Overview of circuit breakers from SEZ Krompachy

The Slovak company Sez Krompachy has been manufacturing low and high voltage devices for over 69 years. The range of the brand is quite wide and includes RCDs, circuit breakers up to 125 A, wiring material, cam switches, switchboards, all kinds of disconnectors and switches. A distinctive feature of the company is the use of closed-cycle production - all component parts of products and materials are manufactured in Europe, checked in accordance with standards. The presence of ISO and other quality management system certificates confirm that the plant produces products of decent quality, which are exported around the world. In Russia, the brand is not as widespread as in Ukraine, where the products of the plant can be found in almost every city. In today's review, we will talk about circuit breakers SEZ.

Application area

Circuit breakers of the PR series are devices of the European quality standard, designed to turn on, conduct and turn off currents under normal conditions and to independently turn off in specific extreme situations, for example, an overload of the mains or a short circuit.

SEZ machines provide protection against overcurrents in the wiring of residential and administrative buildings, switchboards or other equipment. They do not require special care and may not be serviced by specialists.

Modular automatic machines can also be operated as main switches for disconnection or guaranteed isolation. They are often used to protect circuits of heating appliances, sockets, lighting fixtures, and industrial machine tools in production.

Design and functionality

The design of the machines is quite aesthetic and pleasant. Depending on the rated current of the fuse settings, the switches have multi-colored handles (for characteristics B, C, D), with characteristic M - black.

0.5-4A - brown;
6-8A - turquoise;
10-13A - red;
16A - gray;
20A - blue;
25A - yellow;
32A - purple;
40A - black;
50A - white;
63A - orange.

On the facade of the PR switches there is a status indicator that allows you to monitor whether the machine is on (red) or off (green). The indicator of the machine is directly connected to the mechanism of the switch and is not determined by the position of the handle, since it also works when the control handle is locked, meeting all safety conditions.

Above the handle of the device there is a special nameplate on which you can write the legend of the purpose of the device. The plant provides the service of manufacturing plates with inscriptions on an individual request.

Mounting Features

The circuit breaker is easily mounted on a DIN rail. Using the bottom latch with a spring, you can remove the desired machine from the line of devices connected by the lower bus, without disturbing the current circuits. And the upper movable latch makes it possible to replace the circuit breaker from the row connected by the upper bus.

The thoughtful design of the terminals provides effective protection against contact. All devices mounted on a DIN rail, if necessary, are connected by a single busbar. In addition, you can add and combine additional components.

The handle can be sealed on and off. On the contact groups - fasten the protective covers and seal with a special plug.

The main advantage of SEZ machines is European reliability, and they are, they say, indestructible. In addition, the plant gives a three-year warranty on each product. At the same time, the price is one of the lowest in the segment of 10 kA automatic machines of European manufacturers. The best confirmation of quality is the use of brand circuit breakers by leading Ukrainian manufacturers of voltage stabilizers in the manufacture of their products.
