Specifications
High breaking miniature automatic miniature circuit breaker application YCBKN has advanced structure, reliable performance, high breaking capability and pleasing outlook and small size. The case and the partsare adopted by high fire-resistant and shockproof plastics. It is suitable for using in the circuit with 50HZ/60HZ, rated working voltage 400V and below, rated current up to 63A for protecting the illuminating, distributing line and of office, house and building from overload, short circuit. It also can be used for infrequently switching line under the normal condition. The product comply with standards IEC60989 and GB10963.
General
1. Application: For protecting cables and equipments against overload and short circuit.
2. General rules for choosing MCB.
A. Technical data of the network at the point considered:
The earthing systems, short-circuit current at the circuit breaker installation point,
Which must always be less than the breaking capacity of this device, network normal voltage.
B. There are 3 curve characteristics for magnetic operation:
B curve(3-5 In) protection and control of the circuits against length cables in TN and IT systems.
C curve(5-10 In) protection and control of the circuits against overloads and short-circuits; Protection for resistive and inductive loads with low inrush current.
D curve(10-20 In)protection and control of the circuits against overloads and short-circuits; Protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers, breakdowm lamps).
