Smart Residual Current MCCB

Our Smart Residual Current MCCBs represent a critical component for modern electrical distribution systems requiring both fault protection and smart management capabilities. These MCCBs are designed to operate at AC400/50Hz and are available in 3P+N pole configurations, covering frame currents from 125A to 800A. Each unit incorporates AC-type residual current protection with both delayed and non-delayed characteristics, alongside a three-stage electronically adjustable system for overload and short-circuit protection. This combination ensures precise and adaptable fault clearance, minimizing downtime and protecting equipment.

Beyond core protection, these intelligent MCCBs offer integrated communication via RS485, with optional infrared capabilities, allowing for seamless integration into building management systems or industrial control networks. The devices also feature an auto re-closing function, with an adjustable time range of 20 to 60 seconds, which can improve system availability by automatically restoring power after transient faults. With compliance to IEC60947-2, CE, CB, and RoHS, these MCCBs are suitable for deployment across Asia, Europe, South America, Africa, and Oceania, providing a reliable and compliant solution for engineers, panel builders, and procurement managers seeking advanced circuit protection with smart features.
