ABB CV2-A011AA1 Under Voltage Relay

ABB CV2-A011AA1 Under Voltage Relay is a compact undervoltage protection relay in ABB’s CV2 family, designed to monitor supply voltage and switch contacts to protect connected equipment. The CV2 family offers voltage-relays in multiple coil variants and contact configurations; for example, CV2DJ is a 30 VDC coil version with two normally open contacts, and CV2D2J is a 24 VDC coil variant with four normally open contacts. Used in protection schemes across electrical distribution and motor-control applications, these relays provide fast undervoltage sensing and simple, mechanical contact outputs for signaling or interlocking. For exact coil voltage, contact arrangement, and timing characteristics of the CV2-A011AA1, consult ABB’s official CV2 product documentation or the model’s datasheet.
