Wago | TOPJOB S 2-Conductor Ground Terminal Block 2.5mm2 | 100 Pack
The Wago 2202-1207 is a two-conductor ground terminal block with a 2.5mm2 nominal cross-section, supplied in a pack of 100. The 2202-1207 accommodates 0.25 to 4mm2 copper conductors, mounts to DIN-35 rail at 5.2mm wide, and terminates through push-button CAGE CLAMP with an integrated test port. The insulating housing is green-yellow polyamide PA66.
Control panels accumulate earth terminations faster than power circuits do, and each one consumes rail. At 5.2mm wide the block occupies less rail per position than heavier earth terminals, which matters across a bar carrying dozens of connections. The 0.25 to 4mm2 range covers instrumentation wiring through to standard domestic earth conductors.
An earth connection that cannot be demonstrated becomes a problem at inspection. The integrated test port accepts a probe, so continuity is verified while conductors remain terminated. Push-button CAGE CLAMP actuation maintains spring contact pressure independently of any screw, and two jumper slots permit commoning across adjacent blocks using a push-in jumper bar.
Features
- 2.5mm2 nominal cross-section — accepting 0.25 to 4mm2 solid or fine-stranded copper, or 22 to 12 AWG.
- Push-in termination limits — solid conductors push in from 0.75 to 4mm2, ferruled from 1 to 2.5mm2, with fine-stranded requiring the operating tool.
- Ferruled conductor range is narrower — an insulated ferrule reduces the fine-stranded range to 0.25 to 2.5mm2.
- Push-button CAGE CLAMP — orange actuator, front-entry wiring, 10 to 12mm strip length.
- Integrated test port — a probe point for continuity testing without disturbing the terminations.
- Two jumper slots — push-in jumper bars common adjacent blocks across a run.
- 5.2mm wide — 48.5mm high and 32.9mm deep from the upper edge of the DIN rail, at 8.1g per block.
- Green-yellow PA66 housing — polyamide to UL94 V0 flammability class, material group I, fire load 0.123 MJ.
- Minus 60 to plus 105 degrees C — continuous operating temperature across that full range.
- Hazardous area approvals — ATEX, IECEx, AEx, CCCEx and EAC, covering Ex eb IIC Gb and Ex eb I Mb.
- Marine approvals — ABS, Bureau Veritas, DNV GL and Lloyds Register, alongside UL 1059 listing.
- End plate required — Wago classifies an end and intermediate plate as a required accessory, ordered separately.
Where to use
- Control panel earth bars — the 2202-1207 builds a DIN rail earth bar with a test point at every position.
- Instrumentation earthing — small conductor terminations where the 0.25mm2 lower limit matters.
- Switchboard earth terminations — protective earth alongside protection devices on shared rail.
- Hazardous area assemblies — panels where ATEX or IECEx classification applies to the terminations.
- Marine and offshore panels — installations requiring ABS, BV, DNV GL or Lloyds Register approval.
- High-density earth runs — boards where 5.2mm per position materially reduces the rail length consumed.
The 2202-1207 is a green-yellow protective earth block and must not be used for active or neutral conductors. An end plate is a required accessory and is ordered separately, so allow for one at the end of each run. Wago publishes no rated current or nominal voltage for this block under IEC/EN 60947-7-2, so the earthing arrangement is sized by the installing electrician under AS/NZS 3000 rather than from a terminal rating.
