Function

SIRCO MOT DC are remotely operated multipolar disconnect switches.
They make and break under load conditions and provide safety isolation for any low-voltage circuit dedicated to DC/PV applications up to 1500 VDC.

Conformity to standards

UL 98A, Guide WHVA File E346418
UL 98B, Guide WHVA File E346418
IEC 60947-3

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.
