The Siemens 3RV2032-4JA10 is a SIRIUS 3RV2 motor starter protector (circuit breaker for motor protection) in size S2, with a thermal overload release adjustable from 54 … 65 A and a magnetic short-circuit release at 845 A. Per Siemens it suits motors of about 30 kW at 400 V and has a rated short-circuit breaking capacity (Icu) of 100 kA at 400 V.<\/p>\n
Siemens describes this unit as: Circuit breaker size S2 for motor protection, CLASS 10 A-release 54…65 A N- release 845 A screw terminal increased switching capacity. Its instantaneous release at 845 A is set well above the motor starting current, so normal starts do not trip it.<\/p>\n
