Digital Combined RCD/MCB Devices and Type B+ Digital Residual­Current Circuit-Breakers From Eaton

After the development of the digital residual­current circuit-breaker, Eaton's Electrical Sector - is expanding its product range with a digital combined RCD/MCB device and a digital residual­current circuit-breaker with type B+ tripping characteristics. This top quality, efficient series will be available to customers under the name xEffect.

Digital Combined RCD/MCB for Upscale Residential and Commercial Building Applications
Thunderstorms or temporary faults do not affect the digital circuit-breaker with the type G short-time delay and optimized tripping threshold. The digital combined RCD/MCB device permanently monitors the actual state, registers possible faults and indicates this on three LEDs. If the current flow in the installation moves to ground in the range between zero and 30 percent of the rated residual current, a green LED indicates the normal state. A yellow LED indicates a differential current between 30 and 50 percent of the rated residual current and thus shows that the combined RCD/MCB device is approaching its tripping threshold. If the LED is red, the leakage current has already exceeded 50 percent of the rated residual current. The installation is thus in a critical state – the digital combined RCD/MCB device trips if the residual current increases any further and the tripping limit is reached.

The Service mode helps qualified electricians to determine the level of the residual current present (milliamp increments) in the shortest possible time. If the electrician presses the corresponding Service button, the flashing LED will indicate the range of the residual current level. This enables measures to be taken quickly in order to maintain system availability. The circuit-breaker combines the most advanced safety features in an extremely compact design (width: two width modules).

Type B+ Digital Residual­Current Circuit-Breaker for Special Fire Protection:
The digital residual­current circuit-breaker also shows the actual residual current present in real-time – the three LEDs and isolated auxiliary contacts are used for external indication. It detects and reliably disconnects all types of residual current, as well as DC residual currents and residual currents in the high frequency range. The digital residual­current circuit-breaker thus meets all the requirements for increased fire protection in accordance with EN/IEC 62423, as well as the residual­current circuit-breaker product standard IEC 61008. The Eaton residual­current circuit-breaker with the type B+ tripping characteristics is therefore particularly suitable for industrial systems using frequency inverters, and it is also used with sophisticated PV installations, as well as in all sectors involving a high proportion of electronics, i.e. where there is the probability of DC residual currents occurring.

Both the digital combined RCD/MCB device and the type B+ digital residual­current circuit-breaker are fitted on DIN rails (clamp and screw terminals) and when installed are protected to IP 40.
