AC CIRCUIT-BREAKER FOR ROLLING STOCK, TYPE MACS2
GENERAL INFORMATION
APPLICATIONS
MACS is a platform for Main AC Switch installed on electric rail vehicles running on AC networks. The AC vacuum Circuit-Breaker (AC VCB), which is the core function of the assembly, can be combined on the same base plate with other functions, such as Earthing Switch (ES), Surge Arrester (SA), Roof Switch (RS), offering the car builders the most modular platform, particularly well adapted to match their different applications and requirements.
MACS can be mounted either vertically on the vehicle’s roof of EMUs and Trains as well as inside traction container for locomotives. Another option is horizontally inside Sécheron’s high voltage modular compact enclosure, AC MODBOX®, to be installed on the roof- or under the frame of trains.
MACS is a fully electrically operated circuit-breaker, designed to automatically open through spring release in case the low supply voltage is interrupted. This fail-safe concept is a key safety issue for rolling stock circuit-breakers, equipped with electric or electro-pneumatic operation.
MACS platform with its small dimensions and light weight, completed with the compact and modular AC MODBOX®, which integrates MACS in an aluminium housing with other high voltage functions such as current and voltage measurements, disconnect switch, filters, transient inductors, is the perfect solution for your rolling stock material running on 15 kVAC or/and 25 kVAC networks.
• Switching and protection of main and auxiliary electric circuits for locomotives, trains and EMUs running on 15 kVAC or/and 25 kVAC networks.
MAIN FEATURES• Compact multi-functional switch including: AC
circuit-breaker, earthing switch (option) and surge arrester (option) on a single support of 940 mm x 430 mm.

For a safe and efficient protection of the vehicle’s high voltage circuits against ligthning and switching overvoltages, Sécheron strongly recommends to use two surge arresters SA1 and SA2 in the high voltage circuit of the vehicle.
In order to protect efficiently the AC circuit-breaker, the distance between each surge arrester and the AC circuit-breaker must not exceed 15 meters.
Should the customer want to integrate one surge arrester to the MACS, he can rely on Sécheron’s specialists to define the appropriate type.

Surge arrester connections: M12 screws.The connection between the ac circuit-breaker and the surge arrester is not represented on the drawing but is available in the scope of supply from Sécheron.
