Additional Information
The TPNL Leakage Protective Circuit Breaker (RCBO) is a high-performance electrical safety device designed to provide comprehensive protection for single-phase residential, commercial, and light industrial electrical systems. By integrating overload protection, short-circuit protection, and earth leakage protection into a single compact unit, this RCBO helps prevent electrical accidents, equipment damage, fire hazards, and electric shocks.
Featuring a 30mA residual current sensitivity, dual-pole disconnection, and a 4kA short-circuit breaking capacity, the TPNL RCBO is an ideal choice for modern distribution boards where safety, reliability, and space efficiency are essential.

An RCBO (Residual Current Circuit Breaker with Overcurrent Protection) combines the functions of an MCB (Miniature Circuit Breaker) and an RCD/RCCB (Residual Current Device) into one device.
It protects against:
Unlike conventional circuit breakers, an RCBO continuously monitors current flow and disconnects the circuit immediately when abnormal leakage or overcurrent conditions are detected.
| TESTING CURRENT (A) | RATED VOLTAGE (V) | LIMITED TIME | PRE-ENGAGE RESULT | START SITUATION | NOTE |
|---|---|---|---|---|---|
| 1.13In | all | t≥1h | non-trip | cold state | The current rises steadily to a fixed value within 5s |
| 1.45In | all | t<1h | trip | heat state | Open the supplementary switch, connect the power |
| 2.55In | all | 1s < t < 60s | trip | cold state | Open the supplementary switch, connect the power |
| 5In | all | t≥0.1s | non-trip | cold state | Open the supplementary switch, connect the power |
| 10In | all | t<0.1s | trip | cold state | Open the supplementary switch, connect the power |
The TPNL RCBO continuously compares the current flowing through the live conductor with the current returning through the neutral conductor.
Under normal conditions:
Current entering = Current leaving
If leakage occurs due to:
the current balance is disturbed.
When the leakage exceeds 30mA, the breaker instantly disconnects the circuit to protect users and equipment.
Installation should always be performed by a qualified electrician according to local electrical regulations.
To ensure reliable operation:
Regular testing helps maintain effective leakage protection throughout the product's service life.
