KRM end fixing screws are M2.5 with a tightening torque of 0.4N·m, separate from its M3 wire-clamp screws. Fixing thread sizes for KRP and KRPF are unspecified. Mating compatibility requires checking contact geometry, keying and fixing dimensions.
All five conducting plug models are rated 20A, 320V under overvoltage category III and pollution degree 2. Select the model-specific rated impulse voltage below.
| Model | Overvoltage category | Pollution degree | Rated voltage | Rated impulse voltage |
|---|---|---|---|---|
| 2KR | III | 2 | 320V | 2.5kV |
| 2KRP | 4kV | |||
| 2KRM | 2.5kV | |||
| 2KRF and 2KRPF | 4kV |
Ratings for category III/pollution degree 3 and category II/pollution degree 2 are unspecified. KRZM has no IEC voltage, current or impulse rating.
| Model | Use group B | Use group C | Use group D | UL wire range |
|---|---|---|---|---|
| 2KR, 2KRP and 2KRM | 15A, 300V | Not specified | 10A, 300V | 28–12AWG |
| 2KRF and 2KRPF | 28–16AWG | |||
| 2KRZM | Not applicable to the insulating frame | |||
2KRF and 2KRPF also have a general UL-standard notation of 16A, 300V without a use group; this does not extend the B or D limits above. Their dielectric withstand test is 1600VAC for 1 minute. Equivalent wire-clamp torque notations are 4.43lb·in for M3 plugs and 3.54lb·in for the M2.5 F/PF plugs.
| Model | IEC conductor cross section | Conductor types |
|---|---|---|
| 2KR | 0.2–2.5mm² | Solid, flexible or flexible with ferrule |
| 2KRP | 1.0–2.5mm² | |
| 2KRM | ||
| 2KRF and 2KRPF | 0.2–2.5mm² |
IEC conductor ranges and UL wire ranges apply under their respective rating systems. Select the wire size for the circuit current and termination requirements.
