Application
| 3KB1 Series Miniature Circuit Breakers are suitable for protection against over load and short circuit in AC 230/400V,50(60)Hz circuits with rated current up to 1OOA, as well as for unfrequent switchover of circuits and motors under normal conditions. Technical features of 3KB1 Miniature Circuit Breakers:high short-circuit breaking capacity; excellent current-limiting properties; full enclosed terminals with high safety; power terminal connected with rigid bar or flexible wire, pleasing outward appearance; mounted with rails; low power loss and obvious energy-saving effect. They can be especially used in distribution system of modern buildings and in modular terminal apparatus combination units |
