700 A resistive-load contactor — what the ratings mean for fit
The LC1F5002 is a 2-pole TeSys F contactor rated 700 A in AC-1 utilisation category at ≤440 V, 40 °C. AC-1 covers resistive loads — heaters, ovens, lighting banks — where the switching current equals the steady-state current. This is not a motor-starting contactor; the AC-3 rating would be lower. The contactor carries 2 NO power poles. The control circuit accepts 48-1000 V AC 40-400 Hz with LX1/LX9 coil options, or 48-440 V DC with LX4 coil. Inrush power is 1050-1150 VA AC; hold-in drops to 16-20 VA.
Lifecycle status — EOL hot, plan the replacement
Mechanical durability is rated 10 Mcycles. Maximum operating rate is 2400 cycles/hour at 55 °C. Heat dissipation is 18 W total, 88 W per pole in AC-1 duty.
