Model and meaning

Product Overview

This three-pole isolating switch series features a robust construction with a comprehensive assembly of components. Its foundational structure includes a sturdy chassis, around which a central shaft is mounted. The shaft serves as the pivotal element, supporting three pairs of precisely welded levers that act as key transmission components.​

The levers are intricately linked to ceramic pillar insulators and switch blades via pull rods. These pull rods enable the seamless transfer of motion, ensuring the smooth operation of the switch. The switch blades, which are crucial for establishing and breaking electrical connections, are attached to the levers, while the terminal blocks provide the necessary interfaces for electrical connections.​

Notably, the rotating shaft extends beyond the chassis boundary. This design offers flexibility, as any segment of the protruding shaft can be effortlessly coupled with an operating mechanism, facilitating easy and efficient control of the switch.​Among the variants, the Type C isolating switches are designed as through-wall models. This type is further categorized into three sub-types. C1 configuration allows rotation on the through-wall side, providing convenient operation access. C2 type is engineered for disconnection on the through-wall side, ensuring secure isolation of electrical circuits. C3 model features both sides located on the through-wall side, offering enhanced versatility and adaptability for various installation scenarios.
