Type B Residual Current Circuit Breaker 4P 63A 30mA Tongou TORD4B-63
Modelo: TORD4B-63 Tipo B 4P 63A 30mA- Sku: TONGPRO010
- Vendor: Tongou
Specifications
Product Description
The Diferencial Tipo B 4P 63A 30mA Tongou TORD4B-63 is the highest capacity option for three-phase lines supplying powerful electric vehicle chargers, AC photovoltaic inverters, or variable frequency drives. Class B ensures detection of AC, pulsating DC, and pure DC leakage, an essential requirement when there is power electronics that may inject a DC component. With a nominal 63 A and 30 mA sensitivity, it protects people and provides reliability in advanced residential panels, parking lots, and small industrial installations.
Main Features
- Type B RCCB (IEC/EN 62423), 4 poles, 63 A, 30 mA.
- Operating voltage 380–415 V AC, 50 Hz; 35 mm DIN rail mounting.
- Conditional capacity: 6 kA; Ui 250 V; Uimp 6 kV.
- IP40/20 ratings, width 8 modules (≈71.6 mm), compact dimensions.
- Terminals: rigid 1–35 mm² and with ferrule/flexible 1–25 mm²; torque 2.5 Nm.
- Durability: 20,000 mechanical operations and 15,000 electrical; altitude up to 2000 m.
Advantages or Benefits
- Maximum safety in subpanels for charging and connections requiring 63 A.
- Reduction of unwanted tripping and immunity to harmonics/noise.
- Modular format that optimizes space and simplifies maintenance.
- Full compliance with EN/IEC 61008-1 and IEC/EN 62423.
- Versatile wiring with large cross-sections and recommended use of ferrules.
Purpose or Applications
Ideal for high-power three-phase wallboxes, AC self-consumption/backup, HVAC, and pumping with variable frequency drives. Recommended when the manufacturer requires a class B RCCB or there is a risk of residual DC injection.
