ABB Rapid Shutdown device, RS1-1PN6-MC4

ABB, Rapid Shutdown Box, 600V, One Input-One Output Strings, 25A Max, NEC 690.12 & NEMA4X, R1-1PN6-MC4-KIT

ABB now offers the a low-profile behind the module rapid shutdown solution for 600V systems. This product provides a fail-safe solution for emergency respondents 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. The Rapid Shutdown box can moutn directly to the PV mounting rail or PV module 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 and driven rain.

Two models are available to cover all system configurations; including a single input/output version and a two-input/two-output version. 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 the ABB's dual MPPT inverter channels, while the single output box is perfect for small PV arrays utilizing one MPPT channel or system requiring two rapid shutdown boxes. To further reduce system cost, the input channels are rated up to 25A allowing paralleled strings on one input.
