1 COMPONENTS High-Speed DC Circuit-Breakers for Title 3 kv DC rolling stock Type UR6, UR36 & UR40

2 General information The UR6, UR36 & UR40 are DC high-speed, current-limiting, circuit-breakers with natural cooling. They are trip free, single pole, bi-directional and equipped with electromagnetic blow-out, electric control circuits and direct over-current instantaneous release. With its simple design and high insulation level, the UR range offers a very high reliability as well as an exceptionally long lifetime. To guarantee a safe and optimized installation of its circuit-breakers in different environments, Sécheron offers a large range of standard and customized solutions. The circuit-breaker of the UR range can be delivered with an insulating housing, for indoor installation or, for outdoor use, in DC MODBOX or in a polyester protective enclosure. pplications 3 kv DC traction vehicles to protect propulsion and auxiliary equipment. DC MODBOX is a modular platform where the DC circuit-breaker is integrated alone or with other high and low voltage components (contactors, disconnectors, resistors, voltage and current sensors ) in a light and compact metal box. This way, rolling stock manufacturers can be supplied with a fully tested Plug & Play unit, easy to install and highly valuable for project management and logistics (refer to brochure SG580044BEN for more details). With its proven worldwide experience and acceptance, Sécheron s circuit-breaker is the key product to guarantee the highest safety to rolling stock material and to the people operating or using it.

6 ECO-Drive integrated control module The ECO-Drive is a compact control module integrated into UR circuit-breakers, to manage closing-holding sequences with electric control. The ECO-Drive is set on the UR breaker s closing device. This option offers to system integrators the following advantages: UR6/36/40 breakers need no more additional hardware to manage the closing-holding sequences Reduction of the overall space necessary to operate the circuit-breaker Reduction of overall installation costs of the DC circuit-breakers Reduction of holding power consumption and operational costs versus conventional holding variant Reduction of the risks of damaging the closing coil during commissioning and service operations The UR breaker together with the ECO-Drive is fully compliant for electromagnetic compatibility with EN and with EN 505: short (10 ms) interruptions class S and 5.1.3: voltage dips / variation (at 0.6Un during 100ms) class C1 Low voltage wiring diagram (Harting connector) + U n - + U EF - k 0 k V bat P V bat N ORDP ORDN ED 4 3 C D Harting connector Customer s scope Sécheron s scope Control circuit technical data Nominal voltage (electric holding only) U n /U EF [V DC ] 4, 36 (), 48 (), 64 (), 7, 110 Range of voltage 6 [ ] Un Idle (standby) power [W] <1.6 Nominal closing power (3) P c [W]/[s] 1 300/1 Nominal holding power for electric holding (3) [W] <8 Nominal opening power for electric holding (3) [W] <1.6 Mechanical opening time on opening order (4) [ms] - 30 Mechanical closing time on closing order (3)(4) T c [ms] ~0 Control voltage U EF and supply voltage U n can be different () Currently under development Concepts for integration on vehicles (3) t U n and T amb = +0 C (4) Starting when the signal is received by the coil Sécheron proposes 3 different concepts to integrate the UR6/36/40 circuit-breakers in vehicles: Complete Plug & Play polyester enclosure, in which the DC circuit-breaker is installed, and which offers an IP54 protection index. It is intended for EMUs and trains outdoor roof mounting (including high speed trains). Insulation housing with protection index IP00, delivered as an option separately from the breaker. It enables the car-builder to build its own metal enclosure and/or container with reduced dimensions, in which the DC circuit-breaker with its insulation housing will be installed. This type is mostly used for locomotives and trains. Complete Plug & Play metal enclosure (DC MODBOX program), in which the DC circuit-breaker is set with other functions, such as current & voltage measurements. DC MODBOX offers an IP56 protection index for outdoor roof or underframe mounting. This type is mostly used for trains and high-speed trains, as well as for applications with severe operational environments (cold and icy, dusty or sandy environment).

Built on a standard platform of rolling-stock-dedicated aluminium enclosure and standard proven high voltage DC components, DC MODBOX can be, to a certain extent, adapted to the application requirements. Typically electric schemes, integrated components, as well as both high- and low-voltage interfaces can be customized. With its limited height (535 mm) and a shape designed to match aerodynamic constraints, DC MODBOX bring efficient solutions to solve co nstraints related to roof space, insulation and speed. Moreover it allows the high voltage DC components to operate protected from the most severe environmental conditions. DC MODBOX simplifies project management, logistics, and installation tasks for the car builder. To evaluate DC MODBOX solution that best suits your project, please contact Sécheron. 7
