Phoenix Contact Material Change to Housing for PCV/PC Terminal Blocks Phoenix Contact is changing the insulation material for the 10- to 12-pole PC(V) 4 housings from PA to PBT. The reason is for the optimization of production. The CTI value will change from PA with 600 to 225 for PBT. Certifications and any further technical data are not affected by this change. During transition of the changes listed above, Mouser may supply both products simultaneously depending on inventory.
