Overview
The Single Phase Nine Meter Terminal is a high-density wiring block purpose-built for centralized metering in multi-tenant residential buildings. It brings together nine fully independent single-phase meter connections in one space-saving assembly, delivering standardized, secure, and consistent power distribution for large apartment blocks, urban village upgrades, and community housing projects. By consolidating the work of nine individual terminal strips, this unit dramatically shrinks panel real estate, streamlines cabling, and lowers total installed cost. Each meter circuit incorporates its own dedicated bypass, permitting live meter exchange without disturbing neighboring units - a critical advantage for utilities, facility managers, and electrical contractors executing large-scale grouped metering rollouts.
Why This Terminal Delivers
- Nine fully segregated metering channels prevent any crosstalk or fault propagation between apartments.
- Space-optimized layout reclaims roughly 50% of panel area compared to installing nine separate blocks, enabling smaller enclosures and reduced sheet metal cost.
- Heavy-duty main busbar - a 200 A copper backbone with low temperature rise - effortlessly carries the combined load of all nine meters, even at full demand.
- Per-position live swap - each channel has an independent bypass circuit, allowing any single meter to be pulled and replaced without interrupting supply to the remaining eight dwellings.
- Minimal thermal stress - initial contact resistance held at or below 0.35 mΩ keeps connections cool, safeguarding meters against heat-induced failure.
- Robust insulation - dielectric withstand exceeding 2.5 kV guarantees reliable performance during voltage transients.
- Visual verification - a transparent, laser-engraved cover provides instant wiring confirmation and torque inspection without removing any parts, cutting fault-finding time by up to 60%.
- Universal mechanical fit - standard mounting hole patterns and DIN rail compatibility enable drop-in installation into most residential meter cabinets without panel rework.
- Adaptable current ratings - each position supplies 60 A as standard, with an 80 A option for higher-consumption scenarios such as electric vehicle charging.
- Field-friendly wiring - a single main feed point and organized internal busbar distribution simplify large-scale terminations and slash on-site wiring time by about 45%, directly reducing labor expense for volume deployments.
- Vibration-proof clamping - self-locking crimp contacts maintain strong, stable pressure over time, resisting loosening from mechanical vibration.
- Tool versatility - universal screw heads accept both flat-blade and Phillips drivers, speeding up connection work.
- Built to last - molded from high-grade flame-retardant PA66 (UL94 V-0), the housing resists aging, impact, and temperature swings from -40 °C to +85 °C.
