Why Choose the ABB F404A-S63/0.3 RCCB?
The ABB F404A-S63/0.3 is a four-pole selective Type A residual current circuit breaker (RCCB) designed for the ABB SMISSLINE TP plug-in distribution system. Rated at 63 A with a rated residual operating current of 300 mA, it provides residual-current protection for three-phase and neutral circuits where selective coordination is required.
As a Type A RCCB, the F404A-S63/0.3 is designed to respond to sinusoidal AC and pulsating DC residual currents. Its selective S-type characteristic incorporates delayed operation to support discrimination with appropriately selected downstream residual-current protection devices, helping limit disconnection to the circuit closest to a fault.
Developed specifically for the ABB SMISSLINE TP system, the F404A-S63/0.3 combines selective residual-current protection with direct conductor-bar mounting. Its 230/400 V AC rating, four-pole configuration and compact four-module design make it suitable for coordinated commercial and industrial distribution assemblies.

Reliable Selective Residual-Current Protection
The ABB F404A-S63/0.3 provides selective residual-current protection for installations where coordination between upstream and downstream protective devices is required. Its delayed S-type response allows an appropriately selected downstream residual-current device to operate first, helping minimise unnecessary interruption of unaffected circuits elsewhere in the distribution system.
Its Type A characteristic provides detection of sinusoidal AC and pulsating DC residual currents, while the 300 mA sensitivity is suited to coordinated upstream residual-current protection applications. Direct integration with the SMISSLINE TP conductor-bar system further supports efficient construction, modification and expansion of modular distribution assemblies.
Typical Applications
- Commercial electrical distribution systems.
- Industrial SMISSLINE TP distribution panels.
- Three-phase and neutral electrical distribution circuits.
- Upstream residual-current protection requiring selective coordination.
- Installations with appropriately coordinated downstream residual-current protection devices.
- Modular electrical distribution systems requiring Type A residual-current detection.
