That CLASS 10 means it disconnects within 10 seconds at 7.2× rated current — fast enough to protect standard induction motors from locked-rotor heat buildup without nuisance tripping on normal starts. Spring-loaded terminals on the main current circuit accept 2x (0.25... 2.5 mm²) solid or 2x (0.25... 1.5 mm²) finely stranded with ferrule. No screw torque to check; strip to 8 mm and push in. Rated breaking capacity: 100 kA at 240 V AC, 100 kA at 400 V AC, 3 kA at 500 V AC, 2 kA at 690 V AC. The 100 kA at 400 V is the figure that matters for most industrial panels — it's high enough to achieve full selectivity with a 100 kA-rated upstream MCCB or fuse, so a downstream fault won't cascade. The 690 V rating drops to 2 kA, which still covers most motor circuits at that voltage. ## Power dissipation and derating Total power dissipation at rated current in hot operating state: 7.25 W, or 2.4 W per pole. That's low enough that you don't need to derate adjacent devices in a typical 45 mm pitch on DIN rail. Ambient operating range -20 to +60 °C; storage and transport -50 to +80 °C. Shock rated 25g / 11 ms.","metaTitle":"Siemens 3RV1011-1DA20-ZW97 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1011-1DA20-ZW97 SIRIUS motor protection circuit breaker, 3.2 A continuous, CLASS 10 trip, 100 kA breaking at 400 V, spring terminals, current lifecycle.

That's the body depth from the DIN rail mounting surface to the front of the housing — standard for the SIRIUS 3RV1 family, so it fits the same panel layout as other 3RV1 breakers."},{"question":"What wire sizes does the spring terminal accept?","answer":"The spring-loaded main terminals accept 2x (0.25... 2.5 mm²) solid or 2x (0.25... 1.5 mm²) finely stranded with ferrule.

The difference is the current rating and trip setting: the -1DA20 is 3.2 A continuous; the -1HA10 is a different rating.
