Blokset low-voltage switchgear


Product Overview

It is a full-type test product, a TTA product.

The installation method is flexible and can be designed for wall-mounted installation; operation, maintenance, and wiring can all be performed from the front of the panel. Alternatively, it can also be installed away from the wall, with wiring exiting from the back of the panel and allowing maintenance from both sides.

Modular and multifunctional systems, with a modular design that facilitates left-to-right expansion and assembly, significantly reduce downtime.

The separation type is clearly defined, safe and reliable, and the isolation form is 3b.

High installation density saves 20% of cabinet space, reducing both the number of switchgear panels and the overall footprint.

The drawer functional unit has four positions—operating, testing, disconnection, and withdrawal—and maintains an IP2X protection rating regardless of its position. It features a rational design that is easy to operate and maintain.

The entire switchgear features a modular design, making it easy to add, expand, and modify circuits.
