NOTICE
Residual current circuit breakers (r.c.c.b.) can be used in
combination with AECs to a limited extent only. An all-current
sensitive residual current relay with leakage current separation
must be used. There are two reasons for this:
1. All rectifier loads (i.e. not just AECs) can produce a direct
2. When radio interference filters are used, high leakage
Interference-free operation with residual current device is guaranteed at a
tripping current  30 mA if the following points are observed:
All-current sensitive residual current devices (Type B acc. to

additional capacitive components between the mains or motor cables and

Unexpected currents
Please note (according to EN61800-5-1): This product, especially
if used in combination with connected components, can cause a
direct current in the protective earth conductor.
 Where residual current devices (RCD) or residual current
monitors (RCM) are used as a protection against direct or
indirect contact, only RCDs / RCMs of Type B are permissible
on the power supply side of this product.

current in the mains cables which can reduce sensitivity
of the circuit breaker.
currents might trip the r.c. circuit breaker too soon which
would result in unwanted failure of the AEC.
