General
STET series high breaking capacity mini circuit breaker (MCB) protect electrical circuits against overload and shortcircuit current. They provide ON-OFF switching easily. MCB is applicable to electric circuits with rated voltage 230/400V AC, frequency 50/60Hz and rated current up to 60Amp. The product provides protection against overload and short circuit to electric circuits and equipments in household and commercial installations. MCB is also used as non-frequent changeover of electric circuits.
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.)
