High Breaking Miniature Circuit Breaker (DSC00060) - SB6-63 Series

SB6-63 series high breaking miniature circuit breaker

Service range: SB6-63high breaking capacity miniature circuit breaker is suitable for circuit of AC50HZ, rated voltage 400V and below, rated current up to 63A, applied to protect the circuit facility and electric equipments for buildings when there is overload or short circuit. In accords with IEC60898.
Structural characteristics: SB6-63 high breaking capacity miniature circuit breaker is made up of enclosure, operating mechanism, thermal release, electromagnetic release, contact system, arc extinguish system and so on, it presents overload and short circuit protection functions. The unique design structure and strong arc-extinguishing system make the product possess a short circuit capacity of 10KA (at present, the short circuit breaking capacity of miniature circuit breaker of 63A below is all 6KA). It has elegant appearance and is installed by rail.
Standard working condition: *Ambient air temperature shall be from +40ºC to -5ºC. If you use it under temperature condition higher than +40ºC or lower than -5ºC, please consult and negotiate with the manufacturer.
*Altitude for installation shall not exceed 2000M, if you use it in a higher altitude area, please consult and negotiate with the manufacturer.
*The air should be clean, and the relative humidity should not exceed 50% at the max temperature +40ºC. It allows higher relative humidity under lower temperature, for example, 90% for +20ºC. Notice, the temperature changing may cause condensation, please take proper measures at this moment.
*When the circuit breaker is vertically installed, the gradient to the vertical plane should not exceed 5ºC.
*Places where is no obvious shake, impact or vibration.
*If it is installed in a closed enclosure, and many pieces abut against each other, please use through capacitance-down, choose capacity-down ratio 0. 7-0. 8, you can choose higher value for metal enclosure, and choose lower value for full-plastic enclosure.
