1. What is the GRD9L-S?
It is an intelligent automatic recloser and remote control mechanism equipped with an RS485 communication interface, designed to be physically coupled with and control Miniature Circuit Breakers (MCB), Residual Current Circuit Breakers (RCCB), or RCBOs.
2. What functions does it provide?
It provides remote monitoring and control of circuit breakers via RS485, automatic reclosing after a fault trip (up to 3 times to restore power automatically), and manual/automatic mode selection with double locking for safety.
3. What are the key parameters for selection?
The most critical parameters are the rated control supply voltage (DC12V, DC24V-48V, or AC220V) and ensuring you specify the exact matching MCB/RCCB/RCBO specification and model when ordering (e.g., GRD9L-S + GYM9 2P C40).
4. What are the currently available options?
You can select the control voltage type: D12 (DC12V) or A220 (AC220V). Additionally, it can be customized by combining it with accessories like Auxiliary contacts, Alarm contacts, Shunt releases, and Under-voltage releases.
5. What standards does it comply with and which market is it designed for?
It complies with CE certification standards and mounts on standard EN/IEC 60715 DIN rails. It is designed for global markets focusing on smart grid infrastructure, renewable energy (solar PV), EV charging, and smart home automation.
6. What are the installation precautions?
Installation must be performed by a qualified professional with the power supply completely disconnected. Ensure the module is securely attached to the matching breaker and properly seated on the DIN rail. Please read the product manual carefully before installation and operation.
