- Core Mounting Dimensions (Unitate: mm)
The following dimensions are categorized by frame size (Frame I/Frame II) and mounting method (Fixed Type/Drawout Type), with weight references included for cabinet design and load-bearing calculation:
| Dimensiunea cadrului | Seria de modele | Metoda de montare | Lăţime (W) | Înălţime (H) | Adâncime (D) | Greutate (kg) |
| Frame I | 3WL1116 | Tip fix | 320 | 434 | 291 | Aproximativ. 45 |
| Frame I | 3WL1116 | Tip de tragere | 320 | 434 | Aproximativ. 450 | Aproximativ. 55 |
| Frame II | 3WL1216 | Tip fix | 460 | 434 | 291 | Aproximativ. 56 |
| Frame II | 3WL1216 | Tip de tragere | 460 | 434 | Aproximativ. 450 | Aproximativ. 65 |

- Dimension Consistency and Differences
Unified Height: The standard height of all 3WL series întreruptoare de circuit (Frame 0/I/II/III) este de 434 mm, care este standardul de proiectare unificat al acestei serii, facilitating the interchangeable installation of different frame sizes.
Depth Variation:
Adâncimea de bază a tipului fix este de 291 mm (universal for Frame I/II), excluzând partea proeminentă a mecanismului de acționare.
The depth of the drawout type increases by approximately 160mm (grosimea bazei sertarului), with a total depth of about 450mm.
Dacă este echipat cu un mecanism de operare extins sau alte accesorii speciale, adâncimea poate crește și mai mult.
Impactul ETU45B-G-LCD: The type of electronic trip unit and display mode (LCD) nu au un impact semnificativ asupra dimensiunilor generale, și afectează numai aspectul panoului frontal al întreruptorului.
- Recommendations for Mounting Hole and Space Reservation
| Dimensiunea cadrului | Recommended Mounting Hole Dimension (W×H) | Spacing Between Adjacent Circuit Breakers | Space Reservation for Top/Bottom |
| Frame I | 310mm × 424mm | ≥50mm (for heat dissipation) | ≥100mm (pentru cablare) |
| Frame II | 450mm × 424mm | ≥50mm (for heat dissipation) | ≥100mm (pentru cablare) |
- Explanation of Mounting Methods
Tip fix: Ocuparea spațiului mic și cost redus, potrivit pentru ocazii în care nu este necesară întreținerea frecventă.
Tip de tragere: Facilitates maintenance and replacement, ideal for key circuits. Cu toate acestea, it occupies more space, and attention should be paid to the installation space of the drawer base and the operating distance (≥600mm is recommended).
- Dimension Compatibility for Replacement and Upgrade
Seria Siemens 3WL a fost actualizată treptat la seria 3WA (de ex., 3WA1116-3EG45-4GA4), which retains exactly the same mounting dimensions (lăţime, înălţime, adâncime) and can be directly replaced without cabinet modification.
III. Engineering Application Notes
- When designing the cabinet, consideration should be given to the operating space of the drawout circuit breaker to ensure that the drawer can be fully pulled out for maintenance.
- For fixed installation, cable connection space must be reserved, especially the bending radius requirements for vertical incoming/outgoing cables.
- For drawout circuit breakers weighing more than 50kg, it is recommended to design load-bearing reinforced structures for the cabinet.
- The installation environment must meet the requirements of protection class. The fixed type body has a protection class of IP30, which can be upgraded to IP40 with a protective cover installed.
