“””Panel mounting type 4 pole”” or “”3 pole”” refers to the configuration of electrical components, typically switches or circuit breakers, that are designed to be mounted onto a panel or enclosure. These terms are commonly used in the context of industrial control panels, distribution boards, switchboards, and other electrical systems.

Here’s a breakdown of the terms:

Pole: In electrical terminology, a “”pole”” refers to a circuit or a set of contacts that can make or break an electrical connection. Each pole typically consists of a pair of contacts (one movable and one stationary). The number of poles determines how many separate circuits the device can control simultaneously.

Panel Mounting: “”Panel mounting”” refers to the method of installing an electrical component onto a panel or an enclosure. This is commonly done using screws or other fasteners to secure the component in place.

3 Pole: A “”3 pole”” configuration implies that the device has three separate circuits or sets of contacts. This means that the device can control three separate electrical connections independently. It might be used to switch or control three different loads or circuits.

4 Pole: Similarly, a “”4 pole”” configuration means that the device has four separate circuits or sets of contacts. This provides the capability to control four independent electrical connections.

The number of poles is important in various applications. For instance, in a circuit breaker, each pole could correspond to a different phase of an electrical system, allowing for the protection and control of multiple phases. In motor control applications, each pole might control a different aspect of a motor’s operation.

When selecting a panel-mounted switch, circuit breaker, or any other control device, it’s important to choose the right number of poles based on the specific requirements of the electrical system or equipment being controlled.”
