ER4X-400N3PB

Disconnect Switch Components

ER4X-400N3PB are an important type of disconnect switch components. Specifically, they are designed mainly for use in switching functions of control and protection of electric equipment and circuits. Developed by top-notch industrial experts, ER4X-400N3PB are the best choice for new industrial installation, one because of their reliable performance, another because of their ventilation/insulation structure.

Application Field

ER4X-400N3PB disconnect switch components are considerably utilized in a wide range of applications. The exact fields are general purposes, general industry, electric boards, electric devices, and plug-ins for industrial applications. The electrical isolation of power supply circuits in all these applications can be efficiently provided by use of ER4X-400N3PB disconnect switch components.

Working Principles

The ER4X-400N3PB disconnect switch components are two-pole disconnects, meaning that they are designed to protect both phases, set-up in an ‘on-off’ mode with either pole individually protected by an independent physical switch. The electrical input current is distributed to two single pole switches, meaning that the disconnect switch can be individually turned on or off safely. Additionally, it can also be used in AC-DC bi-directional and DC-DC applications. To ensure complete safety, the two poles are linked by a mechanical interlock, making sure that switching is conducted in a safe and reliable manner.

Moreover, the design of the ER4X-400N3PB includes insulation with ventilation, phasing, blocking chamber, and motorized switching system. The insulation is essential for the performance of this device, helping it protect fluids from wet and short circuits. The ventilation is necessary to keep the components cool, and to prevent ventilation cuts. The phasing connection is important to avoid phase mismatches and wire connection errors that could lead to faulty operation. The blocking chamber and the motorized switching system both ensure better safety during operation.

All in all, due to their reliable performance and simple structure, ER4X-400N3PB disconnect switch components are a preferred choice for many industrial applications.
