TH387 Kabelsteckverbinder 3 polig

The TH387 is Techno's mini circular connector — 23 mm outside diameter, rated for 17.5 A at 500 V AC. It sits between the smaller TH381 and the panel-mount series and is the choice when more than three cores have to pass through a watertight separation point.

Cable-mounted versions

This page shows the versions for cable mounting: cable plug connector and cable socket connector, each with 2, 3, 4 and 5 poles as well as the earthed versions 2+PE, 3+PE and 4+PE. Locking is by screw coupling; the series is rated for 1000 mating cycles.

Cable diameters

The standard gland accepts cables from 7 to 12 mm, the extended version from 7 to 13.5 mm — there the sheath is stripped to 25 mm instead of 20 mm. Both are available from the variant selection. The conductor is stripped to 6 mm.

The permissible conductor cross-section depends on the pole count: 0.5 to 2.5 mm² on the 3-pole inserts, with an M3 terminal screw at 0.8 Nm; 0.25 to 1.5 mm² on the 5-pole inserts, with an M2 terminal screw at 0.2 Nm.

Protection and materials

Protection rating is IP66 and IP68 (30 m / 3 h), impact resistance IK07. The housing is glass-fibre reinforced PA66 to UL94 V0, the gland PA66 to UL94 V2, the seals TPE, the contacts brass. The temperature range runs from −40 to +125 °C with a maximum operating temperature of +60 °C. The series is halogen-free and silicone-free.

Tested to EN 61984, with CE and UKCA marking and a UL/CSA listing to UL 2238. Note that the North American rating differs: 7 A at 600 V.
