2CSF202196R3630 ABB F202 A-63/0.3 16-2/3Hz RCCB 2P Type A 300 mA 63 A

Why Choose the ABB F202 A-63/0.3 16-2/3Hz RCCB?

The ABB F202 A-63/0.3 16-2/3Hz is a specialised 2-pole Type A residual current circuit breaker (RCCB) designed specifically for electrical systems operating at 16 2/3 Hz, a frequency used in railway applications. Identified by ABB order code 2CSF202196R3630, it forms part of ABB's F200 range of residual current protection devices.

Rated at 63 A with a rated residual operating current of 300 mA, the F202 A-63/0.3 16-2/3Hz provides protection against the effects of sinusoidal alternating and direct pulsating earth fault currents. Its Type A characteristic enables detection of both AC and pulsating DC residual-current waveforms.

Unlike standard-frequency RCCBs, this version is specifically designed to operate at a rated frequency of 16 2/3 Hz. Its dedicated railway application, 2-pole configuration and compliance with IEC/EN 61008 standards make it a purpose-designed residual current protection solution for compatible low-frequency railway electrical systems.

Key Advantages

• Specially designed for 16 2/3 Hz railway electrical systems.
• 63 A rated current for appropriately rated circuits.
• 300 mA residual operating current for earth-fault protection applications.
• Type A detection for sinusoidal alternating and direct pulsating residual currents.
• 2-pole configuration provides simultaneous switching of both live conductors.
• Part of ABB's established F200 RCCB range.

Purpose-Designed Protection for 16 2/3 Hz Railway Systems

Residual current protection must be matched to the electrical characteristics of the installation in which it operates. The ABB F202 A-63/0.3 16-2/3Hz is specifically engineered to work at a rated frequency of 16 2/3 Hz, making it suitable for railway applications using this low-frequency power system. It combines a 63 A current rating with a 300 mA residual current threshold.

Its Type A characteristic provides response to sinusoidal alternating and direct pulsating residual currents. The 300 mA sensitivity is not the 30 mA level used for additional protection against direct contact, so selection must reflect the required protective function and railway installation requirements. As an RCCB, it does not incorporate overload or short-circuit protection, which must be provided separately by appropriately coordinated protective devices.

Typical Applications

• Railway electrical installations operating at 16 2/3 Hz.
• Low-frequency railway power distribution systems.
• Railway circuits requiring 300 mA residual current protection.
• Single-phase railway auxiliary electrical systems.
• Circuits requiring Type A residual-current detection.
• Railway distribution assemblies requiring dedicated low-frequency RCCB protection.
