Siemens SIRIUS 3RV2 Series Motor Protection Circuit Breaker, 20A Current Rating, IP20 - 3RV2021-4BA15-0BA0

This motor protection circuit‑breaker provides adjustable overload and magnetic short‑circuit protection for three‑phase motors in industrial control systems. It is designed for use where thermal overload and instantaneous magnetic trips are required to protect motors operating across a wide voltage range and under variable ambient conditions.

Features & Benefits

• Adjustable overload 13–20 A for correct motor thermal protection
• Instantaneous trip at 260A to limit short‑circuit stress
• Rated operational current 20A for AC‑3 motor switching duties
• Breaking capacity up to 100kA at 240V for high fault tolerance
• Operates on supply 20–690 V supporting broad installation needs
• Auxiliary transverse switch 1NO+1NC for signalling and interlocks

Applications

• Suitable for protecting three‑phase motors in conveyor drives
• Ideal for motor control centres in manufacturing plants
• Used with contactor combinations in pump stations
• Can be used for retrofit motor protection in panel upgrades

What mounting options are available for installation?

It mounts on a 35 mm DIN rail and can be fixed by screw and snap‑on methods for Compact panel layouts.

How does the device cope with extreme ambient temperatures?

It is specified to function from −50°C to +60°C during operation and endures storage and transport down to −50°C and up to +80°C.

What conductor sizes can be connected to the main terminals?

Main contacts accept solid or stranded conductors in ranges up to 2x10 mm² and, with ferrules, single conductors up to 10 mm² depending on configuration.

Which short‑circuit protection devices are recommended for auxiliary circuits?

For auxiliary protection use gG fuses 10A or a miniature circuit‑breaker type C 6A when prospective short‑circuit current is below 400A.

What mechanical and electrical endurance should be expected?

Typical mechanical and electrical life is around 500 operating cycles for both main and auxiliary contacts.
