CDM3E Electronic MCCB – 4 Pole | Adjustable LSI Electronic Trip | 32A–800A | 50kA ICU
The Delixi CDM3E Electronic Molded Case Circuit Breaker (MCCB) is an advanced industrial circuit protection solution engineered for electrical distribution systems requiring electronic trip protection, adjustable fault management, and enhanced protection precision.
Built with LSI (Long-Time, Short-Time, Instantaneous) Electronic Trip technology, the CDM3E Series delivers intelligent overload protection and improved fault coordination compared to conventional thermal-magnetic MCCBs.
The adjustable electronic protection mechanism allows optimized system configuration for industrial facilities, switchgear panels, critical infrastructure, manufacturing plants, and heavy-duty power distribution systems.
Designed in a 4 Pole (4P) configuration, this MCCB provides protection suitable for complex three-phase electrical networks requiring neutral line protection and enhanced operational reliability.
Supporting current ratings from 32A up to 800A and providing a fault interruption capability of 50kA ICU, the CDM3E series is engineered for demanding industrial environments where protection precision and reliability are essential.
Manufactured according to IEC 60947-2 international standards, the Delixi CDM3E combines intelligent electronic protection with industrial-grade performance.
