Siemens 3VA2010-8JP46-0AA0

The 3VA20 circuit breaker, designed for low voltage applications, includes a sophisticated electronic trip unit (ETU550) with an LCD display, enhancing its functionality for line protection. With a rated permanent current (Iu) of 100A and an exceptional breaking capacity classified as Class L, this device can handle short-circuit currents up to 150kA at 415V and 24kA at 690V, ensuring reliable operation under high-stress conditions.

Measuring 5.5 x 7.1 x 4.2 inches (W x H x D), the breaker is suitable for installation on a DIN rail and features a frame clamp connection for the main circuit. The overload protection is adjustable, ranging from 40A to 100A, and the short-circuit protection offers settings from 0.6 to 10 times the nominal current (In) for enhanced safety measures. Notably, the device does not include integrated earth fault protection or an under-voltage release, focusing instead on robust short-circuit management.

This model is characterized by its durable design, with a degree of protection rated at IP40, making it suitable for various industrial environments.
