Are the fixing screws included?

No. The flange version is screwed onto the enclosure wall and the screws must be ordered separately. With the nut version of the series, the mounting nut is included.

How does the flange version differ from the nut version?

Only in the fixing method. Both have an M25 thread and both allow up to 7 mm panel thickness. The flange version has a plate with screw holes on the outside of the wall; the nut version is secured from inside. Electrically they are identical.

What does the 5-pole L-N-E version mean?

It carries contact marking 1-2-L-N-E instead of 1-2-3-4-5: two signal contacts plus a mains connection with line, neutral and protective earth in one connector. In the flange range it is available only as a panel plug connector.

Why is the conductor cross-section smaller on 5-pole versions?

Because the insert is more densely populated. The 3-pole inserts accept 0.5 to 2.5 mm² and clamp with M3 screws at 0.8 Nm; the 5-pole inserts accept 0.25 to 1.5 mm² with M2 screws at 0.2 Nm.

Does the current rating apply in North America too?

No. Under IEC the series is rated 17.5 A at 500 V, while the UL/CSA listing to UL 2238 is 7 A at 600 V. If your assembly goes to the UL market, the lower rating applies.

Description

The flange versions of the TH387 series are screwed onto the enclosure wall with a flange plate and accept the matching cable connector. They are rated for 17.5 A at 500 V AC.

Mounting

The thread is M25, maximum panel thickness is 7 mm. Unlike the nut version, a flange plate with screw holes sits on the enclosure wall. The fixing screws are not included and must be ordered separately.

Versions and pole counts

Available as panel plug connector and panel socket connector, each with 2, 3, 4 and 5 poles as well as the earthed versions 2+PE, 3+PE and 4+PE. The 5-pole plug is also available with contact marking 1-2-L-N-E — two signal contacts plus mains in a single connector.

Conductor cross-section depends on the pole count: 0.5 to 2.5 mm² on the 3-pole inserts (M3, 0.8 Nm), 0.25 to 1.5 mm² on the 5-pole inserts (M2, 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 seals TPE, the contacts brass. The temperature range runs from −40 to +125 °C with a maximum operating temperature of +60 °C. Halogen-free and silicone-free, tested to EN 61984, with CE and UKCA marking and a UL/CSA listing to UL 2238 (7 A at 600 V there).
