Type B characteristic offers instantaneous short circuit response level of 3-5 x normal rated current, making it suitable for circuits with moderate inrush currents such as filament lamps, heating loads and most domestic/small building protection applications.,Type C characteristic offers short circuit response of 5-10 x normal rated current, making it ideal for circuits with higher inrush currents such as motor control and fluorescent lighting installations in industrial buildings where nuisance tripping might occur if a faster type was used. Type D characteristic is designed for high inrush loads. Magnetic trip point - 10 to 20 times In rating. Thermal trip point - 1.13
to 1.45 protector rating. Type AC characteristic ensure tripping for sinusoidal, alternating currents, whether they be quickly applied or slowly to increase.
