Specifications
Product Description
The Diferencial Tipo B 4P 25A 30mA Tongou TORD4B-63 is a four-pole residual current circuit breaker (RCCB) for personal protection and fire prevention in demanding three-phase installations. Its class B rating ensures reliable operation against residual currents of any waveform: sinusoidal (AC), pulsating (type A), and smooth direct current, which is essential when using power electronics such as electric vehicle chargers, photovoltaic inverters on the grid side, frequency converters, or rectified power supplies. With a rated current of 25 A, sensitivity of 30 mA, and voltage of 380–415 V at 50 Hz, it provides real safety in residential, tertiary, and light industrial panels.
Main Features
- Class B according to IEC/EN 62423: detects AC, pulsating DC, and pure DC.
- 4P configuration, 25 A, 30 mA; three-phase voltage 380–415 V, 50 Hz.
- Conditional short-circuit capacity: 6 kA; Ui 250 V; Uimp 6 kV.
- IP40 (modular device) and IP20 (terminals) ratings for standardized panels.
- Wide terminals: rigid cable 1–25 mm² and with ferrule/flexible 1–16 mm²; tightening torque 2 Nm.
- Durability: 20,000 mechanical operations and 15,000 electrical; permissible altitude 2000 m.
Advantages or Benefits
- Complete three-phase safety even with harmonics and DC components that saturate AC or A type RCCBs.
- Service continuity thanks to an immune and stable architecture, reducing nuisance tripping.
- Clean installation: modular 8-step format (≈71.6 mm), 35 mm DIN rail, and clear status indication.
- Regulatory compliance EN/IEC 61008-1 and IEC/EN 62423, suitable for audits and occupational risk prevention.
- Wiring flexibility with common cross-sections in EV subpanels, pumps, and HVAC.
Purpose or Applications
Ideal for domestic or parking three-phase charging points, photovoltaic self-consumption with AC connection, speed drives in pumps/ventilation, and building service lines. It is the recommended choice when the equipment manufacturer requires a type B RCCB or there is a risk of residual DC injection.
