2 pole 100a earth leakage circuit breaker
A specific product!
A 2-pole 100A earth leakage circuit breaker (ELCB) is a type of electrical protection device designed to detect and interrupt an earth fault current in a electrical circuit. Here's a breakdown of the key features:
2-pole: This means the breaker has two separate poles, each capable of carrying a current of up to 50A. This is typical for a 230V AC system, where each pole carries half the total current.
100A: This is the maximum current rating of the breaker, which means it can interrupt a fault current of up to 100 amperes.
Earth leakage circuit breaker (ELCB): An ELCB is a type of residual current device (RCD) that detects earth leakage currents, which can occur when a person or object comes into contact with a live electrical conductor. The breaker is designed to trip (interrupt the circuit) when it detects an earth leakage current exceeding a certain threshold (typically 30mA).
Key characteristics:
- Sensitivity: The breaker is designed to detect earth leakage currents as low as 30mA.
- Response time: The breaker is typically designed to respond quickly to earth leakage faults, with a response time of around 10-30 milliseconds.
- Interrupting capacity: The breaker is capable of interrupting a fault current of up to 100A.
- Operating voltage: The breaker is designed to operate at a voltage of 230V AC, although some models may be rated for higher or lower voltages.
Applications:
- Residential and commercial electrical installations
- Industrial applications where personnel are at risk of electrical shock
- Areas prone to flooding or high humidity, where the risk of electrical shock is increased
Some popular brands:
- Schneider Electric (e.g., Residual Current Breaker (RCB) series)
- ABB (e.g., Residual Current Device (RCD) series)
- Siemens (e.g., Residual Current Breaker (RCB) series)
- Legrand (e.g., Residual Current Breaker (RCB) series)
Please note that the specific features and characteristics of a 2-pole 100A earth leakage circuit breaker may vary depending on the manufacturer and model. It's essential to consult the product datasheet or manufacturer's documentation for specific information on the breaker's performance and application.
