ABB RS2-2PN6-KIT 2-String Combiner Box w/ Disconnect Switch

ABB, Rapid Shutdown Combiner Box with Disconnect Switch, 2x2 Max Strings In - 2 Combined String Out, 11.25 A per String, 600 Volts, NEMA 4X, RS2-2PN6-KIT

ABB now offers the only family of rapid shutdown products for string inverters today.This product provides a fail-safe solution for emergency responders to eliminate voltage at the PV array in compliance with NEC 2014 Rapid Shutdown code requirements.

The ABB Rapid Shutdown system requires no extra conduit; minimizing additional material cost and associated labor. Shutdown occurs at the rooftop box
when utility power is lost or when the PV system’s AC disconnect switch is opened. In jurisdictions requiring a dedicated activation switch, an optional
emergency stop button is available. The Rapid Shutdown box can mount directly to the PV mounting rail and lay parallel to the roofing surface. The NEMA 4X design permits installation angles from 0-90° while maintaining its water-tight seal from mounted snow or driven rain.

Three models are available to cover all system configurations; including, a two-string pass through, a two-string combined and a four-string combined box. The unique features of each box can be used to maintain the specific configuration of the PV system. Dual outputs in the box maintain the benefits of ABB’s dual MPPT inverter channels, while the single output box is perfect for small PV arrays utilizing one MPPT channel or systems requiring two rapid shutdown boxes. To further reduce system cost, string combining models reduce the number of output conductors between the rooftop box and the inverter. The applicable rapid shutdown boxes include disconnect switches to comply with NEC 2014 690.15(C) Direct-Current Combiner Disconnects .

Features

• Highlights - Meets NEC 690.12 while avoiding the cost of additional conduit making this solution the most cost-effective rapid shutdown product available. Immediately eliminates voltage and current upon activation. NEMA 4X enclosure provides added protection from the harshest rooftop conditions. Multiple string combining models available provide additional savings by reducing the number of DC conductors to the inverter. Equipment disconnect included in string combining models provide safety and compliance with NEC 2014 combiner-disconnect requirements.
