It features a flush-style, round black metal pushbutton head with a 22 mm mounting hole diameter, fitting standard 22 mm panel cutouts. The maintained (MA) operation type means the switch holds its actuated state until pressed again, making it suitable for on\/off control functions where a latching output is required. Licensed electricians and control panel builders install this component during panel assembly or field service. It carries a NEMA 4X and NEMA 13 rating, confirming resistance to dust, oil, and water ingress in demanding environments.\u003c\/p\u003e\u003cp\u003eThe ZB4BH02 is used in industrial and commercial control panels where a reliable, panel-mount maintained pushbutton is needed. Typical applications include machine control stations, motor starter panels, and process control enclosures in manufacturing, utilities, and heavy industry. The 22 mm mounting format is a widely adopted standard in industrial controls, making this switch a common specification in new panel builds and retrofit service work. Its metal construction suits environments where plastic actuators would be vulnerable to mechanical damage or chemical exposure.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMaintained (MA) operation holds switch state after each actuation for on\/off control functions\u003c\/li\u003e\n\u003cli\u003e22 mm mounting hole diameter fits standard industrial panel cutouts\u003c\/li\u003e\n\u003cli\u003eFlush-style round black metal pushbutton head for durability in harsh environments\u003c\/li\u003e\n\u003cli\u003eNEMA 4X and NEMA 13 rated for resistance to dust, oil, and water ingress\u003c\/li\u003e\n\u003cli\u003eMeets multiple international standards including UL 508, CSA C22.2 No. 14, EN\/IEC 60947-5-1, and others\u003c\/li\u003e\n\u003cli\u003eCompact form factor suitable for dense panel layouts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style maintained push-button switch for 22 mm standard industrial control panel cutouts in commercial and industrial applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with applicable NEC requirements and local codes. De-energize and lock out the control panel before removing or installing any push-button components. A standard panel punch or existing 22 mm cutout is required for mounting. Verify the switch operation type and circuit logic before restoring power to the panel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hole Diameter\u003c\/strong\u003e: 22 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Maintained (MA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePush Button Style\u003c\/strong\u003e: Flush\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePush Button Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePush Button Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePush Button Material\u003c\/strong\u003e: Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNEMA Rating\u003c\/strong\u003e: 4X, 13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: UL Listed, UL 508, CSA, CSA C22.2 No. 14, EN\/IEC 60947-1, EN\/IEC 60947-5-1, EN\/IEC 60947-5-4, EN\/IEC 60947-5-5, Bureau Veritas, DNV, GL, JIS C 4520, LROS, RINA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SCHNEIDER ELECTRIC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZB4BH02\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51541002289458,"sku":"ZB4BH02","price":31.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8562dc141b93c130e386d7ea1ecc09f6.jpg?v=1785867215","url":"https:\/\/voomisupply.com\/products\/schneider-electric-zb4bh02-maintained-push-button-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
