What is ELCB?
TONGOU provides a high-quality earth leakage circuit breaker(ELCB). It is used for preventing leakage. It has the wire end that the human body touches the power supply, that is, the live wire. When someone is leaked, ELCB will cut off the power supply within 0.1s to prevent further electric shock. It can only detect the earth’s fault flowing back to the main ground wire.
ELCB is suitable for low-voltage power networks with transformer neutral point ungrounded and low-voltage distribution systems with transformer neutral point grounded. It has two section protection functions of overload long time delay and short circuit instantaneous action. It can also be used with leakage devices, measurement, electrical operation and other module units. In low voltage distribution systems, it is often used as a terminal switch or branch switch. It replaces the fuse and knife switch commonly used in the past.
