Rapid Shutdown for 600V applications
The second generation ABB rapid
shutdown solution for 600V systems
is even easier to implement. This
behind the module product provides
a fail-safe solution for emergency
responders to eliminate voltage at
the PV array in compliance with NEC
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 mount
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 snow and 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 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, the input
channels are rated up to 25A allowing paralleled
strings on one input.
Highlights:
• Meets NEC 690.12 while avoiding the cost of
additional conduit making this solution one of the
most costeffective rapid shutdown product
available
• NEMA 4X enclosure provides added protection from
the harshest rooftop conditions
• The 25A rated inputs allow for paralleled strings to
provide additional savings by reducing the number
of DC conductors to the inverter
• New low-profile, behind the module design
improves the look of theoverall system by keeping
wire management behind the array
• Second generation design is even easier to install
eliminating the crimp tool used with generation one.
