Coil accessories General Information Industrial Relays C2-C9 Protection against transients When the coil is disconnected from an electromagnet, peaks of inverse voltage appear at the terminals which can reach very high values. These pulses can be transmitted down the line associated with the coil and could possibly affect other components. In the case of a realy being operated by such devices as transistors, Triacs, etc; it may be necessary to protect against transients. Transients carried in the line High voltage surges can be carried in the supply line to the relay coil. These may appear in...

Industrial Relays General Information Contacts There are different contact types. The main distinction is between single contacts and twin contacts. While single contacts are more suitable for higher loads, twin contacts are significantly more reliable at small loads, i.e. < 24V, < 100mA. Contact Material There is no all-purpose contact! AgNi is used as standard material for a wide range of applications. AgNi contacts with hard gold plating (up to 5µm) are offered for applications in aggressive atmosphere. Relays with gold contacts are approved for relatively high currents (e.g. 6A, 250V), but...

Industrial Relays General Information Standards, conformities All ComatReleco relays feature the CE mark to indicate that CE standards apply e.g. 2kV surge resistance according to EN 61000-4-5. A significant and not generally available characteristic is that the coils and in particular the connections are able to withstand the voltage spikes that may occur in practice. In addition, the relays feature various technical approvals depending on the respective relay code, and they comply with further standards and guidelines. The main technical approvals include cURus, CCC, Lloyd‘s Register, cULus...
