Product details

Motor protection circuit breaker for panel integration

The 3RV2021-1FA10-ZW97 has a current lifecycle stage, meaning it remains in active Siemens production and distribution.

Minimum clearance around the device: 50 mm upward, 50 mm downward, and 30 mm to the side — no clearance needed forward or backward. The main circuit terminals are M4 screws, and the terminal capacity is 2 × (1 to 2.5 mm²) or 2 × (2.5 to 10 mm²) solid or stranded.

Duty cycle and switching capacity

Maximum switching frequency in AC-3 duty (motor starting) is 15 operations per hour. The rated operational voltage range is 20 to 690 V, covering most low-voltage motor circuits.

Frequently asked questions
