FAQ
Q1. What is an explosion-proof junction box used for?
A1. It houses terminal blocks and provides a secure enclosure for connecting, branching, and terminating electrical conductors in hazardous-area installations. The selected model must match the required hazardous-area classification, Ex marking, IP rating, and environmental conditions.
Q2. What terminal configurations are available?
A2. Terminal type, quantity, and rated current are selected according to conductor cross-section and circuit requirements. Available configurations depend on the enclosure dimensions and cable-entry arrangement.
Q3. Can the junction box be customized?
A3. Yes. The enclosure dimensions, terminal arrangement, number and positions of cable entries, thread type and size, and surface finish can be specified according to project requirements, subject to technical confirmation.
Q4. What information is required for a quotation?
A4. Please provide the required hazardous-area classification, enclosure dimensions, number of circuits, conductor cross-section, rated voltage and current, cable-entry details, quantity, and documentation requirements. We will review your specifications and respond within 24 hours.
