Scope:KB0 is intended to be connected to circuits of rated voltage not exceeding690V, and rated current from 0.16A to 100A, 50Hz (60Hz), available for making,carrying and breaking currents under normal conditions including specifiedoperating overload conditions, and also available for making, carrying for aspecified time and breaking currents under specified abnormal conditions(such as short-circuit current).Functions:KB0 is of modular design, associated and coordinated with the functions oftraditional circuit breaker, fuse, contactor, over-load relay, starter, anddisconnecter, intended to provide both protective and control functions forremotely or local manually controlled circuits, having front indications, signalalarm and time-current characteristics, and also available for control andprotection of motors and distribution circuits by using optional modules oraccessories.Applications:With its advantages of integration, module, compact size, high protectiondegree, high breaking capacity, short ionization distance, longer life, continuityof service, high reliability and easy installation and maintenance, KB0 is suitablefor control and protection of motors to be used in the field of metallurgy industry,coal mime industry, iron and steel industry, petrochemical industry, harbors,railway stations, etc., and for control and protection of lighting, power transferring,pumps, ventilators and air conditioners in modern buildings, as well as forcontrolling and protecting of distribution system, motor control center (MCC), andfactories or workshops.Main technical data:1) Two outline dimensions (C and D frame size): 3-pole and 4-pole2) Current ratings: 12, 16, 18, 32, 45, 63 and 100A3) Min. setting current: 0.16A4) Max. setting current: 100A5) Short-circuit break capacity:a) 35kA for type C (economic)b) 50kA for type Y (standard)c) 80kA for type H (high capacity)6) Opening time under prospective short-circuit current is 2 ~ 3ms, atcurrent limiting of 0.2 and below7) Types of over current releases:a) Classification according to working principle: thermal-magnet release,electronic controller, intelligent controllerb) Classification according to protections: motor protection, distributionprotectionc) Classification according to operating frequency: frequent operation,infrequent operation. The outline dimensions of C and D frames forthermal-magnet release, intelligent controller and electronic controllerare as same as their dimensions of installation
