ECO-DRIVE INTEGRATED CONTROL MODULE
ECO-Drive is a compact control module
ECO-Drive integrated with UR circuit breakers, to
manage closing-holding sequences. ECO-
Drive is installed on the UR breaker’s
closing device.
MAIN BENEFITS
D No more additional hardware to manage the closing-holding sequences.
D Reduction of the overall space necessary to operate the circuit breaker.
D Reduction of overall installation costs of the DC circuit breakers.
D Reduction of holding power consumption and operational costs.
D Reduction of the risks of damaging the closing coil during commissioning and service.
LOW VOLTAGE WIRING DIAGRAM
The UR breaker together with the ECO-Drive is fully compliant for elec-
tromagnetic 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

Sécheron proposes 3 different concepts to integrate the UR26/40 circuit
breakers in vehicles:
y Complete Plug & Play roof or underframe-mounted polyester
enclosure, in which the DC circuit breaker is installed, and that
offers an IP54 protection index. It is intended for metros, DC EMUs
and trains.
y Insulation housing with protection index IP00, delivered as
an option separately from the breaker. It enables the car builder
to build its own metal enclosure and/or container with reduced
dimensions, in which the DC circuit breaker with its insulation
housing will be installed. This type is mostly used for locomotives
and trains.
y Complete Plug & Play metal enclosure (DC MODBOX® program),
in which the DC circuit breaker is installed with other functions,
such as current & voltage measurements, line and charging
contactors, charging resistors, disconnect and/or earthing switch.
DC MODBOX® offers an IP56 protection index for outdoor roof or
underframe mounting. This type is mostly used for trains and high-
speed trains, as well as for applications with severe operational
environments (cold and icy, dusty or sandy environments).
