DANSK DSF/PREN IEC 60947-2 PDF

This document applies to circuit-breakers, intended to be installed and operated by instructed or skilled persons, the main contacts of which are intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V AC or 1 500 V DC; it also contains additional requirements for integrally fused circuit-breakers. This document also applies to circuit-breakers with multiple ratings below and above 1000 V AC, but not exceeding 1500 V AC. It applies whatever the rated currents, the method of construction or the proposed applications of the circuit-breakers may be. Circuit-breakers per this document are suitable for isolation. The requirements for circuit-breakers which are also intended to provide earth leakage protection are contained in Annex B. Additional requirements for circuit-breakers intended for connection of aluminium conductors are contained in Annex D. The additional requirements for circuit-breakers with electronic overcurrent protection are contained in Annex F. The additional requirements for circuit-breakers for IT systems are contained in Annex H. The requirements and test methods for electromagnetic compatibility of circuit-breakers are contained in Annex J. The requirements for circuit-breakers not fulfilling the requirements for overcurrent protection are contained in Annex L.
