MOULDED CASE CIRCUIT BREAKER

New Products / New Technology

SDM6 series plastic housing circuit breakers are a new type of product designed and developed by our company using interational advancedtechnology and obtaining multiple patents. They are characterized by compact size, modularizaion, high breaking, double break points. zerolashover, and green environmental proteclion, t is suitable for distibuion networks with AC 50Hz, 60Hz, raled working voltage 690V and belowand rated curent 12.5A to 1600A. lt is used to distribute electric energy and protect lines and power equipment from overoad, short circuitundervotage, and other faults. lt can also be used for infrequent switching of lines and infrequent starting of motors under normal condiions.The SDM6 series circuit breaker is also equipped with an inteligent controler, which not only increases the seleclion range of seling curentbut also has LCD display, overload setting curent, short circuit delay current,short circuit instantaneous current, and tripping time that can beset, as well as short circuit instantaneous three-stageDrotactnprotection:Equipped with RS485 communication interfaceanoNdaNoameand MODBUS-RTU protocol:, DL645 protocol, users can choose according to their needs, Remole siqnaling: breakingl/closing, tripping, alarm.and fault status indication; Remote control: breaking, closing, reseting; Telemetny: three-phase curent and N-phase curent, grounding currenttrip memory function, and functions such as querying trip recording parameters, further improving the rellablty a

SDM6LR SERIES RESIDUAL CURRENT PROTECTION CIRCUIT BREAKER

New Products / New Technology

The SDM6LR series residual curent protection circuit breaker (hereinafter referred to as the cicuit breaker)is mainly suitable for distibutionnetworks with AC 50Hz and rated working voltage AC400V.Used for power supply and consumption systems with three-phase four wire neutralpoint direct grounding,it has functions such as overload,short circuit,phase loss,overvoltage,undervoltage,residual curent action protection,etc.It can protect circuits and equipment from damage,and also provide protection against possible grounding faults and human body contact inthe circuit.The product complies with the GB/T14048.2 standard.

MOTOR PROECTON CIRCUIT BREAKE

New Products / New Technology

The SDM7 Series Motor Protection Circuit Breaker(also known as Motor Protector or Motor Starter,hereinafter referred to as "the circuit breaker")is designed for circuits with AC voltages up to 690V andrated currents up to 80A.
This integrated device combines the functions of an isolation switchcircuit breaker,and thermal relay ina single unit.Key features include isolation protection,overload protection,temperature compensation,phase failure protection and short-circuit protection.
And the applications include direct starting and control of three-phase squirrel-cage asynchronous motors,distribution line protection and infrequent load switching.
The SDM7 circuit breaker complies with the standards of GB/T 14048.2,GB/T 14048.4,IEC60947-2,andIEC 60947-4-1.
