500V Industrial AC Voltage Specification

Feature & Principle

500V AC belongs to low voltage range. Compared with 400V system, it can reduce the operating current under the same power. Electrical components under this voltage grade need to meet higher dielectric strength and creepage distance requirements. It is often used as the input voltage of general inverter and high-power three-phase motor, and matched with 380–500V wide voltage grade electrical equipment.

Specifications

Voltage: 3AC 500V Voltage tolerance: ±10% Frequency: 50Hz / 60Hz Insulation level: Matched with 690V grade components Application: VFD, three-phase motor, soft starter, distribution circuit Certification: CE

Components & Diagnostics

Power semiconductor, contactor, fuse, insulated cable. Common faults: insulation breakdown, creepage discharge, component overvoltage damage.
