NewTrend / OEM · RD9L
Product overview
NewTrend RD9L operating modules combine with YL9M RCCBs or GYR9NM RCBOs. Choose automatic reclosing, RS485 remote operation or Wi-Fi app control, then select the matched breaker and its protection settings.
Technical selection summary
| Breaker selection | YL9M RCCB: 2P/4P, 25/40/63A, Type AC or A, 30/100/300mA. GYR9NM RCBO: 1P+N/3P+N, 25/32/40A, B/C/D, Type AC or A, 30/100/300mA |
|---|---|
| Protection difference | RCCB provides residual-current protection only and needs coordinated overcurrent protection. RCBO also provides overload/short-circuit protection. A trip curve is not applicable to the RCCB |
| Module supply | R and S: separate AC220V or DC12V versions. W: AC220V only. The module control supply is independent of the main circuit voltage |
| R automatic version | Three attempts at 10s, 60s and 300s; after successful closing without another trip for 15 minutes, the counter resets. AUX COM/NC maximum 100mA. Do not interpret reclosing as fault clearance |
| S RS485 version | MODBUS-RTU remote opening/closing and status. The R version’s automatic retry sequence is not attributed to S |
| W Wi-Fi version | 2.4GHz 802.11 b/g/n; Tuya app opening/closing and scheduled switching. AUTO enables app control; MANU enables local operation. No 5GHz or independent R-type retry sequence is claimed |
| Published short-circuit scope | 6kA documented assembly version. For YL9 this is conditional Inc/IΔc with coordinated upstream protection; it is not standalone overcurrent interruption. The RCCB catalogue also lists a 10kA variant, which is not offered without exact version evidence |
| Dimensions / wiring | Module 82×18×78mm; illustrated assembly widths 53mm or 88mm. Retain exact component outlines and separate R/S/W wiring; accessory and enclosure clearances must be checked |
| Operating limits | Module IP20; −20 to +55°C; supply ±10%; action ≤1s. Mechanical life 10,000 operations in supplier module catalogue |
| Supply identity | NewTrend supply and RD9L naming retained. GEYA GRD9L reference documents are used with owner authorization; component names follow supplied NewTrend YL9 and GYR9N catalogues |
Specify the breaker assembly, poles, current, residual-current type/sensitivity, trip curve when applicable, control mode, separate module supply and quantity. This published selection uses instantaneous electromagnetic components; delayed/SI, electronic and 10kA RCCB variants need their exact configuration.
Typical applications
- Remote distribution panels requiring controlled switching
- Meter boxes and auxiliary distribution with matched residual-current protection
