The residual current device Siemens 5SV33123 is designed to ensure maximum safety for people against current leakage and indirect contact, promptly interrupting the circuit in case of a fault to earth. With a rated current of 25 amperes and a sensitivity of 30 milliamperes, this device is the ideal choice for modern civil and residential installations.
The Siemens residual current device acts by detecting abnormal leakage currents to earth: when these exceed the limit value of 30mA, the device immediately cuts off the power, preventing the risk of electric shock. Being a pure residual current device, it protects people but not circuits from overloads or short circuits. For complete protection of the installation, it is advisable to pair it with a circuit breaker.
Type F residual current devices, introduced according to the CEI EN 62423 standard, offer advanced protection compared to traditional AC or A type models. They are specifically designed to handle variable frequency fault currents generated by appliances with single-phase frequency converters, such as:
Heat pumps
Washing machines and dryers
Inverter air conditioners
Advanced electronic equipment
The short time delay ensures stability and reduces unwanted disconnections due to transient micro leakages.
The Siemens 5SV33123 residual current device belongs to the 5SV3 series, synonymous with safety, durability, and precision in operation. The compact 2 DIN module construction makes it suitable for domestic and industrial electrical panels, ensuring easy installation and compatibility with all standard distribution systems.
