Commonly installed in motor control centers, HVAC systems, pumps, compressors, conveyors, and manufacturing equipment where dependable three-phase power monitoring is essential. Maintenance teams, OEMs, and system integrators use the B263 for replacement, repair, retrofit, and preventive maintenance to minimize equipment damage and reduce unplanned downtime. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"648\" data-end=\"665\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"666\" data-end=\"1256\"\u003eThe Time Mark B263 is a solid-state three-phase power monitor that continuously supervises Wye or Delta power systems without requiring a neutral connection and de-energizes its output relay whenever phase loss, phase reversal, or undervoltage conditions are detected. It is widely used in industrial automation systems, water and wastewater facilities, motor control panels, compressors, conveyors, HVAC equipment, and process machinery where reliable three-phase power monitoring helps prevent costly electrical failures and production interruptions. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1258\" data-end=\"1287\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1288\" data-end=\"2109\"\u003e• Manufacturer: Time Mark Corporation\u003cbr data-start=\"1325\" data-end=\"1328\"\u003e• Manufacturer Part Number (MPN): B263\u003cbr data-start=\"1366\" data-end=\"1369\"\u003e• Product Type: 3-Phase Power Monitor\u003cbr data-start=\"1406\" data-end=\"1409\"\u003e• Nominal Voltage: 208\/240 VAC (Phase-to-Phase)\u003cbr data-start=\"1456\" data-end=\"1459\"\u003e• Voltage Adjustment Range: 160–240 VAC\u003cbr data-start=\"1498\" data-end=\"1501\"\u003e• Frequency: 60 Hz\u003cbr data-start=\"1519\" data-end=\"1522\"\u003e• Power Consumption: 1.5 W\u003cbr data-start=\"1548\" data-end=\"1551\"\u003e• Monitoring Functions: Phase Loss, Phase Reversal, Undervoltage\u003cbr data-start=\"1615\" data-end=\"1618\" data-is-only-node=\"\"\u003e• Output Contacts: SPDT, 10 A at 240 VAC Resistive\u003cbr data-start=\"1668\" data-end=\"1671\"\u003e• Response Time: 50 ms\u003cbr data-start=\"1693\" data-end=\"1696\"\u003e• Reset Type: Automatic\u003cbr data-start=\"1719\" data-end=\"1722\"\u003e• Repeat Accuracy: ±0.1% of Set Point\u003cbr data-start=\"1759\" data-end=\"1762\"\u003e• Dead Band: Approximately 2%\u003cbr data-start=\"1791\" data-end=\"1794\"\u003e• Mounting: Surface Mount\u003cbr data-start=\"1819\" data-end=\"1822\"\u003e• Enclosure Material: ABS Plastic\u003cbr data-start=\"1855\" data-end=\"1858\"\u003e• Operating Temperature: -20°F to +131°F (-29°C to +55°C)\u003cbr data-start=\"1915\" data-end=\"1918\"\u003e• Certifications: UL Recognized, CSA Certified\u003cbr data-start=\"1964\" data-end=\"1967\"\u003e• Application: Three-phase motor, compressor, pump, HVAC, conveyor, and industrial equipment protection. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"2111\" data-end=\"2135\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"2136\" data-end=\"2196\"\u003e• Time Mark B263M\u003cbr data-start=\"2153\" data-end=\"2156\"\u003e• Time Mark B263SG\u003c\/p\u003e","brand":"TIME","offers":[{"title":"New","offer_id":51714027946286,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_f4452976-9de3-47d8-993b-b0e788986979.jpg?v=1770414226","url":"https:\/\/plgautomation.com\/products\/time-mark-3-phase-208-240vac-power-monitor-b263","provider":"PLG Automation ","version":"1.0","type":"link"}
