Schneider Electric ZB4BZ1025 Nc Switch Contact Block

Product Description

The SCHNEIDER ELECTRIC ZB4BZ1025 is a normally closed (NC) electrical switch contact block designed for use in industrial control and automation applications. It serves as the switching element in pushbutton and selector switch assemblies, making or breaking a control circuit when the operator actuates the head. The contact block weighs 0.11 pounds and measures 1.5 inches in length, 1.2 inches in width, and 1.9 inches in height. Licensed electricians and industrial maintenance technicians typically install this component as part of a larger operator interface or machine control panel build.

This contact block is suited for light industrial and commercial control panel applications where a reliable NC contact configuration is required. It is commonly installed behind operator heads on machine control stations, motor control centers, and pendant stations. Its compact footprint accommodates standard 22mm pushbutton assemblies and fits within space-constrained enclosures. The ZB4BZ1025 meets a broad set of international standards, making it appropriate for domestic and export-market installations alike.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC requirements and local codes. De-energize and lock out the control panel before removing or installing any contact block. Verify the contact configuration (NC) matches the circuit design before completing the assembly. Do not exceed the voltage and amperage ratings marked on the contact block body or detailed in the product datasheet.
