The operating voltage range of 200 to 500 V covers common low-voltage networks without needing a separate transformer tap. Mounting is by screw fixing, not DIN-rail snap-on, so plan for panel-mount hardware. The main current circuit connects via busbar connection, while the auxiliary and control circuit uses screw-type terminals — a common arrangement for panel builders wiring in a control cabinet. Because the part is current, there is no official successor to track. ## Thermal and environmental limits During operation, the ambient temperature limit is 55 °C, with derating beginning at 40 °C. That means full rated current is available up to 40 °C; above that, the output must be reduced per the thermal curve — a critical detail for panel builders placing this inside a sealed enclosure near other heat sources. The control supply voltage is AC only, at 50 or 60 Hz. No DC control option is listed, so the control transformer must supply AC at the same frequency as the line. ## Auxiliary contacts and protection The auxiliary contact block provides 2 NO contacts and 1 CO contact, with no NC contacts. This is enough for a run-status signal and a fault indication, but if you need a separate NC for a safety circuit, you will need an external auxiliary contact block. Note that this soft starter does not include integrated motor overload protection or thermistor motor protection evaluation. Overload protection must be provided externally — typically by a separate motor-protective circuit breaker or overload relay in the line.","metaTitle":"Siemens 3RW2225-1AB15-ZA02 SIRIUS Soft Starter, 22 A","metaDescription":"Siemens SIRIUS 3RW2225-1AB15-ZA02 soft starter for high feature applications.
