SA-G3 Hydraulic magnetic MCB is mainly used to protect circuit against
overload and short-circuit. Adopting hydraulic magnetic trip instead of bimetal, it has a high sensitivity, and will not be affected by the
ambient temperature.

They are mainly used for illumination and distribution in industry or
domestic to protect circuit against overload and short-circuit. Under
the circuit of 50/60 Hz AC, 240V for one, two-pole; 415V for three-pole,
they are complying with IEC 157-1973, and BS3871.
