SACE RCQ020/A panel type residual current release (type A)
Tmax circuit-breakers can also be used in conjunction with RCQ020 panel type residual current
relays with separate toroid to be installed on the line conductors ("/A" letter show the necessity to
have on auxiliary power supply).
Thanks to its wide range of settings, the panel relay is suitable for:
Q
applications where the installation conditions are particularly restrictive, such as circuit-breakers
already installed or limited space in the circuit-breaker compartment;
Q
creating a residual current protection system coordinated at various distribution levels, from the
main switchboard to the end user;
Q
where residual current protection with low sensitivity is required, e.g. in partial (current) or total
(time) selective chains;
Q
highly sensitive applications (physiological sensitivity) for protecting people against direct con-
tacts.
Thanks to the 115-230...415V external auxiliary power supply, the RCQ020 panel-type residual cur-
rent device is able to detect current leakage from 30mA to 30A and to act with a trip time that can be
adjusted from instantaneous to delayed by 5s. The opening mechanism is the indirect action type
and acts on the circuit-breaker release mechanism by means of the shunt opening or undervoltage
release of the circuit-breaker itself.
The opening command to the circuit-breaker (Trip delay) can be temporarily inhibited, and the cir-
cuit-breaker can be opened by remote control by means of the RCQ020 device.
The following equipment must be requested when ordering:
Q
the RCQ020 device;
Q
an opening coil (SOR) or an undervoltage release (UVR) of the circuit-breaker to be housed in the
relative slot made in the left pole of the circuit-breaker itself;
Q
a closed toroid, that can be used for cables and busbars, chosen from amongst those available,
with a diameter from 60mm to 185mm.
