3-phase "zero crossing" power solid state unit for control of resistive and inductive loads, complete with aluminum heatsink and DIN guide connection. Integrated device designed for industrial applications demanding control of high power levels and frequent switching, with loads up to 3 x 55A (AC51) at 400/480/600Vac.
Control is logic type (Vdc), signaled by LEDs. Each phase is controlled by means of semiconductors .
The constructive elements, special production process, and new, sturdy case, provide excellent reliability and continuity of service. The device is sized for continuous operation at nominal current in a 40°C installation environment.
All versions are protected against overvoltages and against junction overtemperature, with signal LEDs and (optional) solid state alarm output.
The device is supplied complete with covers to protect against direct contacts (covers are removable for wiring).
Accessories available: fuses, fuse holders, support for panel mounting, thermostats and fans.
