DOWE BTR-2 Series 250a / 400a / 630a 3p Netral Fuse Base Low Voltage Vertical Fuse Rail And Fuse Base For Busbar
The latest conjoined type switch safely closes three-phase circuits with a fuse handle, has a flame-retardant base (IP30), supports quick installation, and reduced wiring. It offers 100kA breaking force, operates at 1.3 times the rated current, and can include a fuse monitor, signal switch, and remote control module.
1. Conjoined type can be a three-phase closed off simultaneously
2. Operation safely. while fuse installed in the handle and it can be used as a contact blade directly.
3. It is beautiful and practical and the whole switch can be disassemblyed easily. and installed in the cabinet fastly.;
4. Wiring reduced make it easy to increase the loop and the utilization of the cabinet;
5. The resin glass fiber base (BMC-UP(GF15 ). FR/DMC-2).with flame retardant grade. and the enclosure rating up to IP30;
6. The latest product has highest usage in the market.;
7. The instantaneous breaking force is up to 100kA. and the operating capacity with a load can be up to 1.3 times of the rated current;
8. It can be with the fuse monitor. signal switch and a remote control module.
