The Siemens 3VA2110-5JP32-0DC0 is a SENTRON molded case circuit breaker rated for 100 A continuous current with an adjustable thermal-magnetic trip range from 150 A minimum to 1 200 A maximum — meaning you set the pickup to match the load, not the other way around. It is a 3-pole unit built for line protection, so it sits at the feeder or branch in a distribution panel, not on a motor starter. The interrupting ratings are the headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. Thermal performance is flat across the board: 100 A at 40 °C, 45 °C, 50 °C, 55 °C, 60 °C, 65 °C, and 70 °C. No derating curve to calculate — if the ambient inside the panel hits 70 °C, this breaker still holds its full 100 A rating. That saves you a frame size upgrade in a hot enclosure.
The two HQ aux switches give you status feedback (open/closed/tripped) for the PLC or annunciator without adding external relays. It also carries a communication function, so it can talk to a higher-level system for metering or remote trip indication — useful in a monitored distribution panel where you want to know which breaker opened before you walk the floor.
Panel fit and environmental range
The storage limit is the handling limit — if it sat in an unheated warehouse at -40 °C, it's fine once it warms up before energizing.
For a BOM freeze or a panel that was specified around the 3VA1110-5EF32-0AM0, this 3VA2110-5JP32-0DC0 is a different frame and trip range — the 3VA1110 is a 160 A frame, this is a 1 200 A frame. They are not drop-in interchangeable; check the panel cutout and bus bar spacing before substituting.
