The Phoenix Contact 1731857 (MKKDSNH 1,5/ 4-5,08) is a 4-position, single-level wire-to-board PCB terminal block with a 5.08mm pitch. It uses a screw connection with a rising cage clamp termination style, designed for horizontal mating orientation to the PCB.
Electrically, the terminal block is rated for 13.5A nominal current (IEC) and 400V rated voltage (IEC, III/2), with additional ratings of 250V (III/3) and 630V (II/2). UL ratings are 10A/300V for Use Groups B and D. The rated surge voltage is 4kV. It accepts wire sizes from 26 to 16 AWG (0.14 to 1.5 mm² solid/stranded) and requires a stripping length of 6mm.
Mechanically, the block is through-hole mounted and has an M3 screw with a tightening torque of 0.5 Nm (max 0.6 Nm). Pin dimensions are 0.5 x 1 mm with a 1.3 mm hole diameter. The housing length is 8.6 mm and dimension a (center to end) is 15.24 mm.
The insulating material is polyamide (PA) with a flammability rating of UL 94 V0. The part features high wire entry level and side interlocking for multi-position assembly. Note: compliance data (RoHS, REACH, MSL) is unverified.
The 1731857 has 4 positions.
The pitch is 5.08 mm.
The IEC nominal current is 13.5 A; the UL current rating is 10 A (Group B/D).
It has multiple ratings: IEC rated voltage is 400 V (III/2), 250 V (III/3), and 630 V (II/2). UL rated voltage is 300 V (Group B/D).
It is a through-hole mount terminal block.
The datasheet specifies 26-16 AWG; existing database shows 14-30 AWG. Please verify the correct range for your application.
It uses an M3 screw with a tightening torque of 0.5 Nm (min) to 0.6 Nm (max).
