The 3VL2710-2UL33-0AA0 is a high-performance circuit breaker from Siemens, designed for line protection in industrial and commercial applications. This 3-pole circuit breaker is part of the VL160H series, known for its high breaking capacity of Icu=70kA at 415V AC. It features an Electronic Trip Unit LCD ETU42, providing advanced protection and monitoring capabilities. The ETU42 offers LSIG protection functions, including overload (L), short-circuit (S), instantaneous (I), and ground fault (G) protection. The rated current (In) is 100A, with an adjustable overload protection range (IR) from 40 to 100A. 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 is designed for 3-phase/3-line systems and does not include an auxiliary release or auxiliary/alarm switch. Its robust design and comprehensive protection features ensure reliable performance and enhanced safety for electrical systems. The LCD display provides clear and accessible information for monitoring and adjusting protection settings.
