Commonly installed with DILM contactors in conveyor systems, pumps, compressors, HVAC equipment, and manufacturing machinery requiring overload and phase-failure protection. Maintenance teams, OEMs, and system integrators use this overload relay for equipment repairs, motor starter retrofits, and replacement of existing overload protection devices. \u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eApplications:\u003c\/h3\u003e\n\u003cp\u003eThe Klockner Moeller ZB12-6 is designed to provide thermal overload and phase-failure protection for three-phase motors in industrial environments. It is commonly used in motor control centers, conveyor systems, pumping stations, compressors, fans, and manufacturing equipment where reliable motor protection is required to minimize downtime and extend equipment life. The relay mounts directly to DILM7, DILM9, and DILM12 contactors to create compact motor starter assemblies. \u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp\u003e• Manufacturer Part Number (MPN): ZB12-6\u003cbr\u003e• Product Type: Thermal Overload Relay\u003cbr\u003e• Series: ZB12\u003cbr\u003e• Manufacturer: Klockner Moeller (Eaton)\u003cbr\u003e• Adjustable Current Range: 4 to 6 A\u003cbr\u003e• Relay Type: Electromechanical Thermal Overload Relay\u003cbr\u003e• Protection Functions: Overload Protection and Phase Failure Protection\u003cbr\u003e• Tripping Class: Class 10A\u003cbr\u003e• Number of Poles: 3\u003cbr\u003e• Auxiliary Contacts: 1 NO + 1 NC\u003cbr\u003e• Reset Function: Manual or Automatic Reset\u003cbr\u003e• Mounting Type: Direct Mount to Contactor\u003cbr\u003e• Compatible Contactors: DILM7, DILM9, DILM12\u003cbr\u003e• Rated Operational Voltage (Ue): Up to 690 VAC\u003cbr\u003e• Rated Insulation Voltage (Ui): 690 V\u003cbr\u003e• Rated Impulse Withstand Voltage (Uimp): 6 kV\u003cbr\u003e• Terminal Type: Screw Terminals\u003cbr\u003e• Degree of Protection: IP20\u003cbr\u003e• Operating Temperature Range: -25°C to +55°C\u003cbr\u003e• Dimensions (H × W × D): 120 × 45 × 88 mm\u003cbr\u003e• Standards: IEC\/EN 60947-4-1, UL 60947-4-1, CSA C22.2, VDE 0660\u003cbr\u003e• Certifications: CE, UL Listed, CSA Certified\u003cbr\u003e• Application Environment: Industrial motor control panels and automation systems \u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp\u003e• Eaton \u003ca href=\"https:\/\/plgautomation.com\/products\/xtob006bc1?_pos=1\u0026amp;_sid=b6477d088\u0026amp;_ss=r\"\u003eXTOB006BC1\u003c\/a\u003e\u003cbr\u003e• ABB TA25-DU60\u003cbr\u003e• Siemens\u003ca href=\"https:\/\/plgautomation.com\/products\/siemens-3ru1126-1fb0-overload-relay-3-5-5-a-size-s0-class-10-3ru11261fb0-ip20?_pos=1\u0026amp;_sid=a0d456bd9\u0026amp;_ss=r\"\u003e 3RU1126-1FB0\u003c\/a\u003e\u003c\/p\u003e","brand":"Undisclosed","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51728300146990,"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_4f17e197-966f-4572-b1cc-d91bdaecfffb.jpg?v=1770585906","url":"https:\/\/plgautomation.com\/products\/klockner-moeller-zb12-6-4-6a-thermal-overload-relay","provider":"PLG Automation ","version":"1.0","type":"link"}
