3VL5763-1UM36-0AA0 SIEMENS

The 3VL5763-1UM36-0AA0 is a robust and reliable circuit breaker manufactured by Siemens, designed for comprehensive line protection in industrial and commercial applications. This 3-pole circuit breaker is engineered to handle a rated current of 630A, making it suitable for high-power electrical systems. It features a standard breaking capacity (Icu) of 55kA at 415V AC, ensuring effective protection against short circuits and overloads. The integrated LCD ETU42 trip unit offers advanced protection functionalities, including LSIG (Long-time, Short-time, Instantaneous, Ground fault) settings, configurable for 3 phases/4 lines. The overload protection (IR) can be adjusted from 252A to 630A, providing flexibility to match specific load requirements. The short-circuit protection (ISD) ranges from 1.5 to 9 times the IR setting, while the instantaneous protection (II) is set at 10 times the rated current (IN). This circuit breaker comes without auxiliary release and auxiliary/alarm switch. A connecting cable is included for ease of installation and integration into existing electrical systems. Its precise and adjustable protection settings, coupled with its high breaking capacity, make it an ideal choice for safeguarding critical electrical infrastructure.
