Designed to switch the traditional thermal bimetal safety gadget this digital model is way extra correct and longer lasting than something used earlier than. Newelec’s LA Collection is designed to be user-friendly with just one setting and consists of an built-in present transformer that permits conductor cables to run via it carrying as much as 250A.
The relay has management panel mounded fault indication LEDs which might be latched for overload, part loss and unbalanced load journeys. Each time the thermal capability of the motor has not recovered to a suitable worth, makes an attempt at resetting the relay can be met with a blinking fault LED that may subsequently robotically extinguish on completion of the cooling off interval.
The manufacturing unit set thermal curve class is 15 seconds and the unbalanced hundreds detection threshold is about at a most of 20% between phases. When used at the side of a mechanically and electrically interlocked cubicle door, the journey indication can be briefly misplaced till the provision energy is restored to the relay.
Alternatively the relay could also be fitted with a everlasting Nicad battery that retains all LEDs practical when there’s a lack of auxiliary energy provide.Safety Options:
* Thermal Overload Safety
* Locked Rotor Safety
* Working Stall / Jam Safety
* Unbalanced Present / Single Phasing
* Fail-safe Journey Relay Configuration
* Secure Operation with VSD / Gentle Starters
* No further CTs as much as 250 Amps
* Descriptive Fault Indication LEDs
* Indication and Journey Take a look at Facility
Typical Purposes
Pump motor
Thermal motor safety inside Class 5 Sizzling curve
Compressor motors with cyclic loading
