STID-B RCCB B model is worked on type A and in additon for smooth DC residual currents, residual DC currents that may result fromrectifying circuits and high frequency AC residual currents.Itprotects in the event ofcontunuous fault current on three phase networks.Itusually is used in the field of Recharging Station,MedicalApparatus and Instruments, Controllers and Variable Speed Drives, Batter Chargesand Inverters(DC)..STID-B complys with IEC/EN61008 and IEC/EN62423 standard.
General
1. Application:For protecting cables and equipments against
overload and short circuit.
2. General rules for choosing RCCB.
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 curve (3-5In) protection and control of the circuits against
length cables in TN and IT systems.
C curve (5-10In) protection and control of the circuits against
overloads and short-circuits; protection for resistive and
inductive loads with low inrush current.
D curve (10-14In) 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,breakdown lamps.)
