What the Description Tells You
The description — ABB A16-80-00-84 A16 8P CONTR 110/5 — identifies an 8-pole contactor with a 110 V / 5 VA control coil. The A16 series is a compact, modular contactor line used for switching motor loads and resistive loads in control panels. The 8-pole variant is less common than the 4-pole; it suits applications needing multiple isolated contact sets in a single device, such as reversing starters or multi-speed motor switching.
