80 A AC-1 resistive load contactor for panel builders
The LP1D65008FW: That 80 A figure governs the continuous current through the power poles when switching heaters, ovens, or lighting banks — not motor starting, which would fall under AC-3 and be lower. The 4-pole configuration with 2 NO + 2 NC contacts gives you the flexibility to switch two independent load circuits or use the NC pair for interlocking or status feedback. The DC wide-range control coil includes a built-in bidirectional peak limiting diode suppressor, so you don't need an external flyback diode across the coil — one less component on the panel layout. Power dissipation per pole runs 9.6 W at AC-1 rating, which adds up to 38.4 W total through the contactor body; account for that thermal load when spacing devices in the enclosure.
Making and breaking capacity for fault coordination
The associated fuse recommendation is 125 A gG at up to 690 V for type 2 coordination, which keeps the contactor serviceable after a short circuit rather than requiring replacement. Electrical durability is 1.4 million cycles at 80 A AC-1, 440 V. Mechanical durability stretches to 6 million cycles — the gap between those numbers tells you the contact wear under load is the life limiter. For applications that cycle infrequently (like oven contactors), the mechanical life is essentially infinite.
Safety reliability and standards compliance
Safety reliability is quantified with B10d values: 1,369,863 cycles under nominal load and 20,000,000 cycles under mechanical load per EN/ISO 13849-1. That B10d at nominal load is the figure to plug into your safety circuit PFHd calculation — the higher mechanical B10d applies only when switching no current. The contactor carries approvals to CSA C22.2 No 14, EN 60947-4-1, EN 60947-5-1, IEC 60947-4-1, IEC 60947-5-1, and UL 508. Flame retardance is V1 per UL 94; fire resistance tested to 850 °C per IEC 60695-2-1.
Panel fit and termination
Dimensions are 7.2 in deep by 3.3 in wide by 5 in tall (182 x 85 x 127 mm). The 4-pole width is the same as a 3-pole TeSys Deca contactor — the extra pole fits within the same footprint. Mounting is rail or plate, which covers both DIN rail and direct panel screw-down. Tightening torque is 70.8 lbf·in (8 N·m) for power connections — use a torque screwdriver to avoid terminal damage. Control circuit terminals are smaller: 1.7 N·m for up to 4 mm² wire. Front face is IP20 per IEC 60529, which is standard for enclosed panel mount — finger-safe from the front but not sealed against dust ingress. The operating altitude range is 0 to 3000 m without derating.
