2CSF204123R3400 ABB F204 A-40/0.3-L RCCB 4P Type A 300mA 40A

Why Choose the ABB F204 A-40/0.3-L RCCB?

The ABB F204 A-40/0.3-L, order code 2CSF204123R3400, is a 4-pole Type A residual current circuit breaker (RCCB) designed to provide dependable residual current protection in three-phase electrical distribution systems. Part of the established ABB F200 / FH200 RCCB product group, this model features the neutral connection on the left and is suitable for residential, commercial and industrial installations.

This RCCB has a rated current of 40 A and a rated residual operating current of 300 mA. Its Type A characteristic enables detection of sinusoidal AC residual currents and pulsating DC residual currents, providing appropriate protection for circuits containing many common electronic loads.

The 4-pole configuration is designed for three-phase electrical distribution, while its 230/400 V AC rating and compact four-module DIN rail format make it straightforward to integrate into compatible distribution boards. With a rated insulation voltage of 500 V and impulse withstand voltage of 4 kV, the F204 A-40/0.3-L provides robust ABB residual current protection for professional installations.

Key Advantages

• Reliable ABB Type A residual current protection for modern electrical installations.
• 40 A rated current for appropriately rated distribution circuits.
• 300 mA residual current sensitivity for earth leakage protection.
• Detects both sinusoidal AC and pulsating DC residual currents.
• 4-pole configuration for three-phase electrical distribution.
• Neutral on the left for installations requiring this terminal arrangement.
• Compact four-module DIN rail format for modular distribution boards.

Key Features

• ABB F200 series RCCB.
• Type A residual current characteristic.
• 4-pole configuration.
• 40 A rated current.
• 300 mA rated residual current.
• 230/400 V AC rated voltage.
• 50/60 Hz rated frequency.
• Detection of sinusoidal AC and pulsating DC residual currents.
• Left-side neutral arrangement.
• DIN rail mounting for modular electrical installations.
• Designed to meet IEC/EN 61008-1 and IEC/EN 61008-2-1.

Type A Residual Current Protection with Left-Side Neutral

Type A RCCBs are designed to respond to both sinusoidal AC residual currents and pulsating DC residual currents. This makes the ABB F204 A-40/0.3-L suitable for electrical circuits containing equipment with electronic components that can produce pulsating DC earth leakage in addition to conventional AC residual currents.

The -L configuration provides the neutral connection on the left, making this version useful where the distribution board layout or established installation convention requires this terminal arrangement. As an RCCB, the F204 A-40/0.3-L does not incorporate overload or short-circuit protection, so appropriate overcurrent protection must be provided separately. Its 300 mA sensitivity should also be distinguished from 30 mA devices typically specified where additional protection against electric shock is required.

Typical Applications

• Commercial electrical distribution systems.
• Industrial electrical installations.
• Residential three-phase distribution boards.
• Three-phase circuits requiring 4-pole residual current protection.
• Installations requiring a left-side neutral connection.
• Circuits supplying equipment capable of producing pulsating DC residual currents.
• Building services and electrical distribution equipment.
• Installations requiring 300 mA Type A residual current protection.
