SENTRON 3VA MCCB – Microprocessor Trip
Unit (3VA2612-5HL32-0AA0)
The Siemens SENTRON 3VA2612-5HL32-0AA0 is a high-performance Molded
Case Circuit Breaker (MCCB) from the advanced 3VA2 series, equipped
with an intelligent microprocessor-based ETU320 electronic trip unit (LI
type). It is designed to provide reliable protection for low-voltage
electrical distribution systems against overload and short-circuit faults,
ensuring safe and uninterrupted operation in industrial and commercial
applications.
This MCCB features a 1250A rated current, 3-pole configuration,
and a high breaking capacity of up to 55kA at 415V AC, making it
suitable for demanding power distribution systems such as LT panels, PCCs,
MCCs, generator systems, and industrial infrastructure networks. The ETU320
trip unit offers adjustable protection settings for improved selectivity and
coordination in complex electrical installations.
Its compact modular design, high electrical endurance, and compatibility
with Siemens accessories make it ideal for modern industrial panel engineering
and power management systems.
