Advantages
High-performance switching
SIRCO MOT DC motorized load break switches incorporate patented technology, providing a breaking capacity at 1500 VDC with just 2 poles, significantly limiting power dissipation.
Application tested design
Designed and tested for several DC applications, with proven performance in the harshest of environments. The arc extinguishing system provides safe disconnection, rapid arc extinguishing, and current interruption.
- Tested against high short circuit systems with and without fuse protection to ensure complete system protection.
- Proven against severe environmental factors including: “Annex Q level C according to IEC” salt spray tested, high temperature and altitude, humidity cycle tested.
Reduced total cost of ownership
Developed with user cost savings in mind, the product features improvements that ensure a lower total cost of ownership.
- Flexible wiring configurations allow for simple in and out wiring, and by not using series bridging bars, cost savings can be achieved.
- One design for both UL and IEC products providing the same base design for customers with UL and IEC machines.
- Compact solution with reduced footprint and weight improves sustainability with reduced packaging, transportation, and installation costs.
