Part identity and intended use
It is rated at 80 A continuous current at AC-1, with a power circuit impedance of 1.5 mOhm per phase at 50 Hz, giving a per-phase dissipation of 4–5 W at 60 Hz coil excitation. Coil inrush at 60 Hz and 20°C is 140 VA. It is certified to UL 60947-4-1, CSA C22.2 No 14, IEC 60947-4-1, and EN 60947-4-1, covering the main North American and international standards for contactors used in motor and resistive load circuits.
Key ratings and their meaning
The AC-1 rating (80 A) governs its use on resistive loads. Electrical durability is 1.4 Mcycles at that current up to 440 V. Mechanical durability is 6 Mcycles. Operating time: opening 4–19 ms, closing 12–26 ms. Overvoltage category III suits fixed installation. Pollution degree 3 allows for conductive pollution environments. Shock resistance: 8 Gn open, 10 Gn closed; vibration: 2–3 Gn across 5–300 Hz. The coil is AC 60 Hz without built-in suppressor. Inrush power is 140 VA at 60 Hz; heat dissipation during holding is 4–5 W. Control circuit torque 15.05 lbf.in (1.7 N·m); power circuit up to 70.8 lbf.in (8 N·m) depending on conductor size.
The part carries a full set of third-party certifications (UL, CSA, IEC) so replacement with a non-certified alternate is not straightforward. No direct-form-fit-function cross is listed in the official documentation; any cross-sourcing must preserve the 4-pole, 80 A AC-1, 60 Hz coil footprint.
Mounting and terminal integration
Mounting support is rail and plate (sold separately). Front-face protection is IP20. Control terminals accept 1–4 mm². Strip length is per datasheet but the cage accepts 0.2–4 mm² on the control side. Dimensions: width 85 mm, height 127 mm, depth 125 mm.
