In association with the Current Collector Devices or the pantographs, the Fuse boxes house the 750VDC, 1.500VDC and 2.000 VDC fuses to protect the infeed of the current on-board. Mersen offer a large range of isolated Fuse boxes with the possibility to equip them with advanced technical capabilities integrating smart and connected solutions to enable you to pilot and anticipate your maintenance or energy measurement.
On-board fuse boxes are installed on Metro, trains, catenary less tramway and electric buses. They are a mandatory critical components of protection.
Mersen on-board fuse boxes are designed to be very compact and adaptable to your configurations. They can be converted to connection boxes for connecting electrical cables (see separately).
Mersen have a large library of existing fuse boxes solutions but also Mersen can design, create and customized the box for your application adapting its shape, dimensions and cable connections.
They are reliable and offer low maintenance with a whole life support. They are designed to withstand and answer the shock and vibration and also fire and smoke international regulations.
As they are at the nearest point from the energy source, the fuses boxes are ideally positioned to integrate innovative and connected functions like the Energy measurement.
Mersen will supply you all Spare parts kits to guarantee the reliability and increase the life time of your Fuse boxes including :
Mersen Design team is available to support your design and maintenance team’s especially for the smart and connected functions.
The comprehensive range of Fuse box is designed for all kind of configurations:
They can operate under 750VDC, 1.500VDC and 2.000 VDC.
The principle is simple, Mersen have “naked” (standard sizes and shapes boxes) boxes that you can easily adapt to your configuration:
Mersen fuse box are made with a Sheet Molding Compound (SMC): Polyester resin reinforced with 25% glass fiber, dyed in the mass offering the best ageing characteristics and Higher weatherproof and dust protection.
Mersen offers a large library of compact existing solutions which can be adapted to your solutions (cable entries and exists, kind of cable glands, inside connections, type and quantity of fuses) and avoid Non Recurring costs.
The fuse boxes can house circuits under 750, 1.500 and 2.000 VDC.
The Fuses boxes can be installed in any positions (horizontal, vertical, side) as close as possible from the Current Collector Devices on the bogie or from the pantograph on the train roof.
The fuse boxes can house up to 6 fuses un parallel offering 3.600 Amp.
The fuse boxes can be organised to house 3 different circuits in one single box.
The fuse(s) can be equipped with micro switches to relay the information of the blown status to the Train Management System (TMS).
If the fuses are not equipped with micro switch, the fuse boxes can be equipped with windows to enable the maintenance teams to check the status of the trip indicator of the fuse.
As they are at the nearest point from the energy source, the fuses boxes are ideally positioned to integrate Energy measurement functions.
For security reason, the fuse boxes can be equipped with Voltage detection function in order to prevent the maintenance team of the presence of energy in the box.
Mersen offer the possibility to color them (mass tint or paint).
Mersen can provide the adapted cables to wire you system.
Mersen Service team can train your Maintenance team to make the setting and the maintenance of your installations all around the world.
Beside the spare parts, Mersen can supply the necessary tooling to set perfectly your equipment to the technical requirements of your grid and optimize their use.
Mersen team provide type tests and different studies (Life Cycle Cost, RAMS, FMEA, Eco Design and recyclability, etc…) to secure the reliability of your equipment solution and its conformity to standards and legislations.
