2 AC CIRCUIT-BREAKER FOR ROLLING STOCK, TYPE MACS

GENERAL INFORMATIONMACS is Sécheron’s main circuit breaker platform for installation on AC rail vehicles. It offers car builders a highly modular platform which is ideally suited to their various applications and requirements.MACS can be mounted vertically on the roof of EMUs and Trains, as well as inside the high voltage compartment of locomotives. To limit roof cut-outs, as well as noise transmission, MACS can also be supplied with optional roof box. Another option is horizontal installation inside Sécheron’s high-voltage compact modular enclosure, AC MODBOX®, either on the roof or under the chassis.

MACS is a fully electrically operated circuit breaker, designed to automatically open through spring release if the low voltage supply is interrupted. This fail-safe concept is a key safety benefit for electrically operated rolling stock circuit breakers. The MACS lightweight platform with its modularity and compact dimensions, as well as the AC MODBOX® allowing MACS to be integrated with other high voltage functions such as current and voltage meas-urements, disconnect switch, filters, and transient inductors in a compact aluminium housing, are perfect solutions for your rolling stock running on 15 kVAC and/or 25 kVAC networks.

/// VERTICAL MOUNTING ON THE ROOF (WITH ROOF CUT-OUT)

MOUNTING POSSIBILITIES

With this solution a roof cut-out is required for the MACS low voltage compartment as well as for the manual operating mech-anism of the earthing switch.

To avoid roof cut-out while reduc-ing structural noise transmission, MACS can also be delivered to-gether with Sécheron’s optional roof box.

/// AC CIRCUIT BREAKER AND SURGE ARRESTER CONNECTIONS

For safe and efficient protection against lightning and switching overvoltages, Sécheron strongly recommends the use of two surge arresters SA1 and SA2 in the vehicle’s high voltage circuit. In order to effectively protect the AC circuit breaker, the distance between each surge arrester and the AC circuit breaker must not be too long. Customers wishing to add a surge arrester to the MACS can rely on Sécheron’s specialists to specify the most appropriate type.

For more information about the MODBOX® program, please refer to brochure SG580044B.

The Sécheron AC MODBOX® enclo-sure includes our AC circuit breaker type MACS and various high- and low-voltage components. The compact, smart enclosure ensures safe and efficient integration of high-voltage components in vehicle roof or vehicle under-frame installations. Each AC MODBOX® is engineered and configured to meet the needs of your project, taking into account integrated functions and interfaces with the vehicle. We primarily use Sécheron components and can include other devices from best-in-class suppliers to provide you with a turnkey solution.

With its limited height (535 mm) and a shape designed to meet aerodynamic requirements, AC MODBOX® offers efficient solutions to roof space, insulation and speed constraints. It also provides the high-voltage AC components with protection from the most severe environmental conditions in their operation. AC MODBOX® simplifies project management, logistics, and installation tasks for the car builder.
