LV500 – Charging connectors for industrial trucks

Charging connectors for 500 A comply with UL 1977 for a higher current-carrying capacity

LV500 Series
Schaltbau LV500 Series charging connectors assure safe operation and high reliability in the long term.

Delivering maximum performance and working in harsh environmental conditions requires reliable, durable and safe products. It is exactly these requirements that are met by the new Schaltbau charging connector. The low-maintenance and high-performance connector fulfils the expectations of the contemporary user: Modern fast chargers recharge vehicle batteries in short time or traditionally over night.


  • Higher current-carrying capacity: The new LV charging connectors comply with UL 1977 for a higher current-carrying capacity.
  • High-quality, screw-machine power contacts: Due to an improved design, the contacts feature a higher current-carrying capacity, minimum contact heating and a continuous low contact resistance. With constant contact force over its working life, the connector is less susceptible to wear and tear while mating and unmating.
  • Modular design: Standardized individual components can be used across the entire connector series. They allow for a customized and cost-effective realisation of your applications, and avoid unnecessary stocking of items.
  • Integrated lock function: The mated shells of the LV Series connectors provide positive locking resistance to shock, vibration and other decoupling forces that may occur under normal conditions of use.
  • High resistance to acids and extremes of temperature: The material used for the connector shells including strain relief is highly resistant to sulphuric acid of high concentration. The proven housing material makes for the connector’s ruggedness and suitability for use with temperatures ranging from -30° C to +130° C.
  • Auxiliary contacts, air tube adapter / additional pilot contact adapter:
    Auxiliarycontacts: Can be used for the function of the battery management system, which constantly monitor the condition of the battery, thereby guaranteeing maximum battery life.
    Schaltbau LV500 series charging connectors can be equipped with an additionall air tube or pilot contact adapter.
    Air tube adapter: For use with batteries with electrolyte circulation system or
    Pilot contact adapter: To be fitted with 2 optional pilot contacts which provide a data link between the battery management system and the charger.


The connector is typically used for industrial trucks and lifting devices, vehicle batteries, battery chargers and backup systems of UPS units.
