- Dimensões de montagem central (Unidade: milímetros)
The following dimensions are categorized by frame size (Frame I/Frame II) e método de montagem (Fixed Type/Drawout Type), with weight references included for cabinet design and load-bearing calculation:
| Tamanho do quadro | Série de modelos | Método de montagem | Largura (C) | Altura (H) | Profundidade (D) | Peso (kg) |
| Frame I | 3WL1116 | Tipo Fixo | 320 | 434 | 291 | Aprox.. 45 |
| Frame I | 3WL1116 | Tipo de prolongamento | 320 | 434 | Aprox.. 450 | Aprox.. 55 |
| Frame II | 3WL1216 | Tipo Fixo | 460 | 434 | 291 | Aprox.. 56 |
| Frame II | 3WL1216 | Tipo de prolongamento | 460 | 434 | Aprox.. 450 | Aprox.. 65 |
- Principais instruções complementares
- Dimension Consistency and Differences
Unified Height: The standard height of all 3WL series disjuntores (Frame 0/I/II/III) é 434 mm, qual é o padrão de design unificado desta série, facilitating the interchangeable installation of different frame sizes.
Depth Variation:
A profundidade básica do tipo fixo é 291 mm (universal for Frame I/II), excluindo a parte saliente do mecanismo operacional.
The depth of the drawout type increases by approximately 160mm (espessura da base da gaveta), with a total depth of about 450mm.
Se equipado com um mecanismo operacional estendido ou outros acessórios especiais, a profundidade pode aumentar ainda mais.
Impacto do ETU45B-G-LCD: The type of electronic trip unit and display mode (LCD) não têm impacto significativo nas dimensões gerais, e afeta apenas o layout do painel frontal do disjuntor.
- Recommendations for Mounting Hole and Space Reservation
| Tamanho do quadro | 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 (for wiring) |
| Frame II | 450mm × 424mm | ≥50mm (for heat dissipation) | ≥100mm (for wiring) |
- Explanation of Mounting Methods
Tipo Fixo: Pequena ocupação de espaço e baixo custo, adequado para ocasiões onde a manutenção frequente não é necessária.
Tipo de prolongamento: Facilitates maintenance and replacement, ideal for key circuits. No entanto, 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
A série Siemens 3WL foi gradualmente atualizada para a série 3WA (por exemplo, 3WA1116-3EG45-4GA4), which retains exactly the same mounting dimensions (largura, altura, profundidade) 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.
- Para instalação fixa, 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.
