Type B Residual Current Circuit Breaker 4P 32A 30mA Tongou TORD4B-63
Modelo: TORD4B-63 Tipo B 4P 32A 30mA- Sku: TONGPRO008
- Vendor: Tongou
Specifications
Product Description
The Type B RCCB 4P 32A 30mA Tongou TORD4B-63 is designed for three-phase panels with electric vehicle chargers, AC photovoltaic inverters, and variable speed drives. The B class ensures detection of residual leakage AC, pulsating DC, and pure DC, preventing core saturation that renders type AC or A RCCBs inoperative. Its rated current of 32 A and sensitivity of 30 mA provide a perfect balance between line capacity and personal protection, facilitating regulatory compliance in residential and tertiary environments.
Main Features
- Type B RCCB compliant with IEC/EN 62423; 4 poles, 32 A, 30 mA.
- Three-phase voltage 380–415 V, frequency 50 Hz.
- Conditional short-circuit capacity: 6 kA; Ui 250 V; Uimp 6 kV.
- Protection degrees: IP40 (modular) and IP20 (terminals); DIN rail 35 mm mounting.
- Large section terminals: rigid 1–35 mm² and with ferrule/flexible 1–25 mm²; tightening torque 2.5 Nm.
- Durability: 20,000 mechanical operations and 15,000 electrical; permissible altitude 2000 m.
Advantages or Benefits
- Total three-phase safety against any form of residual leakage in systems with power electronics.
- Greater line capacity (32 A) for charging points, subpanels, and medium-power three-phase equipment.
- Optimized installation: width 8 modules (≈71.6 mm), compact dimensions, and versatile wiring.
- Reliability and compliance with EN/IEC 61008-1 and IEC/EN 62423 for professional projects and audits.
- Fewer false trips thanks to its design immune to harmonics and noise typical of drives and inverters.
Purpose or Applications
Recommended for garages and parking lots with three-phase wallbox, AC-connected self-consumption installations, HVAC, pumps, and any process with drives. It is the indicated option when the manufacturer explicitly requires a type B RCCB or the presence of a DC component is expected.
