Square D

For use with Qwikline I consumer units and can be retrofitted in to existing systems,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
