Product type
An Earth Leakage Circuit Breaker (ELCB) is a safety device designed to prevent electric shock and electrical fires by detecting earth faults. It works by monitoring the electrical current flowing through the circuit and tripping the circuit when it detects an imbalance, indicating that current is leaking to the ground. ELCBs are typically made from durable plastic and metal components that house the electrical circuitry.
| Voltage rating | 230V to 400V |
| Current rating | 16A to 125A |
| Tripping sensitivity | 30mA to 300mA |
| Number of poles | 1-pole, 2-pole, 3-pole, 4-pole |
| Standards compliance | IEC 61008, IEC 61009 |
When selecting an Earth Leakage Circuit Breaker, consider the voltage and current ratings that match your electrical system. It's essential to specify the desired tripping sensitivity based on the application, as this affects the level of protection against electric shock. Additionally, check for compliance with relevant safety standards and certifications. Quantities may vary based on project size, so it's advisable to assess your needs before requesting a quote.
