It is impossible to keep electrical system entirely fault free. However, it is possible to minimise the impact of errors as much as possible, errors which in worst cases might result in complete system shutdown or failure. To prevent such damage, it is essential to use state-of-the-art measuring and monitoring relays, which constantly keep an eye on certain electrical and physical values. In ideal cases, in the instant an error occurs, these measuring and monitoring relays connect or disconnect, or send a defined signal to the control unit to prevent major damage to the system. Schrack Technik's range of products in this segment perfectly suits the parameters to be monitored. Our solutions of voltage monitoring relays (Series 5, Series 6), undervoltage monitoring relays (Series 5), current monitoring relays (Series 5, Series 6), phase monitoring relays (Series 5, Series 6), thermistor monitoring relays (Series 5, Series 6), and level monitoring relays (Series 5, Series 6) represent today's cutting-edge technology and offer maximum system protection.
