The Siemens 3RV27111DD10 is a thermal magnetic circuit breaker designed for system protection according to UL 489 and CSA C22.2 No. 5 standards. This S00 size breaker offers a 3.2A operational current and a rated operating voltage of up to 690V.
Key electrical specifications include a breaking capacity of 100 kA at 400V AC and a 42A instantaneous short-circuit trip unit response value. The breaker is equipped with screw terminals for main circuit connections and supports DIN rail mounting for easy installation.
With a mechanical service life of 100,000 switching cycles for both main and auxiliary contacts, and an electrical endurance also rated at 100,000 cycles, this circuit breaker is built for reliability. It operates within an ambient temperature range of -20 to +60 °C and is suitable for installation at altitudes up to 2000 meters.
The operating voltage range is 20 V to 690 V AC, with a rated frequency of 50/60 Hz.
The rated operational current is 3.2 A.
It has 3 poles for the main current circuit.
The ultimate breaking capacity (Icu) at 400V AC is 100 kA, and the operating breaking capacity (Ics) is also 100 kA.
The breaker can operate in ambient temperatures from -20°C to +60°C.
Yes, it supports a product extension auxiliary switch, but it does not include built-in auxiliary contacts (0 NC, 0 NO, 0 CO).
It holds CCC, CE, CSA, EAC, and UL approvals.
