Protection relays detect abnormal operating conditions in an industrial system and may trigger an alert or isolate the offending device from the system. Common detection functions include; Arc-flash, temperature monitoring, ground fault, over-current, over-voltage, reverse power flow, over-frequency, under-frequency and phase loss, sequence or imbalance.
Function: Indicates the style and configuration of the device.
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Trip Range: Indicates the range over which a device’s monitoring threshold can be adjusted.
Delay Time: Describes a fixed or adjustable period of time after a monitored circuit exceeds some defined threshold that a device will wait before actuating its output.
Mounting Type: Indicates how the device is attached.
Termination Style: Selection of termination style used to connect the device to a system, such as screw terminals or wire leads.
Features: These are different capabilities or properties of the device such as an automatic reset or test button.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
