AL21 Miniature Circuit Breaker
Miniature Circuit Breaker Application:
AL21 miniature circuit breaker is mainly suitable for overload and shortcircuit protection, it is especially used for illumination and distribution inindustry and commerce. It is of pleasing outlook&highbreaking capacity etc. Its frame and parts adoptsplastics of light weight, reliable performance, high inflammable resistance andshock resistance for long service life. It is mainly used for overload andshort circuit protection within the circuit of AC 50/60Hz, rated voltage ofsingle pole up to 240V, two, three or four pole up to 415V. It can alsobe used for an unfrequentswitchover of the circuit and illumination under normal conditons.
