In the modern world of Industry 4.0, it is essential to have a complete and reliable system of modular equipment capable of providing a solution to any problem relating to the protection, control and automation of industrial processes. Only a wide and varied range of products can respond to this type of need, consisting of automatic switches, pure differential switches, differential magnetothermal switches, surge arresters, modular contactors and numerous other complementary products, including all the accessories for their optimal management. The applications of these devices are truly infinite and, given the delicacy of the systems in which they are installed, it is always a good idea to check that these products are approved by recognized and qualified third-party bodies. The products of range ETIMAT, in addition to being designed and manufactured entirely within the European Union by the company ETI Elektroelement d.o.o. and marketed by ITALWEBER, have various product approvals, including the VDE (Germany), KEMA (Holland), OVE (Austria) brands and others.
The range is composed of numerous types of products, from the classic magnetothermal switches with curves B, C, D, K, Z and with breaking capacity of 6kA and 10kA, to pure differential switches, in classes AC, A, B, to differential magnetothermal switches in a single block. Among the various products offered we highlight in particular:
- 1P+N differential magnetothermal switches in 1 single DIN module (KZS-1M series). These products are electronic and are functionally dependent on the mains voltage. They are therefore ideal for protecting systems where additional high-sensitivity protections are required and must always be used downstream of classic differential switches. The differential protection is type A, and the differential sensitivities range from 10mA to 100mA.
- 2P differential magnetothermal switches with type B differential protection (KZS-4M-B series). This product is highly innovative and, in a single product, guarantees complete protection, both magnetothermal and differential, for all those applications where type B differential protection is required or is in any case highly recommended (charging stations for electric cars, electromedical applications, AC side of photovoltaic systems, etc.).
- 2P differential magnetothermal switches with integrated protection against electric arcs (AFDD series). In some cases, traditional differential magnetothermal switches are not able to offer adequate protection against faults caused by electric arcs (in particular in the case of a series arc fault). However, this type of fault is frequent in industrial electrical systems, and very often results in a fire. The AFDD series switches are designed specifically to detect and switch off arcs caused by faults in electrical circuits, and therefore perform a fundamental fire-prevention action, to protect people and property. Their use is particularly suitable in all places with a high risk of fire (wooden buildings, carpentry shops, fuel depots) or in places such as museums and libraries. The product is complete and innovative because it combines magnetothermal protection, differential protection and protection against electric arcs. The intervention caused by an electric arc is signalled by a special LED.
