Description

Push-in feed-through terminal selection

PT terminals provide one level and one electrical potential. The standard versions have two connection points, TWIN versions have three and QUATTRO versions have four. Select the complete model for the required conductor size and number of connections; the connection points within one terminal share the same potential.

The IEC voltage and impulse ratings apply to overvoltage category III, pollution degree 3. Ratings for category III/pollution degree 2 and category II/pollution degree 2 are not specified. Maximum load current is a separate limit; use the nominal current and applicable conductor rating when selecting the terminal.

Conductor ranges and stripping lengths

Models	Solid conductor	Flexible conductor	Solid / flexible AWG	Flexible with ferrule	Strip length
PT1.5/S, PT1.5/S-TWIN, PT1.5/S-QUATTRO	0.14-1.5mm²	0.14-1.5mm²	26-16AWG	0.14-1.5mm²	8-10mm
PT2.5-TWIN, PT2.5-QUATTRO	0.14-4mm²	0.14-4mm²	26-12AWG	0.14-2.5mm²	8-10mm
PT4, PT4-TWIN, PT4-QUATTRO	0.2-6mm²	0.2-6mm²	24-10AWG	0.25-4mm²	10-12mm
PT6, PT6-TWIN, PT6-QUATTRO	0.5-10mm²	0.5-10mm²	20-8AWG	0.5-6mm²	10-12mm

For PT10, PT10-TWIN and PT16N, 18mm is the nominal stripping value within the 18-20mm range. Push-in connections do not use a locking screw or a screw tightening torque.
