Project Description

LR9 iec Thermal overload relay operation unit sizing

LR9 iec Thermal overload relay operation unit sizing work with ac contactor up to 630A. And this thermal overload relays are suitable for overload protection of AC motor operated on 8-hour duty or uninterrupted duty.The overload protected AC motor is of  frequency 50Hz,voltage up to 660V and current up to 40A.  There are several functions such as phase –failure protection,temperature compensation,ON/OFF indication and manual and automatic reset.The relays comply with IEC292-1 standard.
