COMPONENTS
High-speed DC circuit-breakers
for Fixed Installation (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 different applications over the years, continually
improving the level of performance and functionality.
This has 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

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