Application area
Circuit breakers of the PR series are devices of the European quality standard designed to turn on, conduct and turn off currents in normal conditions and self-shutdown in specific extreme situations, for example, an overload of the mains or a short circuit.
SEZ circuit breakers provide overcurrent protection in residential and office wiring, switchboards or other equipment. They do not require special care and may be serviced by non-specialists.
Modular circuit breakers can also be operated as main switches for isolation or guaranteed isolation. They are often used to protect circuits of heating devices, sockets, lighting devices, in production - industrial machines.
Design and functionality
The design of the slot 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.
There is a status indicator on the front of the PR switches to monitor whether the circuit breaker is on (red) or off (green). The indicator of the machine is directly related to the switch mechanism and is not due to the position of the handle, since it is also triggered when the control handle is locked, meeting all safety conditions.
Above the handle of the device there is a special label on which you can write a legend for the purpose of the device. The plant provides a service for the production of plates with inscriptions on an individual request.
Installation features
The circuit breaker can be easily mounted on a DIN rail. With the help of the latch with a spring located at the bottom, you can remove the required 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 switch from the row connected by the upper bus.
The clever design of the terminal blocks provides effective protection against contact. All devices mounted on a DIN rail are, if necessary, 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, as they say, indestructible. In addition, the factory gives a three-year warranty for 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 the quality is the use of brand circuit breakers by leading Ukrainian manufacturers of voltage stabilizers in the manufacture of their products. This concludes our review of Sez Krompachy circuit breakers. For all questions, please contact in the comments under the post!
