Application

AM3 series plastic housing circuit breaker (hereinafter referred to as circuit breaker), suitable for AC 50Hz(or 60Hz). Rated insulation voltage 690V(AM3-125, 500V). Rated operating voltage 660V(690V) and below. Dc 250V or below. In the circuit with rated current 12.5~1600A, it is used to distribute electric energy. Under normal conditions, it is used for infrequent closing and disconnecting, and in case of line and equipment overload. It is used to protect against short circuit and under voltage.

The main technical performance of AM3 series plastic shell circuit breaker has reached the international contemporary level. It has the features of compact structure, small size, high short-circuit breaking capacity, small flaring distance, modular installation of internal attachments, use of terminal protective cover to enhance safety, and "base", "cover" with different colors to enhance beauty and so on.

Circuit breakers comply with IEC60947-2, GB14048.2, GB 14048.4 and other standards.
