NO - SP - ST

The IT400 is a single pole high current contactor developed for the 1U market and is rated at 400A Continuous.  An extension to our 1U range, it shares the requirements of conforming to a 1U fitment as well as a height that allows it to fit within a 2U constraint.

The IT400 has been designed by Albright for compact Communication Power Systems.  Our 5G solutions have been developed by Albright specifically for the demands of high power and reduced footprint with a 1U profile.  The IT400 is fitted with flying leads and plug and is available in voltages up to 96V DC with auxiliary options and a variety of coil voltages offered.
