Air Circuit Breakers (ACBs) and high-capacity frame MCCBs. Annexes and Specialized Protections
Specifies testing conditions for breakers installed in ungrounded (IT) networks, where individual phase-to-earth faults present unique operational challenges.
The standard IEC 60947-2 applies to circuit-breakers used in various applications, including:
IEC 60947-2 is a specific part of the broader IEC 60947 series, published by the International Electrotechnical Commission. While Part 1 covers general rules for low-voltage switchgear, operating up to 1,000V AC or 1,500V DC.
