The current clamp Current clamp Pawbol E.4145 1X2.5-35mm² grey 800V 135A aluminium and plastic DIN rail mount is compared with three alternative universal terminal blocks from the NORDEL NLT135 series: the blue NORDEL NLT135 Universal Terminal Block 1x2.5-35 mm² for Aluminum and Copper Conductors, Blue, the grey NORDEL NLT135 Universal Terminal Block 1x2.5-35 mm² for Aluminum and Copper Conductors, Grey, and the yellow/green NORDEL NLT135 Universal Terminal Block 1x2.5-35 mm² for Aluminum and Copper Conductors, Yellow/Green. All reviewed products support the same conductor cross-section range of 2.5 to 35 mm² for secure electrical connections. The main practical differences lie in the body materials, color-coding, electrical ratings, and specific conductor compatibility.
⚙️ The table below compares characteristics such as conductor cross-section range, construction materials, color coding, maximum voltage and current ratings, and mounting features.
| Parameter | Pawbol E.4145 | NORDEL NLT135 Blue | NORDEL NLT135 Grey | NORDEL NLT135 Yellow/Green | Practical significance |
|---|
| Conductor cross-section | 2.5–35 mm² | 2.5–35 mm² | 2.5–35 mm² | 2.5–35 mm² | All products accommodate the exact same wire size range for secure clamping. |
| Conductor compatibility | Aluminum | Aluminum and copper | Aluminum and copper | Aluminum and copper | NORDEL models support both copper and aluminum, whereas Pawbol is tailored for aluminum conductors. |
| Housing color | Grey | Blue | Grey | Yellow/Green | Color coding assists in visually organizing phase, neutral, and protective earth wires in distribution boards. |
| Electrical ratings | Up to 800 V and 135 A | Not specified | Not specified | Not specified | The Pawbol model features explicitly stated manufacturer voltage and current performance limits. |
| Materials and mounting | Aluminum and plastic, DIN rail | Not specified | Not specified | Not specified | The Pawbol model highlights robust build materials and standard DIN rail installation capability. |
◎ The table below evaluates the suitability of each product for various use cases and application scenarios.
| Use case | Recommended product | Why |
|---|
| Industrial and commercial distribution setups requiring explicit electrical limits | Pawbol E.4145 | Provides clearly defined ratings of up to 800V and 135A for aluminum wiring systems. |
| Standard phase or neutral wiring with copper or aluminum conductors | NORDEL NLT135 Blue | The blue color is practical for identifying neutral or specific phase lines in universal setups. |
| General electrical installations in residential and commercial buildings | NORDEL NLT135 Grey | The grey universal block fits standard wiring layouts using either copper or aluminum cores. |
| Protective earthing and grounding applications | NORDEL NLT135 Yellow/Green | The yellow/green color coding is specifically designed for secure and compliant grounding connections. |
The Pawbol E.4145 clamp is distinguished by specified ratings of 800V and 135A, tailored for aluminum conductors in industrial and commercial environments. NORDEL products offer the advantage of universal copper and aluminum compatibility combined with color options for clear circuit organization. Choose Pawbol when explicit electrical thresholds are required, or select NORDEL models for flexible copper-aluminum usage and dedicated earthing or neutral color identification.
