Schneider Electric ZB5AZ104 Contact Block 2NC XB5

Product Description

The SCHNEIDER ELECTRIC ZB5AZ104 is a 2NC (normally closed) contact block designed for use with XB5 series pushbutton and selector switch assemblies. It provides the electrical switching interface between a control device operator and the downstream circuit. The block supports multiple amperage ratings depending on the supply voltage, ranging from 0.10 amps at 600 VDC up to 6 amps at 120 VAC. Electricians and control panel technicians install this component when building or servicing industrial control stations, machine panels, and process equipment enclosures.

This contact block is intended for low-voltage control circuit applications in both light industrial and commercial settings. It mounts directly to XB5 series operator heads, making it a practical replacement or expansion component during panel assembly, retrofit work, or field repair. Its multi-standard certifications make it suitable for installations across North American and international jurisdictions.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the NEC and applicable local codes. De-energize and lock out the control panel before removing or installing any contact block. Verify that the selected amperage rating is appropriate for the circuit voltage before completing the connection. Do not exceed the rated amperage for the operating voltage of the circuit.
