1. Congratulations on purchase of your RPCM!
Dear Customer!
Please accept our congratulations on your purchase of RPCM - Resilient Power Control Module.
This device will allow you to be in control of your power supply infrastructure with great user
experience.
We have paid a lot of attention to craft the device the way we would want it to be for ourselves. In
many ways, physically, ergonomically, architecturally, electrically it is designed to be one stop shop
for many power control tasks that people meet in many circumstances.
We have made every effort to make RPCM useful both in enterprise environment behind firewall and
in less strict environment with access to Internet, where all the power of the Cloud comes to your
service.
We have tried to make interfaces as intuitive as possible and prepared detailed documentation to
assist you in every case that may be not obvious or expected for this class of equipment.
Bon voyage! We hope you enjoy it!
2. General review:
Models RPCM 3x250 and RPCM DELTA are designed for installation with 3 (three) phase input
power lines.
RPCM 3x250 is designed for input current 250A and RPCM DELTA — for input current 467A.
RPCM 3x250 is connected in WYE mode (415V/240V), via 3 phase buses, neutral bus and
protective ground bus.
RPCM DELTA is connected in DELTA mode (208V), via 3 phase buses and protective ground bus.

Note. For RPCM 3x250 and
DELTA, the short-circuit current is
3 iNom or 75 A.
To ensure selectivity, the circuit
breakers at the inputs must be
selected so that the tripping does not
occur at short-circuit currents
< 75A, the lower threshold of the
tripping current of the upstream
circuit-breakers must be chosen so
that the tripping does not occur at
the short-circuit current at the
consumer connection point. To
ensure complete selectivity, the use
of selective circuit breakers with a
trip delay at short circuit 10ms is
recommended.
