Embodiment Construction

[0039]figure 1 An embodiment of the NH fuse load circuit switch 1 according to the present invention is shown in accordance with the present invention. The NH fuse load circuit switch or load circuit switch 1 is provided for a plurality of NH fuses. The load circuit switch 1 has a housing 2. The housing 2 is preferably composed of two portions and includes lower portions 2a and contact brackets 2b. In a preferred embodiment, the contact bracket 2b comprises a thermally conductive plastic. The housing 2 of the load circuit switch 1 is used to accommodate a plurality of NH fuses. To this end, it is preferred to setimage 3 The illustrated contact bracket 2b is shown. In the illustrated embodiment, the housing 2 of the load circuit switch 1 comprises three NH fuses NH1, NH2, NH3 for three different current phase L1, L2, L3. The NH fuse load circuit switch 1 can be assembled to the carrier rail, in particular on the bus bar. In the assembly state, the housing 2 of the load circuit switch...

Abstract

An NH fuse load break switch (1) has a housing (2) for accommodating a plurality of NH fuses, the NH fuses are vertically arranged in an assembled state, wherein the ) The waste heat generated by the NH fuse in the housing (2) is dissipated from the housing (2) upwards to the environment through the NH fuse arranged above it through the convection in the housing (2).

Description

Technical field[0001]The present invention relates to a NH fuse load circuit switch for a NH fuse having a high power density.Background technique[0002]The load circuit switch is used to disconnect the load or the appliance or device to the current or voltage distribution system. The current distribution system can include one or more power rails, especially bus bars. The electrical or load is used to connect to the current distribution system via the load circuit switch. The load circuit switch can include a plugable fuse, in particular NH fuse. In order to disconnect the current phase and the load, the user or operator can manually manipulate the joystick to disconnect the switch contacts within the negative carriage switch.[0003]A large amount of heat or exothermic is produced by the NH fuse in the housing of the NH fuse load circuit switch. Therefore, conventional load circuit switches have a relatively large housing, and correspondingly, in their assembly, there is a need for a...
