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.

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 Low voltage wiring diagram (Harting connector) ED k0 Un + k1 + UEF - 28 26 19 17 15 13 11 9 7 5 3 1 Harting pin number Vbat P 25 27 Vbat N 4 22 ORDP 3 21 ORDN C Customer’s scope Sécheron’s scope D 20 18 16 14 12 10 8 6 4 2 Technical data Control circuit Nominal voltage (electric holding only) (1) Un/UEF [VDC] Range of voltage Idle (standby) power Nominal closing power 72, 110 [ 0.7 - 1.25 ] Un (2) Pc Nominal holding power for electric holding (2) Nominal opening power for electric holding (2) Mechanical opening time on opening order (3) Mechanical closing time on closing order (2)(3) Tc (1) Control voltage UEF and supply voltage Un can be different At Un and Tamb = +20°C (3) Starting when the signal is received by the coil (2) 13 [W] <1.6 [W]/[s] 1’300/0.5 [W] <8 [W] <1.6 [ms] 15 - 30 [ms] ~150 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.

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. for UR26/36/40/46 vertical release for UR60/80 horizontal release vertical release horizontal release actuation actuation actuation actuation 14 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. for UR26/36/40/46 for UR60/80 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.
