SMA RSB-2S-US-10 Rapid Shutdown Box
SMA Rapid Shutdown Box for US Series Grid Tie Inverters
SMA part number: RSB-2S-US-10
The 2014 National Electric Code (NEC) article 690.12 requires some types of solar systems to have a rapid shutdown system. A rapid shutdown system allows you to immediately shut off the power from the solar panels in emergency situations. This is an important feature for first responders, especially firefighters. SMA has created a very cost-effective rapid shutdown system for use with their US series of grid tie inverters. It only requires two components, the Rapid Shutdown Box and the Rapid Shutdown Controller. The Rapid Shutdown Box (PN: RSB-2S-US-10) is what actually disconnects the solar panels from the electrical system and the Rapid Shutdown Controller (PN: RSC-1X-US-10) is the button switch that activates the box. The RSB self-tests upon startup to ensure it's working properly, which means you never have to worry about malfunctions if an emergency arises. It does not interfere with AFCI detection or operation, and it's UL certified. It comes with MC4 type connectors and snap terminals for fast and easy installation.
