Siemens, SENTRON, 3VA5 Molded Case Circuit Breaker 3-Pole 400A, Breaking Capacity 35 kA, Fixed

This moulded case circuit-breaker provides overcurrent protection for three-phase systems in industrial and commercial installations. Designed for fixed mounting, it performs interruption and fault-limiting duties across alternating and direct voltage networks commonly found in automation, electrical and mechanical environments.

• 400A rated current for high-load circuit protection
• 35 kA interrupting capability for severe fault clearing
• Thermal-magnetic trip unit offering adjustable overload and short-circuit response
• 3-pole configuration enabling simultaneous disconnection of all phases
• Rated to 690V AC for broad industrial supply compatibility
• 500V DC rating supporting DC distribution applications

• Suitable for distribution panels in manufacturing plants
• Ideal for motor control and protection in automation systems
• Used with switchboards in large commercial buildings
• Can be used for DC-fed equipment protection in battery-backed systems

It is intended for fixed installation and must be secured to a panel or enclosure designed to accept fixed-mount MCCBs.

All three poles operate together so that phase conductors are disconnected simultaneously upon tripping.

The unit is supplied without integrated Terminal accessories, allowing use with customer-selected connection hardware.
