TM1Z塑料外壳式直流断路器

TM1Z DC Moulded Case Circuit Breaker

TM1Z系列塑料外壳式直流断路器(以下简称断 路器),是本公司采用国际先进设计' 制造技术硏 制、开发的新型断路器之一其额定绝缘电压为 1000V,适用于额定工作电压至DC1000V及以下,额 定工作电流至800A及以下的直流电网电路中,用来 分配电能和保护线路及电源设备免受过载、短路等故 障的危害。

TM1Z series DC moulded case circuit breaker (hereafter referred io as breakers) are one of the new type breakers which have been developed by the company using international advanced design and manufacturing technology. The rated insulation voltage of the breakers is 1000V, suitable for the DC grid witti rated working voltage up to 1000V, and rated working current up to 800A DC power grid. The breakers have overload, short-circuit and under voltage protection devices, so as to protect the circuit and the power equipment against damage.
