It also carries AC-1 and AC-4 utilisation categories, so it handles resistive loads and plugging/inching duty as well. The 110 V AC coil is built in; the contactor has 3 NO power poles and one NC auxiliary contact. Ambient temperature range for operation is -25 to 50 °C, with storage from -50 to 80 °C.
If you are qualifying a replacement, look for a TeSys K or TeSys D reversing contactor with the same pole configuration, AC-3 current rating (12 A at 440 V), and 110 V AC coil voltage.
The critical specs are: reversing contactor, 3 NO power poles, AC-3 rated 12 A at ≤440 V, 110 V AC coil, and the physical footprint of 90 mm wide × 58 mm high × 57 mm deep. The utilisation categories are AC-1, AC-3, and AC-4. Any replacement must also have IP20 minimum protection for enclosed panel use.
The part carries flame retardance V1 per UL 94 and also meets NF F 16-101 and NF F 16-102 (railway fire-smoke-toxicity). Protective treatment conforms to IEC 60068 and DIN 50016. Mechanical robustness is qualified per IEC 60068-2-27 (shock) and IEC 60068-2-6 (vibration).
