Industrial push button for control panels

The Schneider Electric ZB4BH04 is a 22 mm flush push button operator designed for industrial electrical controls and automation. Its metal construction covers the head, bezel and basic material for durability in demanding environments. The red colour provides clear visual identification on control panels. It carries NEMA ratings 1, 2, 3, 4, 4X and 13 alongside IP66 ingress protection.

Suited for maintained switching in harsh settings

This operator uses a maintained action, so it stays in the pressed position until pressed again, making it suitable for on-off control functions. The wide range of NEMA and IP ratings means it withstands dust, water jets and corrosion in indoor or outdoor installations. Buyers who need a momentary push button that returns automatically should look at a different operator type. Applications requiring a different mounting diameter or a non-metal housing are not served by this model.

Compliant with multiple international standards

The device meets standards including IEC 60947-1, IEC 60947-5-1, IEC 60947-5-4, IEC 60947-5-5, IEC 60529, IEC 60068-2-6, IEC 60068-2-27, IEC 50102, IEC 60536, CSA C22.2 No. 14, UL 508, JIS C8201-1, JIS C8201-5-1, DNV, GL, LROS and Bureau Veritas. It is also RoHS compliant and REACH free of SVHC. These certifications simplify specification for projects that require documented conformity across different regulatory regimes. No legend plate is included, so separate labelling must be sourced if needed.

Questions about this item

Does this 22 mm operator need a separate contact block to complete the circuit?

Yes, the flush push button is an operator only and requires a compatible contact block mounted behind the panel to make or break the circuit.

Will the metal bezel and head survive the same NEMA 4X wash-down environment as my older 22 mm stations?

The operator carries NEMA 1, 2, 3, 4, 4X and 13 ratings plus IP66, so it matches or exceeds common legacy 22 mm panel cut-outs in wash-down duty.

How can I verify the maintained action is latched correctly after wiring?

Press the red flush head — it should stay in the depressed position until pressed again, confirming the maintained mechanism is functioning.
