Siemens 2-pole residual current circuit breaker 5SV3314-6 40A 230V type A 30mA

The Siemens 2-pole residual current circuit breaker model 5SV3314-6 is designed for reliable electrical circuit protection in residential and commercial applications. Operating at 230 V with a rated current of 40 A and a sensitivity threshold of 30 mA, this type A device provides essential safety against electric shock and fault currents. It is engineered to integrate seamlessly into standard electrical distribution boards to safeguard circuits and users effectively.

Advantages

This Siemens residual current circuit breaker ensures a high level of safety by rapidly disconnecting the power supply when residual currents are detected, thus reducing the risk of electrical shock. The unit is built to stringent quality standards, offering long-term reliability and stable performance in everyday electrical installations. Its standard modular width allows for straightforward mounting on standard DIN rails within electrical enclosures, making it a practical choice for both professional installers and certified electricians.

Suitable for

• Residential electrical installations for socket and lighting circuits
• Commercial building sub-distribution boards
• Protection against direct and indirect contact with live parts
• Detection of sinusoidal alternating currents and pulsating direct currents

This device may not be suitable for industrial environments requiring specialized protection types other than type A, or for circuits operating outside its specified voltage and current ratings. It should not be used as a standalone overload or short-circuit protection device without a properly coordinated miniature circuit breaker.

Key specifications

• 2-pole configuration (1+N)
• Rated current: 40 A
• Rated operational voltage: 230 V
• Residual current sensitivity: Type A
• Rated residual operating current: 30 mA
• Width in modular units: 2TE

Installation must be performed by a qualified and licensed electrician in accordance with local electrical safety regulations and wiring standards. Prior to installation, ensure that the main power supply is completely switched off and locked out. Mount the device securely onto a standard DIN rail inside the distribution enclosure and connect the line and neutral conductors to the clearly marked terminals, ensuring proper torque is applied to all screw connections to prevent loose contacts.

Before purchasing this residual current circuit breaker, verify that the technical parameters such as rated current, voltage, and sensitivity match the requirements of your specific electrical system. Ensure that there is adequate physical space within your distribution board, as the unit requires two modular units of width. Confirm whether a type A device is appropriate for the types of loads connected to the circuit, such as household appliances with electronic components.

Regularly test the residual current circuit breaker by pressing the integrated test button every six months to verify correct mechanical and electrical functionality. Inspect the enclosure and connections periodically for any signs of wear, discoloration, or loose wiring.
