The ABB VM210 is a measuring and monitoring module designed to work with ABB electronic trip units such as the PR223DS and PR223EF installed in low‑voltage circuit breakers (for example in the T4, T5, and T6 range). It’s used to acquire voltage measurements from the electrical network and send scaled signals to the protection trip unit. The VM210 enhances the breaker’s ability to measure electrical parameters, enabling more precise protection and diagnostics.
