main product features:
1. the integrated isolation circuit breaker is mainly composed of isolation circuit breaker, grounding switch and mechanical interlocking system and can integrate electronic current transformers and intelligent modules. it is one of the most important equipment in the new generation of intelligent substations. it meets the requirements of iec 62271-1 and iec 62271-100.
2. isolation circuit breaker replaces traditional open circuit breaker and isolation switch, realizes function combination, reduces equipment quantity, improves reliability, reduces failure rate and reduces maintenance quantity. it can save about 50% more space than the traditional layout.
3. this product is the world's first intelligent isolation circuit breaker that has passed the class e2 short circuit combination function test, leading the world in technical level.
