The Slinky was invented in 1945 by Richard James. It conveys the full fascination of physics – and simultaneously symbolizes pure flexibility. This symbolism is reflected in the core values of Gruner AG. In the area of latching relays for smart metering, the company is the undisputed technology leader and world market leader. Assuming one switching operation per day in load control and one every week in prepayment applications, there are more than 1000 Gruner relays switching every second – worldwide. About current sensoring Using a latching relay in energy management also requires a current Sensor. Today four major different current sensing technologies are available: current transformer, hall sensor based, Rogowski coil, shunt resistor. Gruner relays are available with an integrated shunt resistor. A strip of high precision shunt material is electron beam welded between two copper strips. The terminals of the relays could also be customized to integrate other current sensoring technologies. Lamp load Another application for latching relays is lamp load switching. Because of high inrush current the 707L and 704L relays were adjusted to meet this requirement. They switch lamp load up to 4800 W or 200 µF parallel compensation. A strong connection between the H-armature and contact spring allows the relay to break micro welded contacts caused by the high inrush currents. All Gruner relays meet the IEC 62053-21 and IEC 62054-11 requirements. In addition relay types 721, 722, 723, 725, 733, 736 and 741 meet Utilisation Category UC3 in accordance with the new IEC standard 62055-31. For new developments we recommend to use relay type 725. Polarized latching relay for 100 A Using the H-armature principle the polarised latching relays are noted for their high resistance to shocks and vibrations. They are always in a defined switching position and therefore there is no loss of information in case of power failure. The advantage of polarised latching relays is the pulse driven operation of some milliseconds, coil heating can be neglected. Optionally the relay can also be set by manual operation. The relays are designed and manufactured in accordance to international standards of IEC 61810 part 1 as well as they meet the UC3 requirements for Supply Control Switches as of IEC 62052 part 31.
