Special characteristics
There are two different functional types of side mounted residual current device, i.e. the
RCD310 and the RCD510. The differences in functionality between these two types are
explained by the list of features below.
●
Time delay:
–
RCD310 without time delay (instantaneous)
–
RCD510 with an adjustable delay time
Δt from 0 to 3000
ms
●
Number of poles:
–
RCD310 is available only in a 4-pole version
–
RCD510 is available in 3-pole and 4-pole versions
●
Rated operating current:
–
RCD310 available only up to 160 A (3VA11)
–
RCD510 available up to 250 A
●
Supplied connection technology:
–
RCD510 (3VA12 molded case circuit breaker) is supplied with the necessary
connection components (1 set of box terminals).
Advantages
●
Slimline, side mounted design (30 mm) leaves space for other components in the
distribution board.
●
The residual current devices, the 3VA1 molded case circuit breakers and the 3VA1 switch
disconnectors all have a cover size of 45 mm, so that they are easy to install, for
example, adjacent to miniature circuit breakers in a distribution board.
●
With the DIN rail adapter accessory installed, RCD310 and RCD510 units up to 160 A
can be mounted easily on a DIN rail.
The side mounted residual current devices also feature a screw mounting option so that
they can be attached directly to a mounting plate.
