Mersen is providing compact, safe and reliable off-load disconnectors and inverters. These devices offer high performances and robustness for heavy duty requirements with very limited maintenance and whole life of the train.
Mersen offers a large product ranges for On-Board applications under 85VDC, 750VDC, 1,500VDC, 3,000VDC and 25kVAC.
Our standard On-Board disconnector range is rigorously engineered to meet your technical specifications in different configurations (Disconnector, Change-over, Grounding). Mersen has a switch solution that will meet your unique needs.
Mersen off-load disconnectors and inverters are designed to be very compact with a modular and flexible design to meet your electrical circuit configuration.
They can be manually operated from outside the train with the use of a front panel or motorized inside a cubicle.
They are designed to withstand up to 25.000 cycles (open-close) To guarantee this efficiency, Mersen is testing them internally and with external partners.
Mersen will supply you all Spare parts kits to guarantee the reliability and increase the life time of your product.
Mersen Design team is available to support your design and maintenance team’s especially for the smart and connected functions.
Mersen Service team can train your Maintenance team to make the setting and the maintenance of your installations all around the world.
The comprehensive range is divided in three main functions:
They can operate under 85VDC, 750VDC, 1,500VDC, 3,000VDC and 25kVAC.
They are build with a modular and flexible conception where you can choose:
Then you get your customized devices adapted to your technical environments.
The range of Off-load disconnectors, Off-load inverters, Grounding is covering the voltage range of 85VDC, 750VDC, 1,500VDC, 3,000VDC and 25kVAC.
The range of Off-load disconnectors, Off-load inverters, Grounding is covering the current range up to 2000 Amp, for higher rating please ask.
The range of Off-load disconnectors, Off-load inverters, Grounding are studied to withstand 30kAmp short circuit, for higher rating please ask.
This range can offer up to 4 positions (Main Power , Isolate, Work shop, Earth,) and up to 6 poles which can offer different current ratings (for example 1 pole 1250A, 1 poles 800 Amp and 2 poles 250 Amp).
You can customized your device by choosing the following characteristics and functions:
Some disconnectors can be equipped with a spring system named tumbler which have two functions. First function is the speed-up the operation of position change to avoid possible arcing and second is to finish the movement if the motor would miss infeed.
These devices are very low maintenance and last the life time of the train. The first maintenance operation is given for 25.000 operations.
These devices can be equipped with a work shop plug to infeed the auxiliaries circuits when the train is in the depot
Beside the spare parts, Mersen can supply the necessary tooling to set perfectly your equipment to the technical requirements of your network and optimize their use.
Mersen team provide type test and different studies (Life Cycle Cost, RAMS, FMEA, Eco Design and recyclability, etc…) to secure the reliability of your equipment and its conformity to standards and legislations.
