HIGH BREAKING CAPACITY LEVEL MOULDED CASE CIRCUIT BREAKERS (MCCB) DS-3E 1000
AND 1250A-ELECTRONIC TYPE
The feature discriminating electronic circuit breakers from thermal-magnetic breakers is to control the over current releases with electronic
circuits. Electronic control 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.
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 by ambient temperatures.
