Schneider EasyPact MVS 06-40 Air Circuit Breaker

The Schneider Electric EasyPact MVS06–MVS40 Air Circuit Breaker (ACB) is designed for low-voltage power distribution systems, providing circuit protection and switching functions for high-current electrical applications. Covering rated currents from 630 A to 4,000 A, the series offers multiple frame sizes and breaking capacity options to meet different installation requirements. With electronic ET, ETA and ETV trip systems, flexible mounting configurations and a range of operating accessories, EasyPact MVS supports reliable power distribution in industrial and commercial facilities.

Electronic Protection and Trip Unit Functions

The EasyPact MVS series is equipped with ET, ETA and ETV electronic trip systems, offering different levels of circuit protection and electrical measurement. Depending on the selected trip unit, protection functions include long-time overload protection, short-time and instantaneous short-circuit protection, and ground-fault protection. ETA and ETV versions also provide electrical measurement capabilities, with ETV supporting both current and energy measurements. These functions help operators monitor electrical conditions and manage power distribution more effectively.

Flexible Installation and Operating Configurations

Available in fixed-mounted and drawout versions, the EasyPact MVS06–MVS40 series can be integrated into different low-voltage switchboard designs. Three-pole and four-pole configurations provide flexibility for various power distribution systems. Drawout models feature connected, test and disconnected positions, facilitating circuit isolation, inspection and maintenance. The stored-energy operating mechanism supports manual or electrical operation, with compatible accessories available for remote opening, closing and status indication.

Breaking Capacity and Protection Coordination

The EasyPact MVS range offers different breaking capacity versions to accommodate varying short-circuit levels in electrical distribution networks. Its electronic trip systems provide adjustable protection settings to support coordination between upstream and downstream circuit breakers. Depending on the selected configuration, short-time protection and zone-selective interlocking (ZSI) functions can help improve protection selectivity and reduce unnecessary interruptions across the distribution system.

Applications

The EasyPact MVS06–MVS40 Air Circuit Breaker is suitable for main incoming protection, outgoing feeder protection and bus-coupler applications in low-voltage electrical distribution systems. Typical installations include industrial plants, commercial buildings, infrastructure projects, power distribution panels and large electrical switchboards requiring high-current switching and circuit protection.
