WIEGMANN

WIEGMANN is a brand of industrial enclosures and related accessories, manufactured by a company with a history dating back to the early 20th century. The brand is known for producing a wide range of enclosures designed to protect electrical and electronic equipment in various industrial environments. WIEGMANN's product families include steel enclosures, stainless steel enclosures, fiberglass enclosures, push button enclosures, console enclosures, and interior mounting panels. These products are used in applications such as manufacturing, process control, water treatment, and oil and gas, where equipment must be safeguarded against dust, moisture, corrosion, and physical impact. WIEGMANN enclosures are available in multiple NEMA ratings, including NEMA 1, 12, 13, 3R, 4, 4X, and 6P, covering indoor and outdoor use, washdown environments, and submersible conditions. The enclosures are constructed from materials such as carbon steel, stainless steel, and fiberglass, with finishes like powder coating or painting to enhance durability. Sizes range from small push button enclosures (e.g., 8 in x 12 in x 7 in) to large wall-mount enclosures (e.g., 36 in x 42 in x 12 in) and interior panels up to 60 in x 44 in. WIEGMANN also offers accessories such as back panels, hinges, and closure mechanisms (screws, quarter-turn latches, padlock hasps). 3G Electric supplies over 900 SKUs of WIEGMANN products globally, including the 6XC and 487 series, providing engineers and procurement specialists with a comprehensive selection for specifying enclosures that meet specific environmental and dimensional requirements. The brand's focus on standardized NEMA ratings and robust construction makes it a practical choice for industrial applications where reliability and compliance with protection standards are critical.

  • Manufacturing plant – WIEGMANN steel enclosures (e.g., NEMA 12) for housing motor controls and PLCs in dusty environments.
  • Water treatment facility – WIEGMANN fiberglass submersible enclosures (e.g., NEMA 6P) for outdoor pump control panels.
  • Oil and gas industry – WIEGMANN stainless steel enclosures (e.g., NEMA 4X) for corrosion-resistant protection in offshore platforms.
  • Food processing – WIEGMANN washdown enclosures (e.g., NEMA 4) for housing electrical components in high-pressure washdown areas.
  • Chemical plant – WIEGMANN push button enclosures (e.g., 22mm or 30mm) for local control stations in hazardous indoor areas.
  • Building automation – WIEGMANN console enclosures (e.g., NEMA 12/13) for housing HVAC control systems in commercial buildings.

Frequently asked questions

Common questions about WIEGMANN from 3G Electric.

What NEMA ratings are available for WIEGMANN enclosures?

WIEGMANN enclosures are available in a range of NEMA ratings, including NEMA 1 (indoor general purpose), NEMA 12 (indoor dust and dripping water), NEMA 13 (indoor dust and oil), NEMA 3R (outdoor rain and sleet), NEMA 4 (indoor/outdoor washdown), NEMA 4X (corrosion-resistant), and NEMA 6P (submersible). Specific models may combine multiple ratings, such as NEMA 12/13/3R/4, to cover diverse environments. Always verify the rating against your application's exposure to dust, water, or chemicals.

What materials are used in WIEGMANN enclosures?

WIEGMANN enclosures are constructed from carbon steel, stainless steel, or fiberglass. Carbon steel enclosures are typically powder-coated or painted for corrosion resistance and are suitable for indoor or dry outdoor environments. Stainless steel enclosures offer higher corrosion resistance for washdown or chemical-exposure areas. Fiberglass enclosures are non-metallic, lightweight, and resistant to corrosion, making them ideal for submersible or harsh outdoor conditions.

What is the difference between WIEGMANN push button enclosures for 22mm and 30mm operators?

WIEGMANN push button enclosures are designed to accommodate either 22mm or 30mm diameter operators, such as push buttons, pilot lights, or selector switches. The enclosures are available with varying numbers of holes (e.g., 3, 6, 9 holes) and are typically made of carbon steel with a NEMA 12 rating for indoor dust and water droplet protection. The choice depends on the operator size and the number of control devices needed in the application.

Are WIEGMANN enclosures suitable for outdoor or washdown environments?

Yes, WIEGMANN offers enclosures rated for outdoor and washdown environments. Models with NEMA 3R, 4, or 4X ratings are designed for rain, sleet, hose-directed water, and corrosion. For example, the steel washdown enclosure (MPN N412241610C) is rated NEMA 12/13/3R/4, making it suitable for both indoor dust and outdoor washdown conditions. Fiberglass submersible enclosures (e.g., MPN HW-J181617XD) are rated NEMA 6P for temporary submersion.

What interior mounting panels does WIEGMANN offer?

WIEGMANN interior mounting panels, also called back panels, are steel panels used to mount components inside enclosures. They are available in various sizes, such as 33 in x 27 in (MPN NP3630) or 60 in x 44 in (MPN WA72P48F1), with finishes like powder coating or painting. These panels provide a flat surface for installing DIN rails, terminal blocks, or other equipment, and are designed to fit specific WIEGMANN enclosure models.

How do I select the correct WIEGMANN enclosure size for my application?

Selecting the correct WIEGMANN enclosure size involves determining the dimensions of the equipment to be housed, including clearance for wiring and heat dissipation. WIEGMANN enclosures are available in standard sizes, with overall heights, widths, and depths specified in inches (e.g., 36 in x 42 in x 12 in). Interior mounting panels can be used to maximize space. Refer to the enclosure's internal usable dimensions and NEMA rating to ensure it meets your environmental and spatial requirements.
