DBX-5000 Type Single-Phase Electricity Meter Box
DBX-5000 type meter box is a terminal distribution enclosure designed for installing single-phase electric energy meters (220V). The component mounting plate of the DBX-5000 utilizes an adjustable track with movable blocks, enabling a modular approach to internal component installation — DIN-rail devices, terminal blocks, and metering equipment can be positioned with precision and reconfigured without drilling or plate modification.

Key Features
- Adjustable Track Modular Mounting System: The innovative mounting plate with adjustable track and movable blocks allows precise positioning of all internal components — meters, DIN-rail MCBs, terminal blocks, and neutral/earth busbars — without drilling, tapping, or plate replacement, enabling rapid reconfiguration for different meter types and distribution layouts
- Flexible Component Arrangement: Components can be added, removed, or repositioned by simply sliding the movable mounting blocks along the track — accommodating changes in meter type, protective device configuration, or wiring requirements without enclosure modification
- Secure Revenue Metering: Dedicated sealable meter compartment with transparent reading window and utility-standard locking maintains metering security and tamper evidence while enabling convenient meter reading
- Modular Design Philosophy: Standardized mounting interfaces and component spacing simplify assembly, reduce installation time, and ensure consistent build quality across multiple enclosure installations
Applications
- Residential apartment buildings — individual apartment revenue metering
- Residential houses and villas — household electricity metering
- Commercial retail outlets — tenant metering and billing
- Small office buildings — individual consumer metering
- Dormitories and staff quarters — per-occupant electricity billing
