Siemens 3VA4195-4ED24-0AA0 — 15 A MCCB with 65 kA interrupting capacity
The Siemens SENTRON 3VA4195-4ED24-0AA0 is a 2-pole molded-case circuit breaker (MCCB) rated 15 A at 40 °C, with a TM210 thermal-magnetic release. Its interrupting capacity hits 65 kA at 240 V and 25 kA at 480 V — enough headroom for most distribution panels on a 480Y/277 V service where it still delivers 25 kA. The fixed instantaneous trip is set at 300 A (li min and max both 300 A), so it's a straight thermal-magnetic device, not a selective or electronic-trip variant. This is the system protection version (not a motor circuit protector or switch-disconnector), designed for branch-circuit and feeder protection in commercial and industrial panels. It carries a UL file designation SEAB, meaning it's UL 489 listed for the North American market.
The 15 A rating holds at 40 °C and 45 °C, then derates to 14 A at 50–60 °C, and 13 A at 65–70 °C. Plan your continuous load at 80 % of the derated value per NEC. The 65 kA at 240 V is the high-end interrupting rating; at 600 Y/347 V it drops to 14 kA, so verify the available fault current at the installation point. It's a straightforward thermal-magnetic MCCB with no add-on modules.
The 3VA4195-4ED24-0AA0 measures 75.1 mm deep, 50.8 mm wide, and 129.4 mm high. Depth at 75.1 mm (3 inches) means it clears most shallow enclosures, but check the door clearance if you're mounting a rotary handle or extended shaft.
