tw30适用于交流50/60hz,额定电压690v及以下，额定电流200~6300a的供电系统中，2000a壳体icu=ics=80ka icw=65ka 1s, 3200a壳体icu=100ka icw=65ka 1s, 6300a壳体icu=120ka icw=85ka 1s。
采用智能脱扣器，具有过载保护、短路短延时保护、短路瞬时保护、接地保护，可以方便地调整各种保护参数，能与多种工业现场总线连接，实现远程监控。
tw30 series circuit breaker is suitable for the power supply system of ac 50-60hz, rated voltage 690v and below, rated current 200~6300a. breaker of frame current 2000a meets the standard of icu=ics=80ka and icw=65ka 1s. frame current 3200a reaches icu=100ka and icw=65ka 1s, and frame current 3200a reaches icu=120ka and icw=85ka 1s.
using intelligent release, with overload protection, short circuit protection short delay, instantaneous short-circuit protection, earthing protection,tw30 can easily adjust the protection parameters, with a variety of industrial field bus connection, and the realization of remote monitoring.
