The Siemens 3RV24214DA20 is a size S0 circuit breaker from the SIRIUS 3RV2 series, specifically designed for transformer protection applications. This thermal magnetic breaker offers a rated current of 25A and supports a wide operating voltage range from 20V to 690V.
Key electrical specifications include a 3-pole configuration, adjustable overload release from 18A to 25A, and an instantaneous trip unit response value of 400A. It provides a maximum breaking capacity (Icu) of 100 kA at 240V and 55 kA at 400V. The breaker operates with a frequency of 50/60 Hz and has a power loss of 10.5W at AC in hot operating state.
Designed for mechanical robustness, it features a mechanical service life of 100,000 switching cycles for both main and auxiliary contacts, and an electrical endurance of 100,000 cycles. The operating ambient temperature range is -20°C to +60°C. Mounting is facilitated via a standard DIN rail.
This circuit breaker also includes phase failure detection and is rated with trip class 10. It is suitable for applications requiring standard switching capacity and is built to withstand shock resistance of 25g / 11 ms.
