Description

The EC 1 12DC… electronic circuit breakers selectively

protect 12 V DC load circuits in hazardous and nonhazardous

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 (IN). 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.

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.
