Focus on latching relays: innovation, not imitation.

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.
