Siemens 3RV2 Series Electronic Circuit Breaker, 20A Current, 4kA Breaking Capacity - 3RV2421-4BA15
This electronic circuit-breaker provides adjustable thermal–magnetic protection for three-phase systems and is intended for transformer and motor protection within industrial control installations. It operates across a wide voltage band and integrates a transverse auxiliary switch for signalling, making it suitable for DIN-rail distribution panels and control racks in automated environments.
Features & Benefits
• Adjustable overload 13 to 20 A enabling tailored motor protection
• Breaking capacity 4kA at 690V for high-voltage fault clearing
• Trip class CLASS10 for controlled thermal response
• Transverse auxiliary switch 1NO+1NC for status feedback
• Screw terminals accept up to 2x10 mm² conductors for robust connections
• Protection up to 690V and frequency 50 to 60 Hz for versatile application
• Breaking capacity 4kA at 690V for high-voltage fault clearing
• Trip class CLASS10 for controlled thermal response
• Transverse auxiliary switch 1NO+1NC for status feedback
• Screw terminals accept up to 2x10 mm² conductors for robust connections
• Protection up to 690V and frequency 50 to 60 Hz for versatile application
Applications
• Suitable for transformer secondary protection in switchgear
• Ideal for motor starters and three-phase motor circuits
• Used with DIN-rail control panels in automation cabinets
• Can be used for branch circuit protection in industrial plants

What connection types does it accept for main and auxiliary circuits?
Main and auxiliary connections use screw terminals compatible with solid, stranded and finely stranded conductors, including dual conductors where specified.
How does it behave under short-circuit conditions at different voltages?
The device employs a magnetic short-circuit trip with rated Icu values that vary by voltage, offering higher breaking capability at lower voltages and 4kA at the upper rated voltage.
What environmental ranges can it withstand during storage and operation?
It is specified for operation between −20°C to +60°C and for storage or transport between −50°C to +80°C, with permitted relative humidity up to 95% during operation.
How is mounting achieved and what panel spacing is needed for live parts at 690V?
It mounts on 35mm DIN rail with Snap-on and screw fastening
live-part spacing for 690V requires 50mm clearance vertically and 30mm laterally.
