Part Status and Sourcing Reality
Specification Summary for Fit Verification
This is a 3-pole contactor (3NO main poles) from the Easy TeSys Control range, rated 9 A in AC-3 utilisation category at operational voltage up to 440 V. The coil is 380 V AC, 50/60 Hz. One normally-open auxiliary contact is included on the front. The AC-3 rating of 9 A is the figure that governs switching of standard squirrel-cage motors — this is the rating to match against the motor full-load current on the BOM line.
The contactor is fully compliant with EN/IEC 60947-1, EN/IEC 60947-4-1, EN/IEC 60947-5-1, and the corresponding GB/T standards. Permissible ambient air temperature around the device is -20 to 70 °C at Uc, with operation limited to -5 to 55 °C. Storage range is -60 to 80 °C.
Mechanical and Switching Characteristics
This ensures break-before-make operation for interlocking circuits — critical for reversing or star-delta starters where contact overlap would cause a phase-to-phase fault. Mechanical robustness is specified for vibration: 1.5 Gn (5–300 Hz) when open, 3 Gn (5–300 Hz) when closed. Shock resistance: 7 Gn for 11 ms when open, 10 Gn for 11 ms when closed. These figures confirm suitability for installation on machinery subject to moderate vibration.
