Schneider Electric ZB4BZ103 Contact Block
The Schneider Electric ZB4BZ103 is a 22 mm contact block designed for industrial control panels. It provides two normally open contacts rated at 10 A and 600 V AC for momentary switching applications. The block suits engineers building or maintaining machinery that uses standard chrome metal operators.
Verify operator compatibility and wiring method
Confirm the panel cut-out matches the 22 mm mounting size and that the operator is a compatible ZB4 chrome metal type. The terminal connection uses screw clamps, so prepare for that wiring style. Check that the application requires momentary action rather than maintained contact.
Integrates with ZB4 metal operator stations
The block mounts behind a ZB4 chrome operator to complete a push-button or selector switch assembly. It meets CSA C22.2 No. 14, IEC 60947 series and UL 508 standards for control-circuit reliability. The compact body frees space inside crowded enclosures while delivering A600/Q600 rated performance.

Questions about this item
What comes with the ZB4BZ103 contact block and what must I buy separately?
The block itself is supplied; you must purchase a compatible 22 mm chrome operator such as a push-button or selector head separately.
How do I choose between the available versions of this block?
This model is a single 2NO momentary version rated 10A at 600V AC with screw-clamp terminals; other contact forms or actions would be different part numbers.
What does the 10A 600V AC rating mean when the block is installed in a control panel?
It indicates the block can switch up to 10 amperes at 600 volts AC in an A600/Q600 duty category when mounted on a suitable 22 mm operator.
