Type A-SI Auto-Reclosing Residual Current Device |40 amps|30mA|2-pole (N+L)| with official certifications and CE

• INCLUDES CABLES PREPARED TO CONNECT THE DIFFERENTIAL AND THE RECLOSER. Auto-reclosing is the automatic control mode (reclosing time 10, 60, 300s); it is the same LNRN3 recloser that we have been using for years in our differentials and that has been so well received by customers. It has the option, through external relays, to provide circuit opening and closing even remotely via Wi-Fi.
• Super-immunized Residual Current Device Si curve A, 40 Amps and 30mA. Manual in Spanish. If you have any questions during installation, call us, we are here to help you. 99.99% of cases are resolved with a simple call.
• Maximum short-circuit current 6Ka, 220/230v. Automatic, manual and closed selection (allows connecting a padlock).
• Important: The residual current device cannot be set to the ON position in most cases until the recloser is connected and energized to perform the first cycle. Complies with IEC61008, EN61008 and CE standards. You can request a copy of the CE certificates and test reports.

The different types:

According to the international standard IEC 60755, they are classified according to their ability to detect different residual current waveforms and are divided into type AC, A, F, B residual current devices. Type AC residual current devices were the first to be commercialized and are especially used in residential systems. They detect alternating residual current at the mains frequency of 50/60 Hz and are suitable for linear loads.

Type A devices work best with sinusoidal AC currents and sudden unidirectional currents and can replace type AC. Type B residual current devices are ideal for operating with DC or high-frequency currents and are suitable for use in the presence of non-linear circuits and in the installation of electric vehicle charging points.

Type F residual current circuit breakers, where F stands for Frequency, are an evolution of the type A residual current protection device and also work with multi-frequency current. They are designed for protection against indirect contact of devices equipped with inverters.

Although the type F residual current device is the least used, professionals are beginning to install it in both industrial and residential environments.
