It features a round, extended straight-profile green metal button with no illumination. The momentary (MO) operation type means the switch activates only while held and returns to its default state upon release. Rated NEMA 4X and 13, this switch is built to resist dust, oil, and corrosive environments. It meets a broad set of international standards including UL 508, EN\/IEC 60947-5-1, CSA C22.2 No. 14, and JIS C 4520, making it suitable for both domestic and export equipment builds. Electricians and controls technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis push-button switch is used in industrial and commercial control panels, machine operator stations, and automation equipment where a momentary contact input is required. The 22 mm mounting hole diameter is a widely adopted standard in panel-mount hardware, fitting standard 22 mm cutouts found in enclosures and operator interface stations across a wide range of industries including manufacturing, process control, and marine applications. The green color convention typically designates start or safe-condition functions in panel wiring layouts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e22 mm mounting hole diameter fits standard panel cutouts\u003c\/li\u003e\n  \u003cli\u003eMomentary (MO) operation — activates on press, returns on release\u003c\/li\u003e\n  \u003cli\u003eRound, extended straight-profile green metal button — nonilluminated\u003c\/li\u003e\n  \u003cli\u003eNEMA 4X and 13 rated for oil-tight and corrosion-resistant service\u003c\/li\u003e\n  \u003cli\u003eCertified to UL 508, CSA C22.2 No. 14, EN\/IEC 60947-5-1, JIS C 4520, DNV, GL, RINA, LROS, and Bureau Veritas\u003c\/li\u003e\n  \u003cli\u003eMetal push-button construction for durability in industrial environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for 22 mm push-button switch assemblies used in industrial control panels and operator stations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed electrician or qualified controls technician. De-energize the control panel and lock out or tag out all power sources before beginning work, in accordance with NFPA 70E and applicable local codes. The switch mounts through a 22 mm panel cutout and is secured from the rear with the included hardware. Verify contact block compatibility and torque all terminal connections to the contact block manufacturer specifications before restoring power.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: Momentary (MO)\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 Profile\u003c\/strong\u003e: Extended (Straight)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePush Button Color\u003c\/strong\u003e: Green\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePush Button Material\u003c\/strong\u003e: Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperator Illumination\u003c\/strong\u003e: Non-Illuminated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNEMA Rating\u003c\/strong\u003e: 4X, 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions (H x W x L)\u003c\/strong\u003e: 1.3 inches x 1.3 inches x 1.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: UL 508, UL Listed, CSA C22.2 No. 14, EN\/IEC 60947-1, EN\/IEC 60947-5-1, EN\/IEC 60947-5-4, EN\/IEC 60947-5-5, JIS C 4520, Bureau Veritas, DNV, GL, RINA, LROS\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: ZB4BL3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51543861788978,"sku":"ZB4BL3","price":22.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/467121734007f446e83c8f87a8fd1224.jpg?v=1785922143","url":"https:\/\/voomisupply.com\/products\/schneider-electric-zb4bl3-push-button-switch-22mm-green","provider":"Voomi Supply","version":"1.0","type":"link"}
