The Siemens 3RV20210JA25 is a circuit breaker from the SIRIUS 3RV2 series, specifically designed for motor protection applications. It offers an adjustable current response value for overload protection ranging from 0.7 to 1 Ampere, with a fixed N-release of 13A. This breaker operates with a CLASS 10 trip class, ensuring reliable protection for motors.
Key electrical specifications include a rated operating voltage of up to 690V AC and a rated operational current of 1A at 400V AC (AC-3 and AC-3e). The breaker has a breaking capacity of 100 kA at 240V AC. It is equipped with 3 poles for the main current circuit and includes auxiliary switches with 1 normally open (NO) and 1 normally closed (NC) contact.
Environmental conditions for operation include an ambient temperature range of -20 to +60 °C and a relative humidity of 10 to 95%. The breaker is suitable for installation at altitudes up to 2000 meters. It features a DIN rail mounting type for easy integration into control panels. The mechanical and electrical endurance for both main and auxiliary contacts is typically 100,000 switching cycles.
