ELECO MGR Series RCCB | Reliable Ground-Fault Protection for Renovation & Modern Systems
Upgrading aging electrical systems presents a unique challenge: how to integrate modern safety standards without overcomplicating proven infrastructure. For engineers and contractors, the solution must be reliable, compliant, and straightforward. The ELECO MGR Series Residual Current Circuit Breaker (RCCB) is engineered to meet this exact need. As a rigorously certified IEC 61008-1 device, it delivers the essential, trusted Earth Leakage protection required for both renovation projects and new installations.
Core Flexibility: Tailored Protection Through Precise Specifications
The MGR series eliminates guesswork with its wide-ranging, clearly defined specifications, ensuring a perfect match for specific project requirements and safety codes.
•Comprehensive Ratings: Select from 2-Pole (1P+N) or 4-Pole (3P+N) models, with rated currents spanning 16A to 100A.
•Tailored Sensitivity: Select the precise level of protection with residual operating currents (IΔn) of 10 mA, 30 mA, or 100 mA, safeguarding against both shock hazards and potential fire risks.
•Robust, Trusted Performance: Built with an electromagnetic release mechanism for consistent, non-dependent tripping. It offers a high residual making & breaking capacity (IΔm) of up to 630A and a rated conditional short-circuit current (Inc) of 6 kA, ensuring reliable circuit interruption. Tripping occurs in ≤0.1 seconds at rated sensitivity.
> Value-Driven Insight: This combination of flexible sensitivity and high breaking capacity means the MGR series doesn’t just meet the standard—it provides a significant safety margin for demanding and variable electrical loads.
Engineered for Real-World Durability & Installer Ease
We design for the job site. The MGR series balances robust protection with features that save time and ensure long-term reliability.
•Installation Ready: Features universal 35mm DIN rail mounting and accommodates cables up to 35mm². The choice between lug-type and pin-type terminals offers wiring flexibility.
•Built to Withstand: A high impulse withstand voltage (Uimp) of 6000V and an IP20 protection degree defend against voltage surges and environmental contaminants, ensuring stability.
•Proven Protection Type: As a standard Type AC RCCB, it provides reliable detection of alternating sinusoidal residual currents, making it the ideal, no-fuss choice for a vast majority of applications.
