Circuit breakers

Eaton´s FRCdM range of voltage-independent residual current circuit breakers (RCCB) is your comprehensive solution for fault protection, additional protection, and fire protection.

FRCdM digitally assisted RCD function offers best-in-class performance in regards of system availability and reliability of fault current protection. The current system status can be communicated through an integrated auxiliary contact.

FRCdM offers more flexibility in applications due to extensive certification and ratings. Superior protection is given with the xEffect range of RCCBs and is the solution for critical systems.

Highest safety

Voltage independent tripping

Be informed and not surprised

Live status communicated through integrated contact

Better system resilience

Digital assisted sensing of residual current

Core features

Line voltage independent RCCB for fault protection, additional protection as well as fire protection
Live status of the system communicated through an integrated auxiliary contact as well as on the device itself
Digital assisted sensing of residual current to achieve the highest levels of system availability
Reduced running costs due to a yearly test interval
Ratings from 25A to 80A
3+N pole configuration
Fault current tripping indicator enables to determine of the tripping reason

xEffect digital switchgear

The digital RCCBs from the xEffect series can do more than just switch off. They monitor electrical installations and give advance warning of critical current flows. So that system shutdowns – and the associated costs – can be avoided.

Local indicators

Green

The system is in normal operation.

Yellow

The currently measured residual current is higher than 30% I∆n. The system is currently drawing fault current, and actions should be taken accordingly

xEffect Residual Current Circuit Breaker FRCdM Type AC, A, U, R - red LED

Red

The currently measured residual current is higher than 50% I∆n. The system is currently drawing a critical amount of fault current, and actions should be taken immediately.

Reliable protection for machines

These products help maintain an optimal system and provide additional protection against residual earth leakage currents for a wide range of applications. They come with different tripping characteristics to cater for variety of electrical systems and components. The devices offer a wide range of nominal currents and comprehensive optional accessories.

Sensitivity Type A

These types are capable of sensing pulsating residual currents and are not negatively affected by a DC overlay of up to 6mA.
These devices (depending on the range) are also available as:

G/A short time delayed devices which are surge current proof up to 3kA. These devices enable a reliable and safe installation with increased system availability.
S/A selective RCCBs with improved surge current capabilities up to 5kA. These devices are selective (conditions apply) to other RCDs and enable special applications and root installations.

Sensitivity Type F

These types are capable of sensing pulsating residual currents and are not negatively affected by a DC overlay of up to 10mA .
These devices (depending on the range) are also available as:

G/F short time delayed devices which are surge current proof up to 3kA. These devices enable a reliable and safe installation with increased system availability.
S/F selective RCCBs with improved surge current capabilities up to 5kA. These devices are selective (conditions apply) to other RCDs and enable special applications and root installations.

Type F residual current devices offer the following benefits:

Increased Protection

Increased protection thanks to detection of mixed frequencies and higher load rating for DC residual currents up to 10mA

Reliable protection

Reliable protection for machines with 1-phase frequency converters

Reduction of nuisance tripping

Reduction of nuisance tripping thanks to time-delayed tripping and high current withstand capability

Wide range of electronical loads is possible

Load profile is consist of electronical loads such as power supply units

One device with variety of loads

Various electronical loads are connected to one main RCD

Maximum safety in railway applications

The xEffect range of protective switchgear also ensures highest standards of safety in railway applications. Thanks to compliance with specific standards such as IEC 61373 (Rolling stock equipment – Shock and vibration) and EN 45545-2 (fire protection of railway vehicles), the devices provide maximum safety and performance in rolling stock applications. In addition to standard switchgear, we also offer a wide range of MCBs and RCDs for the connection of ring cable lugs in railway applications.
