Modern charging connectors with a new optimised main contact system: The solid power contacts can carry high currents with minimal self-heating, have extremely low contact resistance and noticeably reduced contact forces for a significantly longer service life.

Schaltbau devices and charging connectors meet the requirements of EN 1175 and DIN VDE 0623-589 for high current carrying capacity. They enable active energy and battery management that optimises the current flow and increase lifespan of the batteries.

Thanks to their modularity, Schaltbau charging connectors can be individually configured. Additional pilot contacts are available for battery management.
In addition to pilot contacts, adapters are also available to allow air to pass through during the charging process or to fill the battery with demineralised water.


High-quality, solid power contacts for a permanently high current carrying capacity

Schaltbau’s new optimised main contacts ensure a permanently high current-carrying capacity and minimal contact heating. These properties are achieved through very low contact resistances in the mated contact system over the entire service life. Thanks to reduced contact forces in the main contact system, there is less wear during mating and unmating. This extends the service life and also noticeably improves the ergonomics when mating and unmating.

Mechanical safety in rough everyday use

Schaltbau charging connectors have durable, robust housing components and reliably withstand rough everyday use. They also have the following important mechanical properties:

  • Integrated locking against shock and vibration: An easy-to-release locking device is integrated into the charging connector, which ensures functional safety in case of shocks and vibrations.
  • Integrated strain relief: Keeps the mechanical load of the connecting cables away from the electrically conductive contacts. In addition, the plug-in connection is secured against tensile, pressure and torsional stresses.
  • Integrated contact locking: The main contacts are safely aligned and fixed by a locking mechanism in the housing.
Arc prevention when plugging and unplugging the connector

Avoiding an electric arc when plugging in or disconnecting the connector increases safety, protects the main contacts and increases the service life. This goal is achieved by:

  • Last-mate/first-break signal contacts (LMFB): The signal contacts are designed in order to start the charging process after the main contacts are already plugged in and to end it before the main contacts are disconnected. The signal contacts in the control circuit enable timely disconnection and ensure load-free plugging and unplugging.
  • High Voltage Interlock Loop (HVIL): This so-called “power kill” contact, made with two signal contacts, enables timely disconnection in the control circuit and ensures load-free plugging and unplugging.
Modularity, interconnectivity, material properties

The connectors are modular in design and have excellent material properties.

  • Modularity: The low number of individual components and the usability in several series enable an individual and cost-effective realisation of your applications. Unnecessary stock positions are avoided.
  • Interconnectivity: The LV series is intermateable with commercially available charging connectors according to EN 1175 and DIN VDE 0623-589 with a comparable design.
  • High acid resistance: Resistance of the plastics to sulphuric acid according to EN 1175
  • Flammability: All plastics meet the glow wire resistance according to IEC 695-2-1 and the fire protection requirements according to UL 94-V0 and to EN 45545
  • Temperature resistance: The materials used stand for dimensional stability and functionality at
    temperatures from –30 °C up to +130 °C.
