Rittal Junction Boxes
rittal installation boxes for clean, compliant field wiring
Installers choose Rittal when junction points must stay watertight, impact‑resistant, and easy to service. The lineup spans compact terminal housings for single drops up to wall‑mount enclosures that carry protection, metering, and small control assemblies. Fast mounting, reliable sealing, and standardized accessories keep multi‑site rollouts predictable.
Product range and formats – rittal enclosure boxes
Compact junction housings. Small footprints for terminal blocks, glands, and splices; square or rectangular footprints with pre‑marked entries. Materials include UV‑stabilized polycarbonate (PC) for outdoor use and ABS for indoor plant rooms; metal variants in sheet steel or stainless AISI 304/316 handle harsher sites.
Wall‑mount enclosures. Taller bodies accept DIN rails, mini mounting plates, and shallow devices (PSUs, relays, I/O). Options include solid doors or clear windows for visual checks without opening.
Hinged service boxes. Quick‑access door hardware, quarter‑turn locks, and perimeter gaskets accelerate maintenance while keeping the gasket line intact. Depth options accommodate cable bend radii and DIN accessories.
Sizes typically run from hand‑sized housings to 600×400×200 mm class bodies. Protection levels reach IP54–IP66 (EN 60529) with impact ratings up to IK08–IK10 (EN 62262) when combined with the correct gland plates and mounting.
Technical specifications and standards
- Ingress & impact: sealing via foamed‑in‑place or replaceable gaskets; IP rating depends on entry treatment (solid/split/brush plates, metric glands M16–M50). Impact per IK08/IK10 where specified.
- Materials & finish: PC/ABS with UV stabilization; sheet steel powder‑coat (typ. RAL 7035) for indoor; AISI 304/316 for food/coastal zones. Clear lids use UV‑stable PC to resist yellowing.
- Mounting: rear bosses for rails/plates, internal studs for earth points, external wall brackets and plinth adaptors for rapid alignment. DIN rail EN 60715 TS35/TS15 supported.
- Thermal & condensation: optional pressure equalization elements and drain plugs; gland orientation and drip edges minimize water pooling.
- Compliance context: empty enclosures per IEC/EN 62208; assembled systems typically verified to IEC 61439 parts depending on content. EMC versions use conductive gaskets and bonding kits. Fire behavior for plastics aligns with UL 94 V‑0 families on selected references.
- Environment: operating ambient commonly −25…+60/70 °C; stainless hardware recommended for chlorinated or coastal air.
Design note: choose transparent lids for status viewing or metering; solid doors improve EMC and reduce UV ingress in sun‑exposed installs.
Applications and compatibility – rittal junction boxes
- Lighting and signage: splice hubs for façade luminaires, pole bases, canopy lines; restore IP with matched glands and cable bushings. Keep PE bonding continuous across gear plates.
- Building services: terminal hubs for pumps, fans, blinds; small DIN assemblies with relays, timers, and power supplies. Clear windows help maintenance without breaking IP.
- Industrial/OEM: sensor/actuator nodes, distributed I/O, and safety signal routing; stainless enclosures for wash‑down zones.
Cable management pairs with internal DIN rails and duct stubs. Where multiple cables enter, use split plates or membrane systems to keep the seal intact and avoid ad‑hoc drilling.
Integration with other Rittal products – rittal mounting boxes
These housings accept the same TS35 rails, earth kits, clamp rails, and marker systems used in larger cabinets, so installers keep one accessory ecosystem. For outdoor poles or façades, combine with pressure equalizers and stainless fixings; in IT‑adjacent areas, add EMC gland plates and bonding to protect control/data lines. Depth rails and mini plates allow small PSUs and interface relays to mount securely without flex.
If your layout includes upstream cabinets, align marker pitch and terminal families so documentation and spares remain consistent across the estate.
Selection criteria for B2B clients – rittal electrical enclosures
- Protection targets — pick IP/IK classes based on site (indoor plant rooms vs outdoor poles). For coastal/wash‑down zones, use stainless bodies and A4 fasteners.
- Space & layout — confirm DIN rail height, device depth, and bending radii for the thickest cable; plan spare space for future drops.
- Cable entry strategy — metric size mix (M16–M50), split vs solid plates, and bushings; define the strain‑relief scheme to EN 62444.
- Bonding & EMC — include PE studs and bonding straps; use conductive gaskets and EMC plates where screened cables terminate.
- Serviceability — hinged or windowed doors for frequent inspection; quarter‑turn locks and captive screws reduce lost hardware on site.
Procurement often standardizes one polycarbonate line for outdoors, one steel line for interiors, and a stainless option for aggressive environments.
Distribution and metering use – rittal distribution enclosures
Small distribution builds (metering, breakers, contact protection) benefit from deeper housings, removable mounting plates, and clear door options for visual checks. Coordinate RCD/MCB spacing and heat‑dissipation paths; leave clearance above and below rails for conductor sweep and finger‑safe access.
