subkasten

Subkasten is a term used in German-speaking technical contexts to denote a secondary enclosure or sub-box that is part of a larger system. The word combines Sub- (below or subordinate) with Kasten (box or enclosure). In English-language contexts it may be described as a sub-box, sub-enclosure, or subassembly housing, depending on the field.

In electronics and automation, a Subkasten often refers to a modular enclosure within a control cabinet or housing that contains specific subsystems such as a power supply, drive electronics, or I/O modules. Its purpose is to segregate functions for electrical safety, electromagnetic compatibility, maintenance, and cooling, while allowing standardized mounting interfaces and cable management.

In consumer devices, a Subkasten can be an internal modular cavity designed to isolate thermal zones or functional blocks, enabling easier manufacturing and service without altering the main enclosure.

Design considerations include mechanical compatibility with the host equipment, material selection (metal or high-strength plastics), protection class (IP ratings), thermal management, grounding and shielding, and accessibility for service. Dimensions, mounting patterns, and gasketing are specified to maintain enclosure integrity in the intended environment.

Materials range from sheet metal to injection-m molded plastics. While not a universal term, Subkasten is commonly used in German documentation and is often translated as sub-enclosure or sub-box in international contexts.
