Switches & Modular Apparatus Appleton Group

The EDS Series factory sealed tumbler switches are specifically designed for environments classified as hazardous due to the presence of ignitable vapors, gases, or combustible dusts. These switches are particularly suitable for use in chemical and petrochemical plants, refineries, and other process industries. Constructed with a malleable iron body and covers, these switches feature a sealing chamber made from copper-free aluminum in select models. The handle is made from nylon 6/6, while the optional nameplate mounting bracket is crafted from corrosion-resistant stainless steel, providing durability and facilitating easy circuit identification without the need for costly field modifications. The switches come with a triple-coat finish comprising zinc electroplate, chromate, and epoxy powder coat, enhancing their resistance to harsh environmental conditions. They meet rigorous standards, including NEC and CEC certifications, allowing operation in Class I, Division 1 and 2 (Groups B, C, D) as well as Class II and III environments.

The Unicode 2 Series 16 Amp switches are engineered for enhanced safety in industrial applications. These switches facilitate circuit control and selection, making them ideal for integration with contactors or magnetic starters for motor management. With compliance to NEC, CEC, ATEX, and IECEx standards, the devices are rated for Class I, Division 2 and Zone 1 environments, ensuring reliable operation in hazardous conditions. Constructed with a polyamide body and silver alloy contacts, these switches operate effectively across a broad temperature range, from -55 °C to +80 °C (-67 °F to +176 °F) for both NEC and CEC environments, as well as ATEX and IECEx specifications. Handles are rated for -20 °C to +55 °C (-4 °F to +131 °F), providing durability and functionality in various operational settings.

The nonmetallic tumbler switch, identified as PN N1DC75F3W, is specifically engineered to mitigate the risk of arcing in environments where flammable gases, vapors, or combustible dust may be present. This switch is suitable for use in various industrial settings, including chemical and petrochemical plants, as well as refineries.Constructed from 30% glass-reinforced thermoplastic polyetherimide, the switch features Teflon™ coated stainless steel cover bolts and Mylar™ nameplates, ensuring durability and resistance to corrosion. The design includes a nameplate mounting bracket that simplifies the identification of circuits, eliminating the need for field modifications such as drilling or tapping.This unit meets stringent safety standards, certified under NEC for Class I, Division 1 and 2, Groups C and D, and NEMA ratings of 3R, 4X, 7CD, and 12, ensuring reliable performance in demanding conditions.
