Problems solved by technology

Because the device may be placed close to the heating element of the electromagnet, there is a risk that the exact opening and closing times of the auxiliary contacts will not be repeatable but will depend on the state of use of the device
Also, magnets can attract metal particles that can prevent electrical contacts from closing properly, and magnets also add cost

Embodiment Construction

[0023] Low-voltage electrical switching equipment, especially contactors, relays, circuit breakers or contact circuit breakers, require the use of pole moving contacts to switch electrical loads such as motors. The electrode movable contact can be kept in contact with or separated from the electrode static contact. For example, in a double-break device, each pole of the device includes two stationary contacts that cooperate with two movable contacts fixed in the pole contact holder, which can be freely The ground moves between the rest position R and the working position T. In the "closed" condition of the contacts, the electrode contacts remain in the operating position T. In the "open" condition of the contacts, the electrode contacts remain in the rest position R.

[0024] The control electromagnet of the device is provided with: an exciting coil 20, which is of the DC power supply type; and a magnetic circuit, which includes a movable arm fixed on the electrode movable c...

Abstract

The device has a control electromagnet provided with a movable pallet between a resting position and a working position under action of a coil (20). A slide coupled with the pallet operates an auxiliary contact (10) to provide a hysteresis function such that open and closed states of the contact obtained at end of course brings the pallet into working and resting positions, respectively. An Independent claim is also included for an electrical interrupter with a control device.

Description

technical field [0001] The invention relates to a device for controlling an electromagnet in a low voltage electrical switching device, such as a contactor, relay, circuit breaker or contact circuit breaker, wherein the field coil comprises a supply circuit comprising auxiliary contacts. The invention also relates to a switching device comprising the control device. Background technique [0002] The switching device has an electrode static contact, and the electrode static contact cooperates with the electrode movable contact so as to switch the electric load on the output side. These switching devices also include a magnetic circuit including a movable armature connected with an electric movable contact controlled by the field coil when an electric field current is passed through the field coil. Operation generally proceeds according to the following principles. [0003] In the first phase, called the inrush phase, a sufficiently high inrush current is passed through the ...
