Product Description
The Siemens 5SV3644-6 Residual Current Circuit Breaker (RCCB) is an advanced protective device designed to safeguard both personnel and equipment against earth leakage and electrical faults. Rated for 40A operation, this four-pole unit offers a trip sensitivity of 300 mA, tailored for Type A protection scenarios. As part of the Siemens Sentron 5SV3 Series, it ensures high reliability and consistent performance in installation environments requiring rigorous safety standards.
Key engineering features include its electromagnetic tripping mechanism, capable of instantaneous break times and handling surge currents greater than 1 kA. The RCCB's DIN rail mount form factor integrates neatly into standard electrical distribution panels within residential, commercial, or industrial facilities. Equipped with a robust toggle switch actuator and screw terminal connections, setup and maintenance are straightforward.
This circuit breaker operates at a nominal 400V AC, offering a breaking capacity of 0.8 kA and earth leakage protection conforming to Type A requirements, which covers both AC and pulsating DC residual currents. Its certified IP20 enclosure helps prevent accidental contact and provides durable protection against dust and basic ingress risks.
The 5SV3644-6 is certified under numerous global standards, including CE, EAC, CCC, UKCA, and VDE, assuring compliance for international projects. It’s engineered for long service life with an equipment lifespan exceeding 10,000 switching cycles and an ambient working range from -25°C to +45°C. Its silicone-free design broadens compatibility for sensitive environments.
Application areas include residential safety installations, industrial machinery protection, and fire-prevention systems - delivering efficient and safe operation across a wide spectrum of power distribution use cases. The instant tripping characteristic ensures rapid response to detected faults, minimizing downtime and risk.
Physical specifications cover a compact footprint (90mm height, 72mm width, 70mm depth) suitable for panel installations, with secure screw terminals and a sturdy toggle switch for manual resetting after a fault. This RCCB is ideal for projects demanding reliable earth leakage protection and regulatory compliance.
