Why Choose the ABB F204 AC-63/0.3 L Residual Current Circuit Breaker?
The ABB F204 AC-63/0.3 L is a high-quality 4 pole residual current circuit breaker (RCCB) designed to provide dependable protection against earth leakage faults in commercial, industrial and infrastructure electrical installations. As part of the trusted ABB F200 Series, it delivers reliable protection for people and equipment while ensuring compliance with modern electrical safety standards.
Designed for applications requiring a 63 A rated current and a 300 mA residual operating current, this RCCB rapidly disconnects the electrical supply when an earth fault is detected, helping reduce the risk of electric shock and fire caused by insulation failures. The L version features the neutral terminal positioned on the left, making it suitable for installations where this wiring configuration is required.
With its compact DIN rail mounting design, robust construction and compatibility with a wide range of ABB accessories, the F204 AC-63/0.3 L offers straightforward installation, dependable long-term operation and excellent integration into modern distribution boards and switchgear assemblies.
