Siemens 5SV3314-3 Residual Current Circuit Breaker, 2-Pole, 40A, 30mA, Type F, Short-Time Delayed

The Siemens 5SV3314-3 is a high-performance 2-pole residual current circuit breaker (RCCB) engineered to provide robust electrical protection for both residential and commercial environments. As part of the SENTRON series, this device is specifically designed to detect fault currents, effectively safeguarding personnel and property against electric shock and potential fire hazards. With a rated current of 40A and a sensitivity of 30mA, it serves as a critical component in modern electrical distribution systems.

Advantages

This RCCB features advanced Type F technology, which offers enhanced protection by detecting both AC residual currents and pulsating DC residual currents. The short-time delayed operation is a significant benefit, as it prevents nuisance tripping caused by transient surges or high-frequency interference, ensuring continuous power supply. The device is built with integrated touch protection for increased safety during installation and maintenance. Furthermore, the tool-free mounting system allows for quick removal from DIN rails or busbar assemblies using a simple manual slide, streamlining the installation process.

Suitable for

• Residential electrical distribution boards
• Commercial building power systems
• Circuits containing frequency converters or single-phase inverters
• Installations requiring protection against nuisance tripping

When it may not be suitable

This device is not intended for use in DC-only electrical systems or high-voltage industrial applications exceeding its rated voltage. It should not be used as a primary protection device for circuits requiring Type B or Type AC-only characteristics unless specified by the system design.

Key specifications

• Number of poles: 2
• Rated current: 40A
• Rated residual current: 30mA
• Type: F (short-time delayed)
• Rated voltage: 230V AC
• Mounting: DIN rail

How to use

The device is designed for mounting on a standard DIN rail within an electrical distribution cabinet. Installation should be performed by a qualified electrician in accordance with local electrical codes. Once mounted, the device can be connected to the incoming and outgoing power lines. The manual slide mechanism allows for easy installation and removal without specialized tools. Users can scan the Data Matrix code on the device housing using the Siemens Industry Online Support App to access detailed technical documentation and support information.

What to consider before purchase

• Verify that the 40A rated current matches your circuit load requirements.
• Ensure the 30mA sensitivity is appropriate for the intended level of personnel protection.
• Confirm that Type F is the correct classification for the equipment connected to the circuit.
• Check the available space in your distribution board for a 2-pole device.

Usage recommendations

Regularly test the functionality of the residual current circuit breaker using the integrated test button to ensure the mechanism remains operational and provides reliable protection over time.
