanical contactor or a protective circuit breaker. Background technique [0002] It is known to produce a control assembly for controlling an electrical load comprising a variable speed drive and an electrical switching device such as for example a protective circuit breaker. In this assembly, the variable speed drive notably includes a power terminal module receiving power current via a current line, and a circuit breaker is connected to the power line to protect the variable speed drive in case of overload or short circuit. [0003] Typically, the variable speed drive is fixed to the support by means of fixing means, and the circuit breaker is also fixed to the same support, eg by mounting to a DIN rail. In this case, the circuit breaker must be fixed to the support at a certain distance above or below the variable s...
