The 3VA series by Siemens will renew the Sentron portfolio of molded case circuit breakers for low voltage power distribution. The new, more compact circuit breakers are available in a variety of versions up to 630 A, and represent a particularly space-saving solution.
The new 3VA molded case circuit breakers come equipped with an integrated metering function for the capture of energy data.
With an extensive range of over 500 accessory components, the 3VA MCCB can be expanded with more than 70 additional functions.
New are the integrated metering function, a switch disconnector version, and MCCBs with a side wall mounted rotary operator. An online product configurator and twelve downloadable CAx data types, including 3D models and EPLAN macros, help facilitate the engineering of the protective devices. The 3VA series comes with over 500 accessory components for a modular configuration meeting virtually any requirement, plus more than 70 additional functions.
MCCBs protect electric lines and electric consumers, as well as entire industrial systems in buildings and industrial facilities from damage and failures by safely disconnecting the power supply in case of faults like short-circuit or overloads.
“Our new 3VA series is a highly versatile MCCB system that supports every engineering step from initial planning to running operations. Our customers find optimized solutions for any area of application, and at the same time save time and money”, explains Andreas Matthé, CEO of the Siemens business unit Low Voltage & Products.
MCCBs rank among the most important safety components in low voltage power distribution: An estimated 30 million MCCBs are installed each year around the globe in a great variety of technical environments, including large-scale residential and non-residential complexes and manufacturing facilities. MCCBs are increasingly assigned additional operational tasks, e.g. the capture of power usage data.A Modular System for Virtually Any Requirement
The 3VA2 series is designed for use in applications with higher technical requirements. In addition to an increased switching capacity of up to 150 kA, these MCCBs come with an electronic trip unit (ETU), and an integration capability for metering and communication functions, as well as excellent selectivity properties for high system availability.Less Energy Costs
The intuitive and ergonomic device design, combined with integrated indicators and displays, ensures a comfortable and safe operation of the MCCB. The switch position of MCCB with manual operating mechanisms is clearly visible at all times; an optional illumination kit helps support visibility in poor light conditions. Unauthorized switching is prevented with front or rear-mounted locking options.
Internal accessory modules can be installed in all model sizes. Mechanical and color coding on each module eliminates erroneous application. Modules are simply plugged into their clearly coded accessory ports and connected.Faster Configuration: Up to 80 Percent Time Savings
