APC TeSys D kontakti 3P 25A AC-3 24V AC 1NO+1NC LC1D25B7

The APC LC1D25B7 is a high-performance TeSys D contactor designed for reliable motor control and switching applications. With 3 poles, a rated operational current of 25 A in AC-3 category (up to 440 V) and 40 A in AC-1 (up to 690 V), it handles motor loads up to 11 kW at 380-400 V. The 24 V AC 50/60 Hz coil ensures safe and efficient operation. Built with screw clamp terminals and IP20 protection, it mounts on DIN rail or with screws. This contactor includes 1 normally open and 1 normally closed auxiliary contact for added flexibility.

Advantages

Compact design saves panel space. High electrical and mechanical durability reduces maintenance. Wide operating temperature range (-5 to 60 °C) suits demanding environments. Integrated auxiliary contacts eliminate need for separate modules.
