160 A continuous, single-pole — the interrupting capacity that matters
The Siemens 3VA1116-3ED16-0AA0 is a 1-pole SENTRON molded case circuit breaker rated 160 A continuous at 40 °C through 50 °C — no derating needed until ambient hits 55 °C, where it steps to 158 A. That 160 A hold across a 10 °C band means it handles a warm panel without tripping early. Interrupting capacity is 52.5 kA at 240 V AC and 7.5 kA at 415 V AC — the 240 V figure covers most North American panelboard fault duties, while the 415 V number tells you it's not a high-fault device for 400 V industrial mains. Match it to a service with available fault current below that ceiling.
TM210 trip, line protection, and the 1-inch slot
The TM210 thermal-magnetic trip unit is fixed — no interchangeable trip blocks, no ground-fault module, no communication. It's a straight line-protection breaker for feeder or branch circuits where you need thermal overload and magnetic short-circuit response only. Physical footprint is 130 mm high, 25.4 mm wide, 70 mm deep — that 25.4 mm (1 inch) width per pole is the standard MCCB module.
