Electronic Trip Circuit Breaker Basics: Schneider Electric Micrologic
Schneider Electric Micrologic Electronic Trip units. MICROLOGIC electronic trip circuit breakers can help optimize coordination: Independent adjustments - allow one dial setting to be changed without affecting the rest of the pickup and delay levels. This allows the designer to better define the tripping characteristics needed on the system.
The essence of LV circuit breakers
The electronic trip unit makes many possible trip settings available for Function L, more precisely, a bundle of parallel lines. Each line is identifed by a time t1 (the long time delay) which represents the trip time of the protection, in seconds, in correspondence with a multiple of I1.. For example, this multiple depends on the trip unit and is equal to 3 × I1 for ABB's breaker type ...
