Description

GDM3L series residual current operated circuit breaker (abbreviated as residual circuit breaker) is a patented product developed by our company in recent years. It is an integrated, multifunctional, overcurrent and overcurrent adjustable residual circuit breaker. It is suitable for three-phase four-wire neutral  low-voltage power grid direct-grounding (TT grounding system) is used as residual protection and can also protect the ground fault,overcurrent,short circuit of the line or electrical equipment
Characteristic
1.Multiple functions The general type has protection functions for residual current,phase default overvoltage,undervoltage, overcurrent and short circuit. There are also practical functions such as automatic reclosing,constant cycle voltage,current,residual current display,operating status indication etc.
2.Strong anti-interference ability This residual circuit breaker adopts advanced and lightning protection technology in hardware and software programs which has better lightning protection effect than similar products: and can resist various peak interferences, stable and reliable operation
3.High breaking This residual circuit breaker is designed with the structure of GDM1 plastic case circuit breaker, which has the characteristics of compact structure and strong breaking capacity
4. Record available  check When the device is operated, digital turns display real-time load current, voltage and residual current of each phase; display (lock) action current value when tripping and display the reason of tripping with indicator light. Provide convenience for finding faults. You can also check historical trip causes and times
5.Intelligent The intelligent control circuit composed of a single-chip microprocessor with high accuracy and precision; the overcurrent protection is electronically settable, and the overcurrent setting value can be adjusted according to the actual site
6.Communicable The communicable product is connected with the GPR5 communication module, and can send a message of the trip status to the manager's mobile phone.
