ABB E225-11B is a grey, non-illuminated push-button in ABB’s E225 family. It provides two contacts: 1 normally open (NO) and 1 normally closed (NC), enabling simple start/stop signaling in control circuits. It is rated for 16 A at 250 V AC and designed for installation in electrical panels where control signals are required in 250 V systems. ABB literature describes the E225 series as non-illuminated pushbuttons used for control and signaling in industrial panel assemblies.
