3VL3725-3ME36-0AA0 SIEMENS

The 3VL3725-3ME36-0AA0 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, ensuring reliable protection against overcurrents and short circuits. It boasts an impressive ultimate breaking capacity (Icu) of 100kA at 415V AC, making it suitable for demanding electrical environments. The breaker features an Electronic Trip Unit (ETU20), providing advanced protection and control capabilities. The ETU20 offers adjustable overload protection (IR) ranging from 100A to 250A, allowing for precise customization to match specific load requirements. It also includes short-circuit protection (ISD) with settings from 1.5 to 10 times the rated current (IR), and instantaneous short-circuit protection (II) set at 11 times the rated current (IN). This comprehensive protection scheme ensures the safety and reliability of electrical systems. The breaker is communication-capable via ETU, enabling remote monitoring and control for enhanced system management. Note that this model does not include an auxiliary release or alarm switch. This circuit breaker provides robust and adaptable protection for a wide range of electrical applications.
