3VA2163-8HM46-0AA0 SIEMENS

The 3VA2163-8HM46-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for comprehensive line protection in industrial and commercial applications. This IEC frame 160 circuit breaker boasts a high breaking capacity class L, with an ultimate short-circuit breaking capacity (Icu) of 150kA at 415V, ensuring reliable performance under fault conditions. Equipped with an ETU330 electronic trip unit, it offers precise and adjustable protection characteristics. The overload protection (Ir) can be set from 25A to 63A, while the short-circuit protection (Ii) ranges from 1.5 to 12 times the rated current (In). The rated current (In) of the breaker is 63A. Furthermore, it includes adjustable N conductor protection, allowing settings of OFF or 100%, providing flexibility in neutral management. Ground-fault protection (Ig) is also adjustable from 0.25 to 1 times In, with a time delay (tg) of 0.1/0.3s for selective coordination. The breaker utilizes clamp connections for secure and easy installation. This model provides advanced protection features and reliable performance for demanding electrical systems.
