IntroductionCircuit Breakers with Electronic Over Current
Release:The feature discriminating electronic circuit breakers
from thermal-magneticbreakers is to control the over
current releases with electronic is circuit. Electronic
iscontrol is performed via microprocessor.During design of the
electronic circuit,worst possibilities to encounter
in operation have been taken into consideration. In high
circuit currents, direct opening has been ensured
without operating electronic circuit. In this
way, possibility of failure in the electronic circuit has
been eliminated.-Maximum, minimum, average etc. Values of the
drawn current at various time intervals (day-night) can be
taken.Rated and Instant opening current adjustment areas of
electronic circuit breakers are quite wide. This
feature allows wide use opportunity to the
breaker Furthermore, electronic circuit
breakers are not affected from
ambient temperatures.Advantages°Wide range:800A to
1600A(AC)°Compact dimensions°Adjustable thermal
setting(40-100%)In.°Adjustable magnetic
setting(1.5-12times)In.°Push to trip button provision.°Separate
main and arcing contacts°Wide range of accessories.
