HAMMOND
Frequently asked questions
Common questions about HAMMOND from 3G Electric.
What NEMA ratings are available in Hammond steel dust-tight enclosures?
Hammond steel dust-tight enclosures are typically rated NEMA 12 and 13. These ratings indicate protection against dust, dirt, and non-corrosive liquids such as dripping water and oil seepage. Some models may also carry NEMA 3R or 4 ratings for outdoor use. The specific rating depends on the model and construction. For example, the 1418MR8 is rated NEMA 12/13, while the EJ664LG is rated NEMA 12/13/3R/4 and IP66. It is important to verify the rating for each enclosure to ensure it meets the environmental conditions of the installation.
What is the difference between Hammond's 1418 and 1422 series enclosures?
The Hammond 1418 and 1422 series are both steel dust-tight enclosures, but they differ in size and configuration. The 1418 series includes wall-mount and floor-standing models with various dimensions, such as 30 x 36 x 8 inches (1418MR8) and 48 x 30 x 10 inches (1418R10). The 1422 series typically includes larger floor-standing enclosures, such as the 1422F20F measuring 72 x 72 x 21 inches. Both series offer NEMA 12 or 12/13 ratings, solid hinged covers, and options for mounting panels. The choice between them depends on the required internal space and mounting method.
Are Hammond stainless steel enclosures suitable for outdoor use?
Yes, Hammond stainless steel enclosures, such as the EN4SD202010SS, are rated NEMA 12/13/3R/4/4X, which makes them suitable for indoor and outdoor use. The 304 stainless steel construction provides corrosion resistance, and the 1/4-turn latch ensures a secure closure. These enclosures are designed to protect against dust, water, and corrosion, making them appropriate for washdown environments and outdoor installations. However, the specific suitability depends on the environmental conditions and the rating of the particular model. Always confirm the NEMA rating and material compatibility with the application.
What closure methods are available for Hammond enclosures?
Hammond enclosures are available with several closure methods, including clamps, latches, quarter-turn latches, and handles. For example, the 1418MR8 uses clamps, the EN4SD202010SS uses a 1/4-turn latch, and the 1418TW18 uses a handle. The choice of closure affects access speed, security, and sealing performance. Clamp closures often provide a tight seal for dust-tight applications, while quarter-turn latches allow quick access. Handles are common on larger enclosures for easier opening. The appropriate closure depends on the frequency of access and the required protection level.
Can Hammond enclosures be modified with knockouts or additional panels?
Many Hammond enclosures are available with or without knockouts, and some include mounting panels. For instance, the 1418MR8 includes a panel but does not include knockouts. Knockouts can often be added as a modification, or they may be present on specific models. Mounting panels are available for many enclosures to facilitate component installation. 3G Electric can assist with selecting enclosures that meet specific modification requirements, including custom knockouts, panel sizes, and other alterations. It is recommended to consult with 3G Electric for availability and lead times for modified enclosures.
What are the typical applications for Hammond washdown enclosures?
Hammond washdown enclosures, such as the EJ664LG, are rated NEMA 12/13/3R/4 and IP66, making them suitable for environments where equipment is regularly cleaned with water or where dust and moisture are present. Typical applications include food and beverage processing, pharmaceutical manufacturing, and industrial washdown areas. These enclosures protect electrical controls and instrumentation from water spray, dust, and corrosion. The IP66 rating indicates protection against powerful water jets, ensuring suitability for high-pressure cleaning. The steel construction with a solid cover and latch closure provides durability and secure sealing.
