The Siemens 3RV24314BA10 is a size S2 circuit breaker from the SIRIUS 3RV2 series, specifically designed for transformer protection applications. It features a thermal magnetic overload release with an adjustable current response value ranging from 14 to 20 Amps.
This circuit breaker operates with a rated voltage of up to 690V AC and has a rated operational current of 20A at 400V AC (AC-3 and AC-3e). It provides a breaking capacity (Icu) of up to 65 kA at 400V AC and an operating short-circuit current capacity (Ics) of up to 30 kA at 400V AC. The device includes phase failure detection and has a trip class of CLASS 10.
Designed for DIN rail mounting, the 3RV24314BA10 has a rotary actuator and screw terminals for main circuit connections. It supports auxiliary switch extensions. The operating temperature range is -20 to +60 °C, and it is built to withstand mechanical and electrical stresses with typical service lives of 50,000 switching cycles for both main and auxiliary contacts.
Key technical data includes a power loss of 14.5W at rated current in hot operating state, insulation voltage of 690V, and surge voltage resistance of 6 kV. The breaker also meets UL/CSA ratings for full-load current at 480V and 600V.
