VACK4 rod-type load break switch is general load break switch for indoor switchgear with standard DIN of VDE 0670 Part 301, VDE 0670 Part 303 and IEC Publication 60265-1. Suit for safe and reliable switching of all loads occurring in practice and particularly for switching transformers under load and no-load conditions, capacitor banks, cables, overhead lines, tee-off and ring lines under load and no-load. In the OFF position, LBS has a visible insulating gap, thus fulfilling the requirements for disconnectors in accordance with VDE regulation 0670, Part 2. Due to an optimum contact design and an operating mechanism,which permits high switching speeds, high making currents are safety mastered. The VACK4 LBS is able to close onto an existing short-circuit within the limits of its rated capacity with no risk to the operator or the equipment.
