Product Description

The Diferencial Tipo B 4P 16A 30mA Tongou TORD4B-63 is a four-pole RCCB for three-phase networks that incorporates residual leakage detection for any waveform. Its class B ensures operation in the presence of sine wave AC currents, pulsating DC, and smooth DC, providing the level of safety required by three-phase electric vehicle chargers, photovoltaic inverters on the AC side, frequency converters, pumps, and HVAC systems. With a rated current of 16 A and sensitivity of 30 mA, it is designed to protect people against indirect contact and reduce fire risk, while maintaining high immunity to harmonics and non-linear loads.

Main Features

Type B according to IEC/EN 62423: detection of AC, A (pulsating), and pure DC.
4 poles, 16 A, 30 mA; three-phase voltage 380–415 V, 50 Hz.
Conditional short-circuit capacity 6 kA; Ui 250 V; Uimp 6 kV.
IP40 (module) / IP20 (terminals) protection ratings. Mounting on 35 mm DIN rail.
Terminals: rigid 1–25 mm² and with ferrule/flexible 1–16 mm²; tightening torque 2 Nm (1–25 A).
Durability: 20,000 mechanical operations and 15,000 electrical; service altitude up to 2000 m.

Advantages or Benefits

Complete three-phase safety against any form of residual leakage, essential with power electronics.
Universal compatibility with three-phase EVs, grid-tied self-consumption inverters, and industrial frequency converters.
Compact installation: width of 8 modules of 9 mm (≈71.6 mm) and simple connection on DIN rail.
Reliability and compliance with EN/IEC 61008-1 and IEC/EN 62423 for audits and professional projects.
Simple maintenance thanks to accessible terminals and recommendation of ferrules for secure crimping.

Purpose or Applications

Perfect for three-phase panels in garages and parking lots, small industries, technical rooms in buildings, and pumping/HVAC systems with frequency converters. Recommended when the manufacturer explicitly requires class B or when the presence of residual DC that could saturate a conventional RCCB is detected.
