Residual Current Device Siemens 5SV33143: advanced safety for installations with single-phase inverters

The Siemens 5SV33143 Type F residual current device is an essential safety device for protecting people against earth leakage currents. With a rated current of 40A and a sensitivity of 30mA, it ensures quick and precise intervention in case of a fault, immediately cutting off the power and preventing the risk of electric shock.

This model belongs to the 5SV3 series, designed by Siemens to offer maximum reliability and durability even under intensive use, both in residential and professional environments.

Function and differences with other types of residual current devices

A residual current device protects people, not electrical devices. In the presence of leakage currents, the safety switch cuts off the power, preventing the current from passing through the human body. However, it does not offer protection against overvoltages or short circuits, for which a dedicated circuit breaker is necessary.

Type F technology: protection for modern devices

Type F residual current devices, compliant with CEI EN 62423 standards, have been developed to ensure safety in installations with devices equipped with single-phase inverters, such as:

  • Heat pumps and inverter air conditioners

  • Washing machines, dryers, and dishwashers

  • Electronic and industrial equipment with frequency converters

This type is positioned between type A and B residual current devices, offering greater sensitivity to fault currents at variable frequencies, which standard models (AC or A) cannot detect. The short intervention delay reduces unwanted trips due to transient micro-leakages, maintaining high safety levels.

Siemens quality and reliability

The Siemens 5SV33143 is built with high-quality materials, in a compact 2 DIN module format, easily installable in standard electrical panels. Siemens technology ensures precise intervention, long-term stability, and certified safety, making it an ideal choice for modern electrical installations updated to the latest standards.
