ABB 1SVR730830R0500 Control

Description

• The ABB 1SVR730830R0500 CM-ESS.MS, a multifunctional voltage monitoring relay that exemplifies versatility within the CM single-phase monitors range. Engineered to precision, this monitoring relay operates seamlessly with a rated control supply voltage ranging from 24 to 240 V AC / DC. With a 2 c/o (SPDT) output and contacts rated at 250 V / 4 A, it sets the standard for reliability in voltage monitoring applications.

• The CM-ESS.MS offers an expansive range of four measuring options: 3-30 V, 6-60 V, 30-300 V, and 60-600 V. This adaptability ensures compatibility with diverse voltage monitoring requirements. The CM-ESS.MS goes beyond conventional functionalities, providing users with the flexibility to choose between over- or undervoltage monitoring, open- or closed-circuit operating principles, and the option of a latching function.

• One of the standout features of the CM-ESS.MS is its adjustable hysteresis, allowing users to fine-tune it within a range of 3 to 30% of the threshold value, providing optimal stability in varied operational conditions. Additionally, users can exercise precise control over the relay's performance with adjustable tripping delay and start-up delay, ranging from instantaneous to 30 s (0, 0.1-30 s).
