DZ10-100/330,DZ10-160/330,DZ10-250/330,DZ10-400/330 Frame current 250 (A) Rated current 250A Rated working voltage 100A Release rated current 100A Rated insulation voltage 380V Rated operating short-circuit segmentation capacity Ics 3kA (KA) Rated ultimate short-circuit breaking capacity Icu 5kA (KA)
Suitable for distribution networks with AC frequency of 50Hz, voltage up to AC400V, and current up to 600A, used for distributing electrical energy, overload and under voltage, and short circuit protection of power lines and equipment, as well as for infrequent disconnection and connection of power lines under normal working conditions.
This product complies with GB14048. 2 standard.
The insulation base and cover are pressed with Thermoplastic. The operating mechanism is a four link type. The release is divided into multiple type (equipped with overload protection and short circuit protection), electromagnetic type (equipped with short circuit protection), and thermal release type (equipped with overload protection). There are two types of wiring methods: front and back.
