3VA5170-6EF41-0AA0 SIEMENS

The 3VA5170-6EF41-0AA0 is a robust and reliable circuit breaker from Siemens' 3VA5 UL series, designed for optimal circuit protection. This 4-pole circuit breaker, part of Frame 125, is engineered to safeguard electrical systems with a high breaking capacity. Specifically, it boasts a breaking capacity class H, capable of interrupting fault currents up to 65kA at 480V. It is configured for line protection, utilizing a TM240 trip unit with an ATAM (Adjustable Thermal-Magnetic) function. The breaker's rated current (In) is 70A, with an adjustable overload protection range (Ir) from 56A to 70A. Furthermore, it provides short-circuit protection (Ii) adjustable between 5 to 10 times the rated current (In). This model features an unprotected neutral (N) conductor configuration, meaning it does not have a dedicated connection or protection for the neutral line. This circuit breaker is well-suited for industrial and commercial applications where reliable and adjustable circuit protection is essential. Its adjustable settings allow for fine-tuning to match specific load requirements, enhancing safety and preventing nuisance tripping.
