Conformity to standards Function SIRCO PV UL98B are manually operated multipole load break switches. They make and break on load and provide safety isolation for any PV circuit up to 1000 VDC (as per UL98B standard). They comply with NEC Art. 690 (US National Electrical Code) concerning photovoltaic installations. They are compliant for use within solar inverters and enclosures governed by UL1741 standard. 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 such as earthing, floating or bipolar. > UL98B Guide WHVA, file E > CSA C22.2#4, Class , file > NEC Art 690 Issue 2011 > IEC Approvals and certifications (1) 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 with current interruption of up to 2000 A. Back-to-back double load break switch Back-to-back double switches enables: - simultanuous on load operation of two switches with a single handle, - a compact solution when connecting two separate photovoltaic circuits compared with the use of two separate switches, - easy connection, - voltages above 1000 VDC are safety broken by the use of two poles in.

Accessories External operation Use In a combiner box, located close to the solar cell strings, or located close to the inverter, we recommend to use a door interlocked external handle for its safety

Example The locking function of the enclosure in the "ON" position will force the operator to safely disconnect and isolate the solar cell strings prior to any intervention.

The interlocking function is restored when the door is closed back.

6 Accessories External operation Use In a combiner box, located close to the solar cell strings, or located close to the inverter, we recommend to use a door interlocked external handle for its safety features. Door interlocked external operation handles include an escutcheon, are padlockable and must be utilised with an extension shaft. Example The locking function of the enclosure in the "ON" position will force the operator to safely disconnect and isolate the solar cell strings prior to any intervention. Opening the door when the switch is on "ON" position is possible by defeating the locking function using a tool (authorized persons only). The interlocking function is restored when the door is closed back. acces_150_a_2_cat S2 type handle acces_236_a_2_cat Reinforced S2 type handle Handle type Handle colour NEMA degree of protection Reference B4 B5 - B4 DS S2 Black 142F , 3R, 12 B4 B5 - B4 DS S2 Red/Yellow 142G 2111 B4 B5 - B4 DS S2 Black 142D 2111 B4 B5 - B4 DS S2 Red/Yellow 142E 2111 B5 DS - B6 S3 Black 143D , 4X B5 DS - B6 S3 Red/Yellow 143E 3111 B7 S4 Black 144D 3111 B7 S4 Red/Yellow 144E 3111 B6 DS B7 DS V1 Black 1, 3R, acces_166_a_2_cat acces_152_a_2_cat access_189_a_2_cat S3 type handle S4 type handle V1 type handle Shaft for external handle Use Standard lengths: in / 200 mm, in / 320 mm, in / 400 mm.
