Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit – 3VA1110-3GE42-0AA0
The Siemens 3VA1110-3GE42-0AA0 is a SENTRON 3VA1 series molded case circuit breaker (MCCB) designed for protection of low-voltage electrical distribution systems against overload and short-circuit faults. It is widely used in industrial switchboards, MCC panels, and feeder distribution systems where reliable and compact protection is required.
This model belongs to the 3VA1 Frame 160 series and is equipped with a thermal magnetic trip unit (TM220 / ATFM – Adjustable Thermal, Fixed Magnetic). It provides adjustable overload protection and fixed instantaneous short-circuit protection, ensuring proper coordination with downstream devices.
With a rated current of 100 A and a breaking capacity of 25 kA at 415 V AC, it is suitable for industrial and commercial LT distribution systems with moderate fault levels, offering reliable feeder and incomer protection in panel boards.
