1 OMPONNT Highspeed circuitbreakers for Rolling tock Type UR, UR & UR

2 General information UR, UR and UR are highspeed current limiting circuitbreakers with natural cooling, trip free, single pole, bidirectional, with electromagnetic blowout, electric control circuits and direct overcurrent instantaneous release. Of open type construction, the UR, UR and UR can also be delivered with protective enclosure IP for roof or underframe mounting on traction vehicles. These circuitbreakers are primarily designed to protect main and auxiliary circuits of traction vehicles against shortcircuits and overload currents, as well as to connect or isolate these circuits to and from the vehicles power supply. electing the right product for your vehicles requires careful consideration and computing from écheron, for the application load cycle, the environmental temperature and highvoltage cable or busbar section. pplications Protection of electric traction and auxiliary circuits on Metro, MU and LRV vehicles Main features admium free (UR/) onventional thermal current for UR/ (UR designed for heavy applications) and for UR Rated operational voltage 9 Vdc and Vdc Rated insulation voltage Vdc afe with a high insulation level: overvoltage category OV Pollution degree P Limited maximum arc voltage lectromagnetic closing and reduced holding power Optional integrated Orive control module, to manage the closing holding sequences, and to save holding energy consumption and operational costs Optional version High mechanical and electrical endurance: operational frequency Very low maintenance requirements with operations minimum mechanical durability and operations minimum lifetime ompact and light weight Proven design with worldwide experience and acceptance Roof or underframe mounting on the vehicle, when delivered with its protective enclosure Insulation material according to N: Reference standards I/N/ and I/N reaking current parameters Îss Iss I T t m [ms].
