Product information

Description

Rittal SZ 4140.840 is a compact industrial LED cabinet light in white designed to provide efficient interior illumination for electrical enclosures, control cabinets and machine housings. Supplied as a single unit, this system light fits into tight spaces and is intended for retrofit or new installations where uniform, task-oriented lighting is required. The design emphasises low-profile mounting and energy-efficient LED performance to improve visibility of components, wiring and control elements inside panels.

Advantages

The compact LED module delivers consistent, glare-minimised illumination while consuming little power and producing minimal heat. Its white housing integrates with standard cabinet interiors and allows simple replacement or addition of lighting without major modifications. The unit is designed for reliable continuous operation in industrial environments and offers improved visibility for inspection, wiring and maintenance tasks.

Suitable for

  • Illuminating electrical control cabinets and distribution panels
  • Lighting machine housings and equipment enclosures
  • Retrofit upgrades where space is limited
  • Work areas inside racks, switchgear and instrumentation cabinets

When it may not be suitable

This compact cabinet light is intended for interior task illumination and may not be suitable as the primary room lighting source in large service areas. It is designed for use inside enclosures; outdoor or unprotected installation without appropriate housing or conformal protection is not recommended.

Key specifications

  • Light source: LED
  • Colour: white housing, neutral illumination suitable for technical interiors
  • Form factor: compact system light for cabinet mounting
  • Supply: supplied as a single unit for direct installation
  • Application: interior lighting for enclosures, control cabinets and machine housings

How to use

Install the Rittal SZ 4140.840 inside the enclosure at a position that provides even illumination of the working area. Mounting is performed according to the cabinet manufacturer’s instructions and local electrical regulations. Connect the unit to the appropriate control cabinet power supply using the correct wiring and protective devices. Place the light to avoid direct glare into the operator’s eyes and to illuminate wiring ducts, terminal strips and control elements.

What to consider before purchase

  • Verify cabinet internal dimensions and available mounting points to ensure the compact light fits the intended location
  • Confirm compatible supply voltage and connection method with your cabinet power system
  • Assess whether the unit’s interior-only design meets your environmental and protection requirements
  • Check whether multiple units are needed for uniform illumination of larger enclosures

Usage recommendations

For consistent task lighting, place the LED module to minimise shadows on terminals and controls; combine multiple units for larger cabinets and follow Rittal mounting guidelines and applicable electrical safety standards during installation.
