Siemens 5SV3314-6KL Residual Current Circuit Breaker, 2-Pole, 40A, 230V, Type A

The Siemens 5SV3314-6KL is a high-performance 2-pole residual current circuit breaker (RCCB) engineered to provide robust electrical protection in residential and commercial environments. This device is designed to monitor electrical circuits and automatically disconnect power when a fault current is detected, significantly reducing the risk of electric shock and fire hazards. By adhering to strict safety standards, it ensures reliable operation and long-term durability for modern electrical installations.

Advantages

This residual current circuit breaker offers exceptional reliability and precision in detecting both alternating and pulsating direct fault currents, which is characteristic of Type A devices. Its robust construction ensures consistent performance under varying load conditions, providing peace of mind for both installers and end-users. The compact 2-pole design allows for efficient space utilization within distribution boards, while the high-quality materials used in its manufacturing guarantee a long service life and resistance to environmental factors.

Suitable for

• Residential electrical distribution boards
• Commercial building power systems
• Protection of lighting and socket circuits
• Preventing electrical hazards in damp or high-risk areas

This device may not be suitable for industrial applications requiring higher current ratings or specific protection against high-frequency fault currents. It is also not intended for use in DC-only electrical systems or environments where specialized protection devices are mandated by local regulations.

Key specifications

• Number of poles: 2
• Rated current: 40A
• Rated voltage: 230V
• Type: A
• Residual current sensitivity: 30mA

Installation should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. The device is mounted onto a standard DIN rail within a distribution enclosure. Ensure that the supply voltage matches the device specifications before connection. Once installed, the integrated test button should be pressed periodically to verify the mechanical functionality of the tripping mechanism.

What to consider before purchase

• Verify the total load of the circuit to ensure the 40A rating is sufficient
• Confirm that the installation environment is compatible with Type A protection requirements
• Check the available space in your distribution board for a 2-pole device

Usage recommendations: It is recommended to perform a functional test using the integrated test button at least every six months to ensure the device remains in optimal working condition. Always ensure that the circuit breaker is protected by an upstream miniature circuit breaker to prevent overload and short-circuit damage.
