PLC distribution box dimensions

PLC distribution boxes come in various sizes and configurations, typically ranging from small 1-way enclosures to large 36-way units, with IP protection, modular mounting, and flexible cable entry options.

Dimensions and Configurations

PLC distribution boxes are available in multiple sizes depending on the number of modules or ways they support. Common ranges include:

• Small enclosures: 65 x 65 mm up to 361 x 254 mm, with multiple cover heights available .
• Modular boxes: 1-way to 36-way configurations, with dimensions specified for length, width, and height for each type (e.g., TOP-TS, TOP-TF, TOP-LS, TOP-PS, TOP-PF, TOP-S), .
• Consumer units: Available in 7, 10, 15, and 20 modules, allowing flexible design for domestic or commercial applications .

Material and Construction

• Typically made from steel or heavy-duty plastic, with smooth or textured surfaces .
• Doors and covers often include transparent flaps for visual inspection and removable screws for secure mounting .
• Hinges are designed for durability, often stainless steel pins with internal mounting to prevent tampering .

Protection and Safety

• IP ratings: Commonly IP33 or higher, providing protection against dust and water ingress .
• Busbars and terminals: Shrouded for safety, with aluminum busbars sized according to load (e.g., 72x50x8 mm for 63/100 KVA, 1120x50x15 mm for 160/315 KVA boxes), .
• Cable entry: Knock-outs on top, bottom, and rear for flexible wiring; gland plates can be removed or extended .

Mounting and Installation

• Boxes include studs and adjustable nuts for easy mounting and removal of pan assemblies .
• Modular DIN rail components allow installation of MCBs, RCCBs, or other protection devices without obstructing adjacent modules .
• Adequate wiring space is provided to facilitate neat and safe connections .

Additional Features

• Heat dissipation: Louvers or perforated sheets are included to prevent overheating .
• Customization: Many boxes allow factory-fitted or field-installed incoming devices, offering flexibility for PLC and automation setups .
• Cable lengths: Standard cable lengths range from 1 m to 10 m, depending on application . These specifications ensure that PLC distribution boxes are suitable for industrial, commercial, and domestic applications, providing modularity, safety, and ease of installation while accommodating a wide range of PLC and electrical components.
