3VL3725-3SE36-0AA0 SIEMENS

The 3VL3725-3SE36-0AA0 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 VL250L series, known for its very high breaking capacity. It boasts an Icu of 100kA at 415V AC, ensuring reliable protection against short circuits and overloads. The integrated Electronic Trip Unit ETU20 provides advanced protection features, including adjustable overload (IR) and short-circuit (ISD, II) settings. The rated current (In) is 250A, with an adjustable overload protection range (IR) from 100A to 250A. The short-circuit protection (ISD) can be set from 1.5 to 10 times the IR value, while the instantaneous short-circuit protection (II) is fixed at 11 times the In value. This model does not include an auxiliary release or auxiliary/alarm switch, focusing on core circuit protection functionality. Its robust design and advanced features make it suitable for demanding environments where reliable and precise circuit protection is crucial. The ETU20 trip unit allows for fine-tuning of protection parameters to match specific load requirements, enhancing system safety and minimizing downtime. This circuit breaker provides a comprehensive solution for protecting electrical systems against overloads and short circuits.
