This product is an ideal solution for circuit breaker manufacturers, as it integrates a power supply for easy operation. Customers do not need to modify circuit structures and can directly mount the product onto existing circuit breakers.
Advantages
1. Type B Residual Current Detection, Compliant with Industry Standards.
With the increasing number of electrical devices, fault residual current waveforms have become more complex and diverse. Conventional AC/A residual current detection is prone to failure in such scenarios. Some low-voltage electrical industry standards mandate the use of Type B residual current detection. The TTLBxx-D3 series fully complies with IEC62423 and GBT 22794 standards and is capable of detecting AC, pulsating DC, high-frequency AC, and DC residual currents, among others.
2. Easy to Use: Features an integrated power supply and mounts directly onto circuit breakers.
This product series comes with an integrated power supply module that can be directly connected to a 220V (single-phase) or 380V (three-phase) mains power supply without any additional conversion processing.
It utilizes a side-mount connection method between the power supply board and the residual current detection module, resulting in a smaller footprint that can be directly embedded in the circuit breaker. This design reduces customer design time and space limitations, improving space utilization.
3. High Immunity to External Interference:
The product demonstrates strong anti-interference capabilities during EMC testing (CE, RE, EFT, and overvoltage, etc.), ensuring compliance with standards without rejection or malfunction.
EFT compliance: 4kV, Tr/Th: 5/50ns, repetition rate: 5kHz.
Overvoltage compliance: Tr/Th: 1.2/50us, line-to-line: 4kV/2Ω.
Applications:
The TLBxx-D3 series is suitable for low-voltage electrical applications, providing safe and reliable circuit breaker protection in applications such as city lighting, smart homes, smart grids, etc.
