Leakage current control device for construction sites

Summary

This smart safety device prevents electric shock and electrical fires by limiting leakage current generated at construction sites to 5mA or less. (KS C IEC TS 60479-1: Effects of Electric Current on Humans and Livestock)

Key Features

Safe power supply even in case of unavoidable accidents

Provides safe power without risk of electric shock to human body even in situations where power is cut off due to ground fault, leakage, or flooding.

Real-time insulation status monitoring

Automatically detects and notifies insulation loss in real time while the line is live, preventing electrical accidents such as ground faults and leakage currents before they occur.

Application to construction sites

Mobile leakage current control devices are newly designated as part of the 2025 Safe Workplace Creation Support Project, enabling government support and industrial safety and health management expenses for construction headquarters and on-site sites.

Meeting legal and technical standards

Technology that complies with construction site electrical equipment standards such as KSC IEC 60364-7-704 and has been proven effective in preventing electric shock accidents.

Differences from existing equipment

Conventional temporary power unit
Failure to meet electrical installation technical standards due to risk of electric shock, fire, or death Illegal
VS
Intelligent Temporary Power Team
Equipped with electric shock and fire prevention technology, eligible for government certification and subsidies Legal Recommended Use
In other words, the intelligent temporary power unit is a device that eliminates the illegality of conventional temporary power units and simultaneously secures legality and safety.
