Parameter Specification Manufacturer & Model Eaton XTCE012BC01 Product Series XTC Series Auxiliary Contact Block Contact Configuration 1 Normally Open (NO) + 1 Normally Closed (NC) Rated Operational Current (Ie) AC-15: 3 A @ 230/400 V AC DC-13: 0.2 A @ 24 V DC Utilization Category (Control Circuit) AC-15: For switching AC electromagnetic loads (e.g., relay, contactor coils). DC-13: For switching DC electromagnetic loads. Rated Insulation Voltage (Ui) 690 V Conventional Free-Air Thermal Current (Ith) 10 A Maximum Permissible Wire Size 2.5 mm² (14 AWG), screw clamp terminals. Electrical Endurance > 10 million operations (at rated load). Mechanical Endurance > 20 million operations. Degree of Protection IP20 (when mounted on contactor and installed inside an enclosure). Ambient Temperature Range -25°C to +60°C Mounting Method Side-mounted onto compatible Eaton contactors (e.g., DILM7 to DILM150). Standards & Approvals IEC/EN 60947-5-1, CE, CCC, etc. Material (Contact) Silver Alloy Primary Function Provides additional NO and NC contacts that are mechanically operated by the main contactor's movement, allowing for control circuit expansion (e.g., signaling to a PLC, interlocking, pilot light control).
