Engineered for Superior Protection

Advanced DC switching technology combining safety, efficiency, and reliability for variable speed drives and inverter applications.

Triple Function Design

Simple and compact solution combining disconnection, protection, and pre-charging in a single device for streamlined installation.

Overcurrent Protection

Offers overcurrent protection for all low-voltage electrical circuits of capacitive loads by limiting high inrush current during circuit power-up.

Automatic Pre-charging

Automatic pre-charging of inverter capacitors managed via coil, eliminating manual intervention and ensuring consistent performance.

Personnel Safety

Double phase isolation (upstream-downstream from the fuse), disconnection, and padlocking capabilities ensure maximum personnel safety.

Maintenance Friendly

Enables maintenance work on part of power system while leaving rest of equipment powered on, reducing downtime and operational costs.

Extended Lifespan

Replace only the fuse - not the entire protection system - to extend installation lifespan and reduce maintenance costs.

Frequently Asked Questions

What makes FUSERBLOC DRIVE different from standard fuse switches?
FUSERBLOC DRIVE combines three critical functions in one device: disconnection, overcurrent protection, and automatic pre-charging of inverter capacitors, providing a complete solution for DC drive applications.
Which current ratings are available for FUSERBLOC DRIVE 1PP?
Four versions are available with rated currents of 630A, 800A, 1200A, and 1700A to accommodate different power requirements for variable speed drives and inverters.
How does the automatic pre-charging function work?
The automatic pre-charging is managed via a coil that controls the pre-charging of inverter capacitors, eliminating high inrush currents and ensuring safe, controlled startup of drives.
Can I perform maintenance without shutting down the entire system?
Yes, FUSERBLOC DRIVE enables maintenance work on part of the power system while leaving the rest of the equipment powered on, minimizing downtime and operational disruption.
What safety certifications does FUSERBLOC DRIVE 1PP have?
The product is certified to IEC 60947-3 and UL98 standards, and is compliant with REACH and RoHS environmental regulations for global market acceptance.
