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.

Relationship between opening time tl and the initial rate of
rise of current di/dt for direct instantaneous over-current
release.
Example for a di/dt of 3x106 A/s:
- for UR26:
tl ~ 4.3 ms,
- for UR60/80:
tl ~ 4.1 ms.
Note!: for a shorter opening time on low di/dt, the “indirect release”
(shunt trip) option can be used (refer to “Options” section page 12).

ECO-Drive integrated control module— UR26/36/40/46
ECO-Drive is a compact control module integrated with UR circuit-breakers, to manage closing-holding sequences with electric
control. ECO-Drive is set on the UR breaker’s closing device.
Key benefits
This option offers to system integrators the following advantages:
ECO-Drive
--------
No need of additional hardware to control the breaker
Compact integration
Reduction of overall installation costs
Reduction of operational costs with lower power consumption
Reduction of the risks to damage the closing coil
Full compliance with EN50121-3-2 standards for EMC
Full compliance with EN50155 § 5.1.1.2 class S2 (short interruption of voltage supply)
-- Full compliance with EN50155 § 5.1.3 class C1 (supply change over)
Note:
Available for UR26/36/40/46
Available for closing device with E-type holding

BIM indirect release (shunt trip) with integrated 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
circuit-breaker: 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 of maximum current release value (Id) 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. ​
