KB0 is intended to be connected to circuits of rated voltage not exceeding 690V,
and rated current from 0.16A to 100A, 50Hz (60Hz) AC, available for making, carrying
and breaking currents under normal conditions including specified operating
overload conditions, and also available for making, carrying for a specified time
and breaking currents under specified abnormal conditions (such as short-circuit
current).
KB0 is of modular design, associated and coordinated with the functions of traditional
circuit breaker, fuse, contactor, over-load relay, starter, and disconnector,
intended to provide both protective and control functions for remotely or local
manually controlled circuits, having front indications, signal alarm and time-current
characteristics, and also available for control and protection of motors
and distribution circuits by using optional modules or accessories.
KB0 is designed to be operated either by automatic control or by manual control,
able to have functions of remote control and direct manual control. KB0 can be
installed in a predetermined cabinet to be formed as a power terminal box, which
is available for distribution protection and control of the outside and remote independent
load.
