GMC-50接触器是用来远距离频繁地接通和断开交直流主电路和大容量控制电流的电器。具有动作迅速控制容量大使用安全方便，能频繁操作和远距离操作等优点。主要用作电动机的主控开关；小型发电机；电热设备；电焊机和电容器组等各种设备的主控开关。能接通和断开负载电流，但不能切断短路电流，因此常与熔断器和热继电器等配合使用。主要由触头系统；电磁机构和灭弧装置等组成。线圈和静触头是固定不动的，当线圈通电后，产生的电磁力克服弹簧的反作用力，将衔铁吸合并使动；静触头接触，从而接通主电路。当线圈断电时，由于电磁吸力消失，衔铁依靠弹簧的反作用力而跳开，动触头和静触头也随之分离，切断主电路。按电流分：交流接触器和直流接触器。按主触头分：单极；双极和三极等。按操作机构分：电磁式；气动式和液压式。“高品质低价格GMC-91a1bGMC-12/4★★★高品质低价格GMC-12×（2）92a2bGMC-100L2a2b原装正品高品质低价格GMC-121a1bGMC-18/4★高品质低价格GMC-18×（2）92a2bGMC-125L2a2b原装正品高品质低价格GMC-181a1bGMC-22/4★高品质低价格GMC-22×（2）92a2bGMC-150L2a2b原装正品高品质低价格GMC-221a1bGMC-32/4★高品质低价格GMC-32×（2）92a2bGMC-180L2a2b原装正品高品质低价格GMC-321a1bGMC-40/4★高品质低价格GMC-40×（2）92a2bGMC-220L2a2b原装正品高品质低价格GMC-401a1bGMC-50/4★高品质低价格GMC-50×（2）92a2bGMC-300L2a2b原装正品高品质低价格GMC-501a1bGMC-65/4★高品质低价格GMC-65×（2）92a2bGMC-400L2a2b原装正品高品质低价格GMC-651a1bGMC-75/4★高品质低价格GMC-75×（2）92a2bGMC-6M1a或1b原装正品高品质低价格GMC-751a1bGMC-85/4★高品质低价格GMC-85×（2）92a2bGMC-9M1a或1b原装正品高品质低价格GMC-851a1bGMC-100/42a2b★高品质低价格GMC-100×（2）1004a4bGMC-12M1a或1b原装正品高品质低价格GMC-1002a2bGMC-125/42a2b★高品质低价格GMC-125×（2）1004a4bGMC-16M1a或1b原装正品高品质低价格GMC-1252a2bGMC-150/42a2b★高品质低价格GMC-150×（2）1004a4bGMD-6M1a或1b原装正品高品质低价格GMC-1502a2bGMC-180/42a2b★高品质低价格GMC-180×（2）1804a4bGMD-9M1a或1b原装正品高品质低价格GMC-1802a2bGMC-220/42a2b★高品质低价格GMC-220×（2）1804a4bGMD-12M1a或1b原装正品高品质低价格GMC-2202a2bGMC-300/42a2b★高品质低价格GMC-300×（2）1804a4bGMD-16M1a或1b原装正品高品质低价格GMC-3002a2bGMC-400/42a2b★高品质低价格GMC-400×（2）1804a4bGMC-6MR1a或1b原装正品高品质低价格GMC-4002a2bGMC-600/42a2b★高品质低价格GMD-9×（2）92a2bGMC-9MR1a或1b原装正品高品质低价格GMC-6002a2bGMC-800/42a2b★高品质低价格GMD-12×（2）92a2bGMC-12MR1a或1b原装正品高品质低价格GMC-8002a2bGMD-9/4★高品质低价格GMD-18×（2）92a2bGMC-16MR1a或1b原装正品高品质低价格GMD-91a1bGMD-12/4★高品质低价格GMD-22×（2）92a2bGMD-6MR1a或1b原装正品高品质低价格GMD-121a1bGMD-18/4★高品质低价格GMD-32×（2）92a2bGMD-9MR1a或1b原装正品高品质低价格GMD-181a1bGMD-22/4★高品质低价格GMD-40×（2）92a2bGMD-12MR1a或1b原装正品高品质低价格GMD-221a1bGMD-32/4★高品质低价格GMD-50×（2）92a2bGMD-16MR1a或1b原装正品高品质低价格GMD-321a1bGMD-40/4★高品质低价格GMD-65×（2）92a2b原装正品-高品质低价格GMD-401a1bGMD-50/4★高品质低价格GMD-75×（2）92a2b原装正品以服务赢市场、以品质赢关注、以诚信赢客户”。努力为客户创造价值。为制造商创造市场、为代理商经销商创造利润。我们会做到诚信经营.以高质量的产品.优质的服务面向广大客户.欢迎广大客户前来定购/)
