The Siemens 3RV2032-4SA15 is a SIRIUS motor protection circuit breaker rated for 14 A at 480 V and 14 A at 600 V, with a breaking capacity of 50 kA at 400 V.
Mounting & panel fit
The body is 55 mm wide, 140 mm tall, 149 mm deep — a standard 3-module footprint that fits most motor starter combos. Any mounting position works, so you can lay it sideways in a tight gland plate if needed.
The integrated auxiliary contact switches 1 A at 24 V, 0.15 A at 60 V, and 0.5 A at 230 V. At 110 V, 125 V, and 220 V it is rated 0 A — meaning no make/break capability at those voltages; use a separate contact block if your control circuit lands there.
The interrupting rating varies with line voltage: 100 kA at 240 V, 50 kA at 400 V, 10 kA at 500 V, and 5 kA at 690 V. At 240 V it also carries a 3 hp motor rating.
