Motor protection circuit breaker, 2.5 A, Trip Class 10
The Siemens 3RV1021-1CA15-ZX95 is a SIRIUS motor protection circuit breaker rated for 2.5 A continuous current and 0.75 kW at 400 V AC-3 duty, with a Trip Class 10 thermal overload curve. It's designed for motor protection in control panels, with screw-type terminals for main and auxiliary circuits.
Breaking capacity reaches 100 kA at 240 V, 400 V, and 500 V AC, dropping to 8 kA at 690 V AC. The 8 kA at 690 V still covers most motor branch circuits at that voltage level.
This part carries a current production lifecycle status. The RoHS compliance date is 01.05.2012, meaning it meets the EU RoHS directive for substances of concern.
Main circuit terminals accept solid conductors 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²), or stranded 2x (1...2.5 mm²) and 2x (2.5...6 mm²). Auxiliary and control circuit terminals are also screw-type. The auxiliary switch is transverse design and field-installable.
Environmental and operational limits
Shock resistance is 25 g for 11 ms. The unit has phase failure detection but no ground fault detection. Power dissipation in hot operating state is 7.25 W at rated current.
