Product Details
Schneider Electric XB7NS8444 - This Harmony XB7, emergency stop / shutdown 40mm mushroom head monolithic red push button operates with a latched turn to release mechanism and uses screw-clamp terminals. This emergency stop / shutdown button, also called EMS (Emergency Machine Stop) and EMO (Emergency Off) is easily installed into a standard 22mm diameter cut-outs and connected with simple screw-clamp connections. It is clearly distinguishable visually at a distance thanks to a clear color and a prominent 40mm mushroom shape. It is impact resistant, dust resistant, water resistant and vibration resistant thanks to its IP65, making it ideal for operation in harsh environments. It has a double insulated plastic bezel. Its wide range of operating temperatures from -40ðC to 70ðC allows versatility in usage of product. Electrihub represents a commitment to excellence, delivering world-class electrical products with precision, quality, and trust across global markets.

Schneider Electric XB7NS8444 is a monolithic 22.5 mm plastic push button / pilot device (Harmony XB7 series) integrating the operator head, mounting collar, and electrical contact block into a single compact body. It is rated for operational voltages up to 240V/415V AC (50 Hz) with a 4A to 10A thermal current rating compliant with IS/IEC 60947-5-1.
Because of its monolithic all-in-one design, XB7NS8444 eliminates the need to order separate collars and contact blocks, significantly reducing assembly labor, panel mounting depth (under 54 mm), and total bill-of-materials costs in Indian OEM machinery and distribution panels.
Featuring a front bezel sealing ring, XB7NS8444 achieves IP65 (front face) and IP20 (rear terminals) ingress protection compliant with IS/IEC 60529, operating reliably under continuous machine vibration (5 gn, 2-500 Hz per IEC 60068-2-6) and ambient temperatures up to +70°C.
The unit features captive screw-clamp terminals with self-lifting pressure plates accepting solid or stranded conductors from 0.34 mm² to 2.5 mm² (22-14 AWG), preventing loose wire strands and high contact resistance in Indian industrial control panels.
Order original Schneider Electric XB7NS8444 push buttons on Electrihub India. Electrihub India provides guaranteed authentic components, GST tax invoices for ITC savings, and fast courier dispatch across all Indian states.
The Schneider Electric XB7NS8444 belongs to the Harmony XB2/XB4/XB5/XB6/XB7 22 mm modular pushbutton range, and it installs into a 22 mm (22.5 mm nominal) round panel cutout conforming to EN/IEC 60947-1, the same footprint used across the whole Harmony platform for easy retrofit. Checking this cutout size before ordering avoids rework on an already-drilled control panel, and because the dimension follows an internationally recognised standard, panels designed in one country can be fitted with the XB7NS8444 sourced from another without modifying the enclosure.
The Schneider Electric XB7NS8444 is rated at IP66, IP67, IP69K and (on the metal XB4 range) up to IP69K wash-down protection, making it dust-tight and resistant to high-pressure and high-temperature jet cleaning. This level of sealing is what determines whether the device can be specified for washdown areas, outdoor enclosures, dusty workshops or humid coastal sites, so it is one of the first specifications engineers in any country check when matching a pushbutton to its installation environment.
The Schneider Electric XB7NS8444 is manufactured to EN/IEC 60947-1 and EN/IEC 60947-5-1, EN/IEC 60947-5-4, CSA C22.2 No. 14, UL 508 and JIS C4520, so it can be legally specified on panels built to European, North American, Canadian and Japanese electrical codes. Holding recognised IEC, UL, CSA and CE approvals together (rather than just one regional mark) is what lets the same part number be specified on machinery and switchgear panels built for the EU, North America, the Middle East, Africa and Asia-Pacific, without needing a region-specific substitute.
The Schneider Electric XB7NS8444 offers a rated insulation voltage of up to 600 V (metal XB4 range) or 250 V (plastic/compact ranges), with a rated operational current of roughly 0.1–6 A depending on the AC-15/DC-13 contact block fitted (commonly 1 NO, 1 NC, 1 NO+1 NC or 2 NO). Confirming the rated voltage, current and contact configuration against the control circuit it will switch is essential, since undersizing the contact block against the connected load is one of the most common causes of premature pushbutton failure in the field.
The Schneider Electric XB7NS8444 is rated for an ambient operating range of -25°C to +70°C, with an electrical/mechanical durability of several hundred thousand to over a million operations, and an 18-month manufacturer warranty on the complete unit. This combination of climate range and cycle life is what allows the same push button to be deployed in cold-storage plants, standard factory floors and hot, humid outdoor installations across different climate zones without a separate temperature-rated variant.

Had a switch failure on an imported packaging line and local distributors were quoting a 3-week lead time. Electrihub had the exact Schneider XB7NS8444 in stock and shipped it out immediately. Machine was operational in no time. Outstanding support.
Procured 20 units of Schneider XB7NS8444 for a retrofitting project. Electrihub India offered far better rates than local market distributors. Invoicing with company GST was seamless and packing was sturdy.
Had an emergency breakdown on our conveyor line due to a damaged button. Ordered the Schneider XB7NS8444 on Electrihub India and it reached us within 48 hours. Plug-and-play replacement, machine was back up in no time. Great service.
