COMPONENTS
High-speed DC circuit-breakers
for fixed installations (EN / IEC standards)
Type UR
General information
The UR range of DC circuit-breakers has achieved worldwide
acceptance as a well proven design for use in fixed installations.
It has been regularly upgraded and adapted to new standard
requirements and for different applications over the years,
continuously improving the level of performance and functionality.
These have led to an impressive service track record throughout
the world for the UR product range. Combining a compact
design with a high making and breaking capacity, the UR range,
with its low number of parts also guarantees high reliability and
low maintenance requirements.
Applications
• Line circuit-breaker for DC traction power substations
• Interconnecting circuit-breaker for DC traction power substations
• Rectifier circuit-breaker for DC traction power substations

Main features
• Conventional free air thermal current covering a range from 2’600 A to 8’000 A
• Rated operational voltage 900 VDC, 1’800 VDC and 3’600 VDC
• Safe with a high insulation level
• Indoor installation
• Bi-directional or uni-directional overcurrent release
• Trip-free direct acting device
• High rated short-circuit making and breaking capacity
• Limited maximum arc voltage
• Electro-magnetic closing with electric or magnetic holding
• Optional integrated ECO-Drive control module, to manage the closing - holding sequences, and to save holding energy consumption
and operational costs
• Large number of different options to match the various application requirements
• Very low maintenance requirements with high electrical and mechanical endurances
• Simple design with few moving parts resulting in high reliability
• Proven design with worldwide experience and acceptance
• Reference standards: IEC77, EN50123-1 /-2 ,IEC61992-1 /-2
• Also available according to IEEE (ANSI) C37.14 / C37.16 standards (refer to our specific SG104309BEN brochure)
• Insulation material according to relevant BS, NF, ASTM, IEC and DIN standards

Start of the closing pulse: the E contacts close.
Closing pulse: 0.5 to 1 s, then the E contacts open.
Holding: achieved by the permanent magnet.
Opening: the F contacts close to provoke a current pulse of
the opposite polarity to the closing current. The duration of
this pulse is 0.5-1 s, then the F contact opens. The opening
current is 20 % of the closing current.

ECO-Drive integrated control module— UR26/36/40/46
ECO-Drive is a compact control module integrated with UR circuit-breakers, to manage closingholding sequences with electric control. ECO-Drive is set on the UR breaker’s closing device.
This option offers to system integrators the following advantages:
• UR26/36/40/46 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 50121-3-2 and with EN 50155: § 5.1.1.2 short (10 ms) interruptions class S2 and § 5.1.3:
voltage dips / variation (at 0.6Un during 100ms) class C1

Position indicator — UR26/36/40/46/60/80
A mechanical position indicator actuated though a rod linked
to the circuit-breaker moving contact gives the position of the
breaker: 0 = OPEN while I = CLOSED
BIM indirect release (shunt trip) and manual release
The indirect release enables to shorten the opening time when required by specific application. The choice of the relevant type has to be
validated by Sécheron prior quoting. This device can also be manually activated.

Manual release
Manual releases are safety devices designed to guarantee that the breaker is in OPEN position so as to access the breaker’s panel -e.g.
for maintenance.
The vertical release is automatically actuated while withdrawing from the panel the trolley on which the breaker is installed.
The horizontal release must be manually actuated from the front side of the panel door before opening it.

Manual closing device
The manual closing device, mainly used for maintenance operations, enables to close and open the circuit-breaker without low voltage
supply and under no load.

Contact wear indicator (WI) or overcurrent release detector (I>) — UR26/36/40/46
Installed on the rear side of the circuit-breaker closing device,
these options monitor the position of a rod linked to the breaker’s
moving contact, which rod actuates a micro-switch.
Based on the selected configuration the detector informs about:
- the reaching of the wear limit of the main contacts of the circuitbreaker: function ‘’contact wear indicator’’.
- the tripping of the circuit-breaker through the over-current
release: function ‘’over-current release detector’’.These two
functions cannot be selected together.
Designation code for ordering
Designation code information
• Be sure to establish the designation code from our latest version of the brochure by downloading it from our website
“www.secheron.com”.
• Be careful to write down the complete alphanumerical designation code with 22 characters when placing your order.
• The customer shall write down the setting value Ids in its order form.
• For technical reasons some variants and options indicated in the designation code might not be combined.
• The bold part of this designation code defines the device type, and the complete designation defines the identification number of
the product, as displayed on the identification plate attached to the product.
