The Schneider Electric 13976 is a Mini Kaedra Mureva surface-mount enclosure for modular DIN-rail equipment, holding up to 4 × 18 mm modules in a single horizontal row. Constructed from self-extinguishing polymer with a transparent green door and light grey (RAL 7035) body, it provides IP65 ingress protection and IK09 impact resistance, suitable for outdoor and wet-area installations. Class II double insulation eliminates the need for protective earthing.Technical specifications: Catalog reference: 13976 Manufacturer: Schneider Electric Range: Mureva (Mureva Enclosure / Mini Kaedra) Product type: Waterproof enclosure for modular equipment Mounting: Surface-mount Module capacity: 4 × 18 mm modules, 1 horizontal row 9 mm pitch: 8 Nominal current [In]: 63 A Power dissipation: 10 W Insulation class: Class II (double insulation) Rail type: DIN PG/ISO knockouts: 3 Front face: Transparent (green) Body colour: Light grey (RAL 7035) Enclosure material: Self-extinguishing polymer IP rating: IP65 per IEC 60529 IK rating: IK09 per EN 50102 Fire resistance: 650 °C per IEC 60695-2-1 UV resistance: Class 3 per ISO 4582:2010 Overvoltage category: II Operating temperature: -25 to +60 °C Width × Height × Depth: 123 × 200 × 112 mm Inner depth: 56 mm Standards: IEC 60670-1, IEC 60670-24, EN 50262, IEC 60695-2-1 Recyclability potential: 86% Warranty: 18 months Features and benefits: IP65 / IK09 dual sealed construction protects modular devices in outdoor, damp, or industrial environments. Class II double insulation removes the need for a protective earth connection to the enclosure. Self-extinguishing polymer withstands 650 °C glow-wire fire testing for safe distribution-board installation. Transparent door allows visual circuit inspection without breaking the IP seal. Optional safety lock available for restricted-access installations. Applications: Outdoor distribution enclosures exposed to rain, dust, or temporary water jets. Agricultural buildings, garages, garden sheds, and marine areas requiring sealed modular protection. Industrial wash-down zones and humid environments where standard indoor boards are unsuitable. UV-exposed sites where standard polycarbonate enclosures would degrade. Note: this catalog reference is marked discontinued by Schneider Electric. Functional replacement may be available from the same Mureva product range.
