Type B Residual Current Device 4P 40A 30mA Tongou TORD4B-63
Modelo: TORD4B-63 Tipo B 4P 40A 30mA- Sku: TONGPRO009
- Vendor: Tongou
Specifications
Product Description
The Diferencial Tipo B 4P 40A 30mA Tongou TORD4B-63 is a four-pole RCCB for three-phase installations with power electronics, such as electric vehicle chargers, photovoltaic inverters on the grid side, or variable frequency drives. Class B ensures operation against residual sinusoidal (AC), pulsating (type A), and pure direct current leaks, preventing the saturation that renders conventional RCCBs ineffective. With a nominal 40 A and 30 mA sensitivity, it ensures personal protection and reduces fire risk in residential, tertiary, and light industrial panels.
Main Features
- True Class B according to IEC/EN 62423: detection of AC, A, and smooth DC.
- 4P, 40 A, 30 mA, 380–415 V, 50 Hz; modular format for 35 mm DIN rail.
- Conditional short-circuit capacity: 6 kA; Ui 250 V; Uimp 6 kV.
- IP40 (device) / IP20 (terminals) ratings; width 8 modules (≈71.6 mm).
- Terminals: rigid 1–35 mm² and with ferrule/flexible 1–25 mm²; tightening torque 2.5 Nm.
- Durability: 20,000 mechanical and 15,000 electrical operations; max altitude 2000 m.
Advantages or Benefits
- Complete three-phase safety in the presence of harmonics and DC component.
- Service continuity with lower tendency to unwanted tripping.
- Compact and tidy installation: 8 steps, clear signaling, and wide terminals.
- Complies with EN/IEC 61008-1 and IEC/EN 62423 for professional projects.
- Simple maintenance with front access and ferrule recommendation.
Purpose or Applications
Recommended for three-phase wallbox units, EV subpanels, AC self-consumption, HVAC, and pumping with variable frequency drives. Optimal when the manufacturer requires class B or there is a risk of residual DC injection.
