ABB 1SVR740830R0400 Control

Description

• The ABB 1SVR740830R0400 CM-ESS.2P, a single-functional voltage monitoring relay designed for excellence within the CM single-phase monitors range. This relay operates seamlessly with a rated control supply voltage spanning 24 to 240 V AC / DC, setting a new standard for reliability in voltage monitoring applications.

• Featuring a 2 c/o (SPDT) output with contacts rated at 250 V / 4 A, the CM-ESS.2P excels with an RMS measuring principle for both DC and AC voltages. Its versatility is showcased through four measuring ranges: 3-30 V, 6-60 V, 30-300 V, and 60-600 V, ensuring compatibility with a wide spectrum of voltage monitoring needs. Operating according to the open-circuit principle, the CM-ESS.2P is configurable for both over- and undervoltage monitoring.
