- Vendor: Tongou
Specifications
Product Description
The Tongou TORD4B-63 Type B RCCB 2P 25A 30mA is designed for single-phase 230–240 V networks that include electric vehicle chargers, AC-connected photovoltaic inverters, and variable speed drives. As a Type B device, it detects sinusoidal, pulsating, and direct residual currents, providing the highest level of personal and fire protection when power electronics are present. Its modular DIN rail construction, robust electrical characteristics (6 kA conditional, Ui 250 V, Uimp 6 kV), and mechanical/electrical durability make it the professional choice for residential and commercial distribution boards.
Main Features
- Universal leakage protection: AC, A (pulsating DC), and smooth DC in accordance with IEC/EN 62423.
- 2P configuration, rated current 25 A and sensitivity 30 mA; voltage 230–240 V, 50 Hz.
- Conditional short-circuit capacity: 6 kA; Ui 250 V and Uimp 6 kV.
- IP40/IP20 ratings, status indication, and toggle actuator.
- Service life: 20,000 mechanical operations and 15,000 electrical; tightening torque 2 Nm.
- Operating range: −25 °C to +60 °C; installation height up to 2000 m.
Advantages or Benefits
- Complies with EV manufacturer requirements and applicable regulations for the presence of residual DC.
- Clean and quick installation on DIN rail, with terminals prepared for rigid cable or with ferrule.
- Enhanced safety in environments with converters, preventing nuisance tripping and improving service continuity.
- Compact format that optimizes electrical panel space.
Purpose or Applications
Ideal for domestic and professional charging points, solar self-consumption with AC injection/disconnection, HVAC, pumps, and processes with variable speed drives. Recommended when class B is required by equipment specification or due to the presence of harmonics and direct current components.
