The Siemens 3VM14634EE320AA0 MCCB is a robust molded case circuit breaker from the advanced SENTRON 3VM series, engineered for efficient and reliable protection of electrical systems in industrial and commercial applications.
With a rated current of 630A, this MCCB is ideal for protecting feeders, motors, and distribution circuits. It offers a breaking capacity of 36kA at 415V AC, ensuring safe interruption of fault currents and enhanced system protection.
This model is equipped with a thermal-magnetic trip unit (ATFM type) featuring adjustable overload protection (Ir) and fixed short-circuit protection (Ii), allowing flexibility in system configuration and protection coordination.
Designed as a 3-pole MCCB, it supports operating voltages up to 690V AC and provides consistent performance across a wide range of electrical installations.
Built with Siemens’ high-quality engineering, the breaker ensures long mechanical life (~15,000 operations) and reliable electrical endurance, making it suitable for demanding environments.
Its compact IEC frame design and modular construction allow easy installation in control panels and switchboards, making it widely used in industries such as manufacturing, infrastructure, and power distribution.
