1 O M P O N E N T S High-Speed D ircuit-reakers for Fixed Installation Type UR26, UR36, UR40 & UR46

2 The UR26, UR36, UR40 & UR46 are D high-speed current limiting air ircuit-reakers, trip free, single pole, bi-directional, with electromagnetic blow-out, electric control circuits and direct over-current instantaneous release. Their simple design and high insulation level combined with its compliance to both standards EN50123/IE61992 for fixed installations and EN/IE60077 for rolling stock, guarantee to the UR26, UR36, UR40 & UR46 range a very high reliability and an exceptionally long life time. With its proven worldwide experience and acceptance, Sécheron's circuit-breaker offers you the key product for such a strategic and critical application that is to guarantee the highest safety to your equipment as well as to the people operating it and using it. pplications Line circuit-breaker type* H/L//O for D traction power substations Interconnecting circuit-breaker type* H/I//O for D traction power substations Rectifier circuit-breaker type* H/R,lr,r//O for D traction power substation * Type designation according to standards EN / IE Main features onventional thermal current 2600 (UR26), 3600 (UR36), 4000 (UR40) and 4600 (UR46) Rated operational voltage 900 Vdc, 1800 Vdc, and also 3600 Vdc High rated insulation voltage up to 2300 Vdc or 4800 Vdc Safe with a high insulation level: Over-Voltage category OV4 Pollution degree PD3 Limited maximum arc voltage High rated short-circuit making and breaking capacity Electro-magnetic closing with electric holding or magnetic latch Five double contacts auxiliary switches Low voltage connector for auxiliary contacts and control coil Operational frequency 3 Very low maintenance requirements Proven design with worldwide experience and acceptance Insulation material according to relevant S, NF, STM, IE and DIN standards Designed and tested according to EN /2, IE /2 standards large number of different options to match the various applications requirements reaking current parameters Track line supplied by a rectifier d: duty d - distant fault e: duty e - maximum energy f: duty f - maximum fault current reaking current parameters Îss>1.42Iss I t c f e d Typical duty f haracteristics of the duties d, e and f t c /T Nc d > T Nc [ms] I Ne /I Nss e f I ss /I Nss Iss 0.63 Iss Icut off Id V Ûarc UNe t l di/dt Typical duty e and d t t Iss Îss INss Id Icut off Ûarc UNe di/dt tc tl TNc = Prospective sustained short-circuit current = Peak of Iss = Rated short-circuit current of the circuit-breaker = Setting of maximum current release = ut off current = Maximum arc voltage = Rated operational voltage = Initial current rate of rise = Time-constant of the circuit = Opening time = Rated track time constant of the circuit-breaker 2

3 Opening time t l t l Relationship between opening time tl and the initial rate of rise of current di/dt for direct instantaneous over-current release. Example for an initial rate of rise of current of /s: the opening time is about 3.5 ms for UR26 and about 4.7 ms for UR36 and UR40. Remark: for a shorter opening time the indirect release option can be used (refer to option section). Designation code (standard version) e sure to establish the designation code from our latest version of the brochure by downloading it from our website e careful to write down 21 digits for the type designation code when placing your order. The bold part of this designation code defines the device type and the complete designation defines the identification number of the product, as they are displayed on the identification plate attached to the product. The customer shall write down the setting value Ids in its order form. It can happen that for technical reasons, some configurations of variants and options indicated in the designation code cannot be combined.
