3VL2706-2SP33-0AA0 SIEMENS

The 3VL2706-2SP33-0AA0 is a robust 3-pole circuit breaker from Siemens, designed for motor/generator protection. It is part of the VL160H series, known for its high breaking capacity, specifically Icu=70kA at 415V AC. This circuit breaker features an Electronic Trip Unit ETU10M, providing advanced protection and control capabilities. The ETU10M offers LI functionality, including adjustable overload protection with a rated current (IR) range of 25 to 63A. The instantaneous short-circuit protection (II) is adjustable from 1.25 to 11 times the rated current (IN). This allows for precise tailoring of protection settings to the specific application requirements. The circuit breaker is designed without an auxiliary release, simplifying the installation and operation. It also lacks auxiliary/alarm switches, focusing on core protection functionality. This model is well-suited for applications requiring reliable and adjustable circuit protection in motor and generator circuits.
