CTC: NEW technology for protection of PV installations!

CITEL, the experts in surge protection, takes protection of photovoltaic installations (PV) to a whole new level!

Designed with innovative CTC technology, your PV installation will be protected even more effectively and reliably against damage caused by surges.

The innovative and patented CTC-Technology (Central Thermal Control) is an entirely new innovation in disconnection technology.

Designed with CTC, next generation PV SPD are safer, faster, and more compact than previous generation designs. This new cutting-edge technology has been awarded numerous patents for CITEL.

CTC improves upon legacy disconnection technology designs primarily through:

• Its thermo-sensitive solo separation point, which is centrally located within SPD
• additional insulating safety barriers have been integrated into the isolating device for more reliable separation of the poles in the event of separation.

**This game-changing technology result in new PV SPD design benefits **

• Space saving due to more compact design
• Short conductor lengths between MOV and cut-off device
• Fast triggering of the cut-off by cumulative heat impact of all MOVs on one heat point
• Additional insulation barrier for even safer pole separation
• All-pole disconnection in case of tripping
• No risk of varistor short circuits
• Much lower temperature of the SPD envelope during disconnection providing more safety
• For the user or side by side electrical devices
