Only when the power supply is turned off can the key can be rotated in the lock and withdrawn. While it is removed the power supply is isolated, ensuring that the machine cannot be restarted while the guard door is open. The key can then be used to release the machine guard, allowing access to the machinery. After the guard is closed it can be removed and inserted back into the original control unit, thus allowing the power supply to be activated again. Trapped key interlocks can withstand harsher environments than electrical interlocks and are often used in industrial settings where serious risk of injury can occur to machine operators.\u003c\/div\u003e\u003c\/div\u003e\u003cbr\u003e\u003cdiv class=\"sc-VigVT gBHNjZ\"\u003e\u003ch2 font-size=\"6\" data-testid=\"specifications-title\" class=\"sc-bdVaJa YmDnE\"\u003eSpecifications\u003c\/h2\u003e\u003c\/div\u003e\u003ctable data-testid=\"specification-attributes\" class=\"sc-jzJRlG dQhhps\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003ctd\u003eAttribute\u003c\/td\u003e\n\u003ctd\u003eValue\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd data-testid=\"specification-attributes-key\"\u003eLock Style\u003c\/td\u003e\n\u003ctd data-testid=\"specification-attributes-value\"\u003eKeyed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-testid=\"specification-attributes-key\"\u003eNormal State Configuration\u003c\/td\u003e\n\u003ctd data-testid=\"specification-attributes-value\"\u003e4NO\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-testid=\"specification-attributes-key\"\u003eLock Type\u003c\/td\u003e\n\u003ctd data-testid=\"specification-attributes-value\"\u003eInterlock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-testid=\"specification-attributes-key\"\u003eMaximum AC Voltage\u003c\/td\u003e\n\u003ctd data-testid=\"specification-attributes-value\"\u003e1000V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-testid=\"specification-attributes-key\"\u003eHousing Material\u003c\/td\u003e\n\u003ctd data-testid=\"specification-attributes-value\"\u003eStainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-testid=\"specification-attributes-key\"\u003eRange\u003c\/td\u003e\n\u003ctd data-testid=\"specification-attributes-value\"\u003eProsafe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-testid=\"specification-attributes-key\"\u003eIP Rating\u003c\/td\u003e\n\u003ctd data-testid=\"specification-attributes-value\"\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-testid=\"specification-attributes-key\"\u003eNumber of Head Directions\u003c\/td\u003e\n\u003ctd data-testid=\"specification-attributes-value\"\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-testid=\"specification-attributes-key\"\u003eSeries\u003c\/td\u003e\n\u003ctd data-testid=\"specification-attributes-value\"\u003e440T\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-testid=\"specification-attributes-key\"\u003eDepth\u003c\/td\u003e\n\u003ctd data-testid=\"specification-attributes-value\"\u003e64mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-testid=\"specification-attributes-key\"\u003eMinimum Operating Temperature\u003c\/td\u003e\n\u003ctd data-testid=\"specification-attributes-value\"\u003e-10°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-testid=\"specification-attributes-key\"\u003eMaximum Current\u003c\/td\u003e\n\u003ctd data-testid=\"specification-attributes-value\"\u003e100A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-testid=\"specification-attributes-key\"\u003eMaximum Operating Temperature\u003c\/td\u003e\n\u003ctd data-testid=\"specification-attributes-value\"\u003e+40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-testid=\"specification-attributes-key\"\u003eLength\u003c\/td\u003e\n\u003ctd data-testid=\"specification-attributes-value\"\u003e132mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-testid=\"specification-attributes-key\"\u003eWidth\u003c\/td\u003e\n\u003ctd data-testid=\"specification-attributes-value\"\u003e64mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"rockwell automations","offers":[{"title":"Default Title","offer_id":37673032646845,"sku":"440T-MRPSE100A","price":0.0,"currency_code":"NGN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0477\/6738\/8316\/products\/F3947536-01.jpg?v=1673365760","url":"https:\/\/www.powerpro.ng\/products\/allen-bradley-440t-mrpse100a-trapped-key-interlock","provider":"Powerpro Company Limited","version":"1.0","type":"link"}
