Why you use ELR?
An ELR is terminology used in fire alarm systems. It stands for End of Line Resistor. It is used as a load on individual fire alarm circuits. This load draws a small current that is monitored by the alarm panel. What the panel is monitoring for is open circuits in break glass and bell circuits. If the current is non existent then it means that one of the fire circuits is opened, out of service and non operational. In the alarm panel a relay is de-energized and a trouble alarm is activated to bring attention to the problem. Once the problem is repaired the current again flows through the ELR and the trouble relay resets.

What is the difference between elcb 30mA and elcb 300mA?
An ELCB is an Earth Leakage Circuit Breaker and is a device used for safety purposes to detect stray voltage or current on a metal enclosure in order to prevent shock. The two types of ELCB are Voltage-operated and current-sensing protection. The difference between a 30mA ELCD and a 300mA ELCB is that the 30mA version will have a much higher level of sensitivity, tripping the device is a much lower current.
