Description

Screw connection technology provides secure and reliable
wire connection.
The integrated current distribution system is another
advantage of the EC 1 12DC… circuit breakers. Wiring can
be implemented easily using available busbar.
The EC 1 12DC… electronic circuit breakers selectively
protect 12 V DC load circuits in hazardous and non-
hazardous environments. A combination of an active
electronic current limit for short circuits and an overload
shutdown ensures that the EC 1 12DC… will quickly react to
an over-current condition in the protected circuit.
Current limitation restricts fault current to 1.5 - 1.8 times the
nominal current rating (I
N
). As a result, the EC 1 12DC… can
prevent the loss of the DC output voltage sometimes
experienced when a faulted circuit triggers a switched-mode
power supply into self-protected output-shutdown mode.
Capacitive loads of up to 75,000 µF can be protected.
The EC 1 12DC… electronic circuit breakers are available
with nominal current ratings from 1 to 10 A. Local status
indication is provided by a multi-color LED, and remote
status indication is available via status output (+12 V = OK).
Manual on/off and reset is accomplished using the
integrated slide switch. Remote reset (EC 1 12DC… S-R)
and remote on/off (EC 1 12DC… S-C) versions are
available.
The EC 1 12DC… can be snapped onto 35 mm mounting
rails (EN 50022) for fast and easy installation. At just
12.5 mm wide, it requires only a small space on the rail.
