Tianshui 213 Electrical Apparatus Co., Ltd. is a leading manufacturer of AC contactors, thermal overload relays, single pole DC contactors (for Telecom industry), contactor relay, miniature circuit breakers, molded case circuit breakers, air circuit breakers, and low voltage switchgear.

Since the establishing, we began to manufacture AC contactors. In 1984, in order to improve the quality of our AC contactors, we introduced AC contactor and thermal overload relay technology from Telemecanique. That is the reason why our AC contactors and relays are same as Schneider's. Now the quality of our AC contactors and relay are no.1 in China.
