Product Description
The 3VA20 frame circuit breaker is designed for low voltage applications and complies with IEC standards. It incorporates an electronic trip unit, ETU850, that provides metering capabilities. The device has a very high breaking capacity classified as Class C, with a rated short-circuit breaking capacity (Icu) of 110kA at 415V and 2kA at 690V.
This circuit breaker operates at a rated voltage of 690V and a permanent current rating of 25A. It features a rocker lever as the control element and allows for adjustable overload protection ranging from 10A to 25A. The settings for short-circuit protection include 0.6 to 10 times the rated current for instantaneous protection and 1.5 to 12 times for delayed tripping.
It is suitable for DIN rail mounting and has a degree of protection rated at IP40. The device is constructed as a built-in unit using fixed installation techniques, and it includes a connection with a lug terminal and a nut keeper kit.
