Two-wire control provides both no-voltage drop-out protection, or low-voltage drop-out protection.

Two-wire Control

A control circuit configuration using two wires to connect the control element, typically for simple on/off operations.

No-voltage Drop-out

A feature in electrical control circuits that causes the device to trip or shut off when the supply voltage falls below a certain level, enhancing safety.

Low-voltage Drop-out

A protective feature in electrical devices that causes them to turn off when voltage levels fall below a specified threshold.
