Schneider Electric ZB4BZ141 Switch Contact Block No 2NC

Product Description

The SCHNEIDER ELECTRIC ZB4BZ141 is an electrical switch contact block designed for use in industrial control circuits. It features a NO/2NC contact configuration, allowing one normally open and two normally closed switching paths in a single compact unit. The block supports multiple amperage ratings across a range of AC and DC voltages, from 0.10 amps at 600 VDC up to 6 amps at 120 VAC, making it adaptable to a wide variety of control panel applications. Licensed electricians and industrial controls technicians typically install this component as part of pushbutton station assemblies or selector switch setups on control enclosures and machine panels.

This contact block is suited for commercial and industrial installations where panel-mount control devices require reliable switching contacts. It is commonly used in motor control centers, machine control panels, and process equipment enclosures. The compact form factor and multi-standard certifications make it appropriate for both domestic and international electrical projects. Typical applications include start/stop pushbutton stations, emergency stop assemblies, and selector switch control circuits.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and any applicable local codes. De-energize and lock out the control panel before installing or replacing contact blocks. Verify that the amperage and voltage rating of the contact block matches the circuit requirements before connecting. Do not exceed the rated current for the corresponding voltage level listed in the specifications.
