Product Overview
Our 80A three-phase clearance connector is a high-performance, safety-focused component designed for medium commercial three-phase metering systems. This connector is engineered to meet the strictest utility and electrical safety standards, with optimized electrical clearance and creepage distance, ensuring superior insulation and protection against electrical arcing and short circuits.
Target Application: Medium Commercial Buildings
This 80A connector is specifically designed for medium commercial buildings, retail stores, restaurants, and light industrial facilities, where the electrical load is higher than residential systems but lower than heavy industrial installations. Common applications include:
Office buildings
Retail stores and shopping centers
Restaurants and hospitality facilities
Light manufacturing facilities
Agricultural facilities with medium-power electrical needs
It is optimized for use with standard 80A three-phase meters, providing a seamless, compliant connection that ensures accurate metering and reliable operation.
Core Engineering Specifications
To meet the strict requirements of utility bidding and electrical safety standards, this connector features the following key engineering specifications:
- Rated Current: 80A continuous duty
- Rated Voltage: 400V AC, three-phase
- Electrical Clearance: ≥ 8mm, meeting IEC 60947-1 standards for low-voltage electrical systems, providing superior protection against electrical arcing and short circuits between live parts.
- Creepage Distance: ≥ 12mm, ensuring that the surface of the insulation material provides adequate resistance to leakage current, even in humid and contaminated environments.
- Dielectric Withstand Voltage: 2.5kV AC for 1 minute, with no breakdown, meeting utility safety standards.
- Insulation Resistance: > 100MΩ at 500V DC, ensuring complete electrical isolation.
- Temperature Rise: < 45K at rated current, ensuring stable performance under continuous load.
