The VMAX Series VCBs are available at rated voltages of 6.6 to 36 kV, with rated short-circuit breaking capacities from 25 to 40 kA.
SALIENT FEATURES
HIGH RELIABILITY: Testing is performed by an independent testing team. Fully Insulated Design and all the operations are behind the closed doors.All components, such as current transformers, voltage transformers and multifunction relays are made of the highest quality materials.Our new generation design has reduced the number of parts, which reduces the chance of failure.SAFETY: Compartment partitions and an automatic shutter system completely isolate live parts.Comprehensive interlocking mechanisms are used for Safe Operations. MAX VCBs are designed to withstand the huge pressure and burning effect of the arc to withstand in the event of an internal arc fault.HIGH PROTECTION: Specially designed Multiple Protection Relays are installed to provide protection, measurement, communications and control functionality.FLEXIBLE DESIGN FOR EASY INSTALLATION: Flexible features like Readily extensible, Panels with main circuit and control cable entry from either the top or bottom are available for easy installation. Installation and testing duration are considerably reduced as the panel is tested in the factory and then delivered as a complete unit.
