The Siemens SENTRON 3VA10252ED420AA0 MCCB is a high-performance molded case circuit breaker designed to provide dependable protection against overloads, short circuits, and electrical faults in low-voltage power distribution systems. As part of the globally trusted SENTRON 3VA Series, this MCCB delivers reliable switching performance, enhanced operational safety, and long service life for industrial, commercial, and infrastructure applications. SENTRON 3VA MCCBs are engineered to protect cables, motors, generators, starters, and power distribution networks with advanced protection technologies and a modular accessory platform.
The 3VA10252ED420AA0 features a 25A rated current, 4-pole configuration, and a Thermal Magnetic Trip Unit utilizing FTFM (Fixed Thermal Fixed Magnetic) protection technology. This protection system combines a thermal release for overload protection and a magnetic release for instantaneous short-circuit protection, ensuring comprehensive circuit protection within a compact device. Thermal-magnetic trip units are widely used in low-voltage distribution systems where reliability and simplicity are essential.
In modern electrical installations, overload conditions and fault currents can lead to equipment damage, costly downtime, and safety risks. The Siemens 3VA10252ED420AA0 MCCB continuously monitors circuit conditions and automatically interrupts power when abnormal current levels are detected. This helps protect motors, transformers, switchgear assemblies, control panels, distribution boards, and electrical cables from damage caused by electrical faults. SENTRON 3VA MCCBs are specifically designed to provide reliable overload and short-circuit protection for industrial and commercial power distribution systems.
The compact design enables easy installation in LT Panels, PCC Panels, MCC Panels, Distribution Boards, Switchgear Assemblies, Motor Control Centers (MCCs), OEM Equipment, and Industrial Automation Systems. Siemens' robust engineering standards ensure excellent mechanical durability, dependable fault interruption, and reduced maintenance requirements throughout the product lifecycle.
