ZBE101 is Schneider Electric's Harmony 22 mm push-button add-on contact block that delivers a single normally open (NO) contact for low-power control circuits. It is designed to mount behind Harmony XB4 metal and XB5 plastic 22 mm push-button ranges and uses screw-clamp terminals for secure wiring, with additional terminal styles available on compatible variants. The contact materials include silver alloy (Ag/Ni) and gold-flashed variants (Ag/Ni/Au) to suit different switching characteristics. In Schneider's XB4/XB5 add-on contact block lineup, ZBE101 corresponds to 1 NO, while ZBE102 provides 1 NC, and additional ZBE options exist for specialized applications.
