The Eaton XTRM10A40T is a four-pole relay with four normally open contacts and zero normally closed contacts, powered by a 24‑volt AC coil. When the coil energizes, all four NO contacts close to connect their respective circuits, enabling a single actuation to switch four lines at once. This 24 VAC relay is suitable for control‑panel wiring and automation tasks where four separate loads need to be controlled from a single device. The part number XTRM10A40T identifies this exact configuration in Eaton’s XTRM series.
