SIRCO PV UL98B

from 100 to 3200 A, up to 1500 VDC

SIRCO PV UL98B are manually operated multipolar disconnect switches. They make and break under load conditions and provide safety isolation for any PV circuit up to 1000 VDC (as per UL98B standard) and 1500 VDC (as per IEC 60947-3). They comply with NEC Atr. 690 (US National Electrical Code) concerning photovoltaic installations. They are compliant for use within solar inverters and enclosures governed by standard UL1741.
SIRCO PV are extremely durable switches that have been tested and approved for use in the most demanding environments.
They have been designed and tested for all types of applications: Grounded, floating or bipolar.

Advantages

Performance

A glass fibre reinforced polyester break chamber with an arc extinguishing system provides a patented safety disconnection system offering rapid extinguishing of the electric arc up to 1500 VDC and current interruption up to 2000 A.

Back-to-back double disconnect switch

The system of back-to-back double switches enables:
- on load operation of two switches with a single handle,
- compact solution when connecting two separate photovoltaic circuits compared with the use of two separate switches,
- easy connection,
- voltages above 1000 VDC are broken by the use of two poles in series.
