Product Introduction

ETL1-63B Type B Residual Current Circuit Breaker (RCCB) suitable for 230/240V (1P+N) or 400/415V (3P+N) power systems, with a rated current up to 63A. Designed to detect AC leakage currents, pulsating DC leakage currents, smooth DC leakage currents, composite waveform leakage currents, and high-frequency leakage currents up to 1kHz.

 

When human electric shock occurs or circuit leakage current exceeds specified values, the circuit breaker instantaneously disconnects the faulty power supply to protect personnel and electrical equipment. It can also serve for infrequent circuit switching operations under normal conditions.

 

Applications

 EKL1-63B Type B RCCB is designed for a wide range of applications, including:

Electric Vehicle (EV) Charging Stations: Provides reliable protection for EV chargers where DC leakage currents are common.

Solar Power Inverter Systems: Ensures safety in renewable energy installations with high-frequency components.

• Industrial Machinery: Protects equipment with variable frequency drives or inverters.

Medical Equipment: Ideal for healthcare facilities requiring sensitive leakage protection.

Data Centers and IT Infrastructure: Safeguards critical systems with DC microgrids.

Elevator and Escalator Systems: Ensures safe operation in modern building infrastructure.

Welding Equipment: Provides protection in workshops with high DC leakage risks.

Laboratory and Research Facilities: Ensures safety in environments with advanced electrical equipment.

Smart Buildings: Perfect for modern buildings with DC microgrids and high-frequency devices.
