INNOVATION WITH QUALITY – GRUNER RELAYS
Latching relays from Gruner are individually developed solutions that set global standards and that are frequently specified by the industry. Today, Gruner is one of the last independent manufacturers of relays in Germany, and it is the undisputed technology leader and world market leader for latching relays in the energy management sector. ’Innovation, not imitation’ is our motto for delivering relays to the market and to applications.
INNOVATION AND QUALITY
THE GLOBAL LEADER FOR METERING
Even smaller but just as powerful. The Gruner 726 relay is a consistent further development of the 700 series. With its superlative properties and the ‘shared-design’ principle, the 700 series of polarised latching relays covers a diverse range of energy management functions. These include load management, tariff switching, disconnect-reconnect applications and prepayment.
- Great switching power with minimal power consumption
- Great switching reliability and optimised service life
- Great reliability with a minimum of mechanical components
- Exceptionally wide range of switching powers

GRUNER 48 VOLT RELAYS
48V – ACHIEVED ECONOMICALLY
The Gruner 850 relay is the first relay for 48V applications in the automotive sector.
With the 852 relay, the 2nd generation of 48V relays is now available. 48V technology is used primarily in mild-hybrid vehicles for the management of lithium ion batteries. Due to their higher voltage, many functions in vehicles can be electrified without the additional weight of an extra battery. This enables the size of the engine to be reduced, which cuts down on CO2emissions.
The 852 relay is characterised by a higher level of power capacity. Here, a small controllable electronic unit is also integrated, together with an option for measuring and reading out the temperature on the contacts. 48V technology (MHEV) offers a cost benefit across the board: compared to plug-in-hybrids (PHEV) or fully electric vehicles (BEV), the system costs are relatively low.

FOR CHARGING AND STORAGE
Plug-in hybrids and electric vehicles frequently get charged at wall charging stations, known as ’wall boxes’. Gruner developed its 4-pin 800 relay specifically for the charging & storage sector. It acts as an isolating relay in wall boxes up to 22 kW. It serves as an isolating relay in wallboxes up to 22kw, and can also withstand overcurrents up to 3,000A.
