Product Description
Application
NDB5 series circuit breaker for equipment (hydraulic-magnetic circuit breaker) is applied
in electrical system, of which the rated current is from 0.5A to 63A and the rated voltage is
AC230/400V, AC250V, AC480/277V (50/60Hz) or up to DC125V, to protect the circuit against the
overload current and short-circuit current. It is also can be used to make and break the circuit
infrequently. The product is widely used in computer and its peripheral equipment, industrial
automation devices, telecommunication equipment, power supply for telecommunication, UPS
equipment, railway-engine, marine electrical systems, aerospace electrical power system,
elevator control systems and mobile power equipment.
