2CSF204196R4630 ABB F204 A-63/0.5 16-2/3Hz RCCB 4P Type A 500mA 63A

Why Choose the ABB F204 A-63/0.5 16-2/3Hz RCCB?

The ABB F204 A-63/0.5 16-2/3Hz, order code 2CSF204196R4630, is a specialised 4-pole Type A residual current circuit breaker (RCCB) designed for electrical systems operating at 16-2/3 Hz. Part of the established ABB F200 / FH200 RCCB product group, it combines a 63 A rated current with 500 mA residual current sensitivity.

Its Type A residual current characteristic provides detection of sinusoidal AC residual currents and pulsating DC residual currents. This gives the device broader residual current detection capability than a Type AC RCCB and makes it suitable for appropriately designed circuits containing electrical or electronic equipment capable of producing pulsating DC residual currents.

The distinctive feature of this F204 variant is its 16-2/3 Hz operating frequency, making it a purpose-specific RCCB rather than a conventional 50/60 Hz device. Its 4-pole configuration supports multi-pole electrical distribution applications requiring residual current protection at this specialised supply frequency.

Key Advantages

• Specialised 16-2/3 Hz RCCB for compatible low-frequency electrical systems.
• 63 A rated current for appropriately rated distribution circuits.

Specialised 16-2/3 Hz Type A Residual Current Protection

The ABB F204 A-63/0.5 16-2/3Hz is specifically identified for operation at 16-2/3 Hz. This frequency characteristic is particularly important when selecting residual current protection because RCCBs must be suitable for the electrical characteristics of the system in which they are installed. A conventional 50/60 Hz RCCB should not be assumed to provide equivalent performance in a specialised 16-2/3 Hz application.

As a Type A RCCB, this device responds to sinusoidal AC and pulsating DC residual currents. It is an RCCB rather than an overcurrent protective device and therefore does not by itself provide overload or short-circuit protection. Appropriate overcurrent protection must be selected separately according to the electrical system design and applicable installation requirements.

Typical Applications

• Specialised electrical systems operating at 16-2/3 Hz.
• Low-frequency electrical distribution installations.
• Four-pole circuits requiring Type A residual current protection.
• Special-purpose industrial electrical systems.
• Infrastructure installations using compatible low-frequency supplies.
• Circuits requiring detection of sinusoidal AC and pulsating DC residual currents.
• Installations requiring 63 A, 500 mA residual current protection at 16-2/3 Hz.
