Schneider Electric ZBE203 Contact Block

ZBE203 is a double contact block designed for the Harmony XB4 22 mm pushbutton family, providing two normally open contacts (DPST-NO) to extend a single operator head into two switched circuits. The block uses silver alloy contacts and offers screw clamp terminals for secure wiring, with front fixing compatible for 22 mm XB4 heads and support for multiple connection options (screw clamp, connector, Faston, or spring terminals) to suit different installations. Rated for up to 6 A at 120 VAC and 550 mA at 125 VDC, it is well suited for control-circuit applications such as interlocking, signaling, and load switching within industrial automation panels. This accessory is intended to be mounted directly on Harmony XB4 hardware, enabling expanded contact functionality while maintaining Schneider Electric’s anti-loosening screw-clamp connection system for reliable performance over time.
