Door with Lock for Power Distribution Panels

Product Specifications

Technical details and manufacturing context for Door with Lock

Definition

This door with integrated locking mechanism is a component designed for power distribution panels. It serves as the primary access point to internal electrical components while preventing unauthorized entry. The door maintains the panel's structural integrity, provides protection against environmental contaminants, and ensures operator safety by restricting access to live electrical parts. Constructed from materials such as galvanized steel, stainless steel, or powder-coated aluminum, the door is available in various sizes and thicknesses to suit different enclosure requirements. Key parameters include rated voltage up to 400 V AC, rated current from 630 to 2500 A, degree of protection from IP54 to IP65, and operating temperature range from -25°C to 55°C, all referencing IEC 61439 and IEC 60529 standards. The door features a 3-point locking mechanism with a cylinder lock, and optional padlock capability. Surface treatment is typically powder coating in RAL 7035, with other RAL colors available. The door dimensions range from 400 to 1200 mm in width and 600 to 2000 mm in height, with a thickness of 1.5 to 2.0 mm, and weight from 15 to 60 kg. The material is cold-rolled steel (DC01) per EN 10130. This component is type-tested to IEC 61439. For specific applications, verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The door operates on a hinged or sliding mechanism that allows controlled access to the panel interior. The integrated lock mechanism, typically key-operated, combination, or electronic, secures the door in the closed position, preventing unauthorized opening. When properly closed and locked, the door maintains the panel's IP rating and safety certifications. The 3-point locking system distributes force evenly to ensure a tight seal and enhanced security. The door's construction and materials contribute to its structural integrity and environmental protection. For proper operation, ensure the door is correctly aligned and the lock engages fully. Regular inspection of the hinge, seal, and lock mechanism is recommended to maintain performance and safety.
