ABB F202B-1603 Type B Residual Current Circuit Breaker, 2-Pole, 16 A, 30 mA, 230/400 V AC 2CSF202568R1160

The ABB F202B-1603 stands apart from standard residual current devices by offering Type B protection, which detects AC, pulsating DC, and smooth DC residual currents. This capability is essential for circuits with three-phase rectifiers, frequency converters, EV charging stations, and other equipment that can generate DC fault currents. With a 16 A rated current and 30 mA sensitivity, it provides both personal protection and fire prevention in a compact 2-module DIN rail housing.

Highlights

• Type B residual current protection for AC, pulsating DC, and smooth DC faults
• 2-pole design, 16 A rated current, 30 mA rated residual operating current
• Rated voltage 230/400 V AC, suitable for 50/60 Hz systems
• 10 kA rated conditional short-circuit current (Inc) and residual short-circuit current (IΔc)
• Instantaneous tripping characteristic for rapid disconnection
• DIN rail mounting with screw terminals accepting up to 35 mm² rigid conductors
• IP20 protection (terminals), IP40 when installed in an enclosure
• Complies with IEC/EN 61008-1

In daily use

Installation is straightforward on a standard 35 mm DIN rail. The screw terminals provide secure connections for conductors up to 35 mm² rigid or 25 mm² flexible, ensuring reliable performance in distribution boards. The device operates within a temperature range of -25 °C to +55 °C, making it suitable for a wide range of environments. With an electrical endurance of 10,000 cycles and mechanical endurance of 20,000 cycles, it offers long-term reliability. The instantaneous tripping ensures that any residual current above 30 mA is interrupted without delay, protecting both people and equipment.
