Product catalog summary
Features of EJB Series Boxes
The EJB series boxes are versatile enclosures used as junction boxes with or without terminals and for installing various electrical equipment such as circuit breakers, signals, disconnectors, remote control switches, and transformers. They can be customized by drilling and threading according to customer specifications. The boxes are made from copper-free aluminum alloy with stainless steel cover bolts and hinges, and feature internal and external earth screws. They are coated with Ral 7035 epoxy paint and include mounting brackets, an internal frame, anticondensation coating, and a drain and breather valve.
Specifications
The EJB enclosures are suitable for use in hazardous zones 1, 21, 2, and 22, with temperature ratings ranging from -50°C to +55°C. They comply with ATEX, IECEx, INMETRO, and GOST R standards, ensuring safety and reliability in explosive environments.
Selection Charts
Two types of enclosures are available: those with ribbed lids and those with solid lids. The ribbed lid enclosures offer flexibility, while the solid lid enclosures accommodate more control and signaling devices or specific handle placements.
Push-Button Options
The document details various push-button options, including normal, double, reset, illuminated, key-operated, and emergency stop push-buttons. These buttons come with standard 10A 600V contacts and are available in multiple colors. Emergency stop buttons feature different release mechanisms, such as twist, pull, and key-to-release.
Indicator Lights and Handles
Indicator lights are available with 3W lamps or high-brightness LEDs, offering a choice of five lens colors. Various handles are described for cam switches, rotary switches, and circuit breakers, including quick-connect, padlockable, and wall-mounting options.
