The 3VL2706-2UL33-0AA0 is a high-performance circuit breaker from Siemens, designed for line protection in electrical systems. It is a 3-pole circuit breaker, suitable for AC systems with a voltage of 415V. This model boasts a high breaking capacity (Icu) of 70kA, ensuring reliable protection against short circuits and overloads. The circuit breaker is equipped with an Electronic Trip Unit LCD ETU42, providing advanced protection features. The ETU42 offers LSIG protection functions, including overload protection (L), short-circuit protection (S), instantaneous protection (I), and ground fault protection (G). The rated current (In) is 63A, with an adjustable overload protection range (IR) from 25A to 63A. The short-circuit protection (ISD) can be set from 1.5 to 10 times the IR value, while the instantaneous protection (II) is fixed at 11 times the In value. This circuit breaker does not include an auxiliary release or auxiliary/alarm switch. It is designed for 3-phase/3-line systems.
