Schneider Electric Telemecanique ZB2-BZ106 Contact Block

The Schneider Electric Telemecanique ZB2-BZ106 contact block is a 2-pole snap-action device in the Harmony XB2 family, configured as 1 normally open plus 1 normally closed contact for reliable control-circuit switching in industrial control panels, conveyors, and packaging lines. Designed for mounting on 22 mm Harmony XB2 operator heads, it uses screw clamp terminals for secure, field-serviceable electrical connections and supports high-cycle operation in demanding industrial environments. Electrical ratings include a rated insulation voltage of 600 V and a conventional thermal current of 10 A, enabling predictable performance with push buttons and selector switches in control circuits. Common applications span packaging machines, conveyor systems, motor control centers, and automated production equipment, where the ZB2-BZ106 is used for repair, retrofit, expansion, or replacement; common replacements include ZB2-BE101, ZB2-BE102, and ZBE102. Because it is part of the Harmony XB2 family, the ZB2-BZ106 is straightforward to retrofit in existing control panels that use 22 mm operator heads, aligning with common OEM practices in industrial automation.
