Its CLASS 20 trip curve means it allows up to 20 seconds of locked-rotor current before tripping — standard for general-purpose induction motors driving pumps, fans, and conveyors where the start-up transient isn't extreme. Breaking capacity is 100 kA at both 240 V and 400 V AC, dropping to 15 kA at 500 V and 10 kA at 690 V. No ground-fault detection on this variant — if you need that, you're looking at a different 3RV family member.
Zero clearance required at the back or sides — you can butt it against adjacent devices without derating. Any mounting position works, which simplifies layout in tight enclosures. Dimensions are 70 mm wide, 165 mm tall, 174 mm deep. Main circuit terminals accept solid conductors 2x (2.5 to 16 mm²) or stranded 2x (10 to 50 mm²) and 1x (10 to 70 mm²). That's generous lug capacity for a 50 A breaker — no adapter blocks needed for the heavier feeds.
RoHS compliance date is July 1, 2006, meaning it meets the original EU RoHS directive. REACH and other regional compliance documentation is available from the manufacturer.
