Siemens 3VA2040-6HL46-0AA0

The 3VA20 model is a low voltage molded case circuit breaker designed for efficient circuit protection. With a rated current of 40A and a high breaking capacity of 85kA at 415V, it ensures reliable operation in demanding conditions. This device adheres to IEC standards and is equipped with an electronic trip unit (ETU320), providing advanced overload and short-circuit protection.

Measuring 5.5 x 7.1 x 4.2 inches, the circuit breaker is designed for easy installation with a clamp connection on the front side, allowing it to be mounted on a DIN rail. The unit supports a wide adjustment range for short-circuit release, accommodating settings from 1.5 to 12 times the rated current. It is constructed with an IP40 degree of protection, making it suitable for various industrial applications.

Notably, the 3VA20 incorporates features such as a steel wrap-around lug for secure connections, although it does not include integrated earth fault or under voltage protection. Its design supports effective line protection while maintaining compact dimensions for space-constrained installations.
