1. Product Overview
The TOMZN TPNL series Residual Current Circuit Breaker (RCBO) is designed for single-phase residential circuits operating at AC 50Hz/60Hz with a rated voltage of 220V. It provides essential protection against electron shock, overload, and short-circuit conditions. This product features a compact design, high breaking capacity, and ensures both live and neutral wires are cut off simultaneously for enhanced safety, even if the live wire is connected incorrectly.
This product conforms to international standards IEC61009, GB6829, and GB/16917.
Function Overview: When an overload or leakage occurs in the circuit, the equipment will automatically cut off the power supply to protect against electric shock and circuit damage.

5. Operating Instructions
- Operating Handle: The device features a widened, ergonomic T-shaped operating handle for easy manual operation (ON/OFF).
- Indicator Window:
- When the switch is in the "OFF" (down) position, the indicator window shows white, indicating that the circuit is disconnected.
- When the switch is in the "ON" (up) position, the indicator window shows red, meaning the circuit is closed.
- Test Button: A "test monthly" button is provided. Press this button once a month to ensure the leakage protection function is working correctly. This simulates a leakage and should trip the breaker.
