Schneider Electric ZB4BZ1035 2NO Contact Block

Product Description

The SCHNEIDER ELECTRIC ZB4BZ1035 is a 2NO (normally open) electrical switch contact block designed for use in industrial control and automation applications. This contact block serves as the switching element within a modular pushbutton or selector switch assembly, completing or interrupting control circuits when the operator head is actuated. It is rated and certified to multiple international standards, making it suitable for demanding industrial environments. Licensed electricians and industrial maintenance technicians are the primary installers of this component.

This contact block is used in control panel assemblies across residential, commercial, and industrial installations where reliable operator interface switching is required. It is commonly mounted behind pushbutton heads, selector switches, or emergency stop operators on machine control panels and distribution boards. The 2NO contact configuration allows two independent normally open circuits to be controlled simultaneously from a single operator action.
