Scope of Application

TXD7-63 Residual Current Circuit Breakers are new earth leakage Circuit Breakers which have been innovated, researched and developed by the company using rich production experience and international cutting-edge technology. The earth leakage Circuit Breakers have protection function of overload, short circuit, residual leakage current action, current limiting and other functions, and with international high-tech products. Products with high operating performance are suitable for the line with AC 50/60Hz, rated voltage of single-pole and two-wire, two poles for, 230V, three poles, four poles for 400V and rated current of 63A. When the leakage current from the circuit equipment or grid exceeds the specified value, residual current operated circuit breaker can cut off trouble power quickly in a very short time to protect personal and electrical equipment. The earth leakage circuit breaker can protect overload and short-circuit of the circuit or motor, it can also be converted and started infrequently under normal circumstances. The earth leakage circuit breakers meet the standards of GB16917.1-2003 and IEC61009-1, the product obtains design the national patent certificate.
