Product Description

Lifecycle Status:

The 3VA20 molded case circuit breaker is designed for low voltage applications and integrates an electronic trip unit, specifically the ETU860, which offers comprehensive line protection and metering capabilities. With a rated current of 40A and a 4-pole configuration, this device ensures reliable operation in various industrial settings.

Its exceptional breaking capacity of 110kA at 415V and 2kA at 690V (Icu) signifies its ability to safeguard circuits against overcurrents. The circuit breaker features a Class C breaking capacity, which is essential for applications requiring high fault current withstand. Additionally, the overload protection settings can be adjusted between 16A and 40A, while the short-circuit protection can be customized with settings ranging from 0.6 to 10 times the rated current.

Furthermore, this model includes integrated earth fault protection and is equipped with a switched-off indicator. The device is suitable for DIN rail mounting, ensuring easy installation in control panels and cabinets. With dimensions of 5.5 x 7.1 x 4.2 inches, it is compact yet powerful enough to deliver robust performance in demanding environments.
