Function
FUSERBLOC DRIVE units with manual front operation are multipole DC fuse combination switches.
They guarantee overcurrent protection for any low voltage electrical circuit with capacitive loads by limiting the high inrush current during circuit power-up and are designed to allow maintenance work on DC/AC variable speed drives or PV inverters without shutting down the entire installation.
The range is available in direct and external operation, with 2 power poles + 2 pre-charge poles*, up to 1600 A.
*Contact us for version with 1 pre-charge pole and/or UL version

Advantages
Simple and compact
The FUSERBLOC Drive is the most compact and simplest solution on the market for variable speed drives under a common DC bus. This product combines 3 functions: disconnection, protection and pre-charging in a single device.
Automatic pre-charging
After maintenance operations, the pre-charging of the inverter capacitors is managed automatically via a coil.
In addition, the opening of the pre-charge poles and the closing of the power poles is also done automatically.
Optimised maintenance
This multifunction device enables maintenance work to be done on part of the power system while leaving the rest of the equipment powered on.
Optimum safety
Double phase isolation (upstream-downstream of the fuse), disconnection, and padlocking guarantee total operator safety during fuse replacement.
The device is capable of maintaining the OFF, pre-charge or ON position in the event of power failure.
Applications
- Industry - Protection for drives and motors
Environmental data
RoHS compliant
