    Ex9LE RCD add-on blocks are intended for combination with Ex9BH and Ex9BN circuit breakers, meeting the requirements of IEC / EN 61009. Versions for all pole variants of Ex9BH and ExBN breakers are available and thus enable various combinations of apparatuses integrating the functionality of a residual current device with over-current protection. Compared to magnetic conception, this state-of-the-art electronic technology brings advantages consisting in a more precise evaluation of the residual current and further significantly extends the device's operational reliability. The electronic version does not face the difficulty of armature magnetisation like conventional magnetic devices, while regular testing is required by the standards to detect and eliminate this issue. For Ex9LE modules, regular testing is required only in order to formally meet the requirements of standards and other mandatory legal documents; recommended interval is one year.

    Devices are provided for the entire range of nominal currents of attached circuit breakers, i.e. up to 63 A. Nominal residual current can be selected out of 10, 30, 100 or 300 mA. Conditional short-circuit resistance is determined by the breaker’s tripping capacity, i.e. 10 kA for the combination of Ex9LE with Ex9BH and 6 kA for Ex9LE with Ex9BN.

    • For combination with MCBs Ex9B
    • Conditional rated short circuit strength Inc 10 kA in combination with Ex9BH and 6 kA with Ex9BN
    • 1+N up to 4-pole versions
    • Rated residual current 10, 30, 100, 300 mA
    • Rated currents up to 40 and 63 A
    • Rated operational voltage 230/400 V AC
    • AC type of RCD

RCCBO Ex9CBL

Modular combined residual current devices with circuit breaker, with a breaking capacity of 10 kA for Ex9CBL-H Series and 6 kA for Ex9CBL-N Series. The devices meet the requirements of the standard IEC / EN 61009. These protectors are intended for household and industrial applications. They provide 50 per cent space economy compared to separate residual current device and separate circuit breaker.

RCCB Ex9CL

Modular residual current devices Ex9CL-H and Ex9CL-N in two or four-pole design. Technology is based on the classical principle of permanent magnet and electromagnetic armature, providing full voltage independence of protective functions. Circuit breakers comply with the requirements of the standards IEC/EN 61008-1.
