    Dear Sir,
    We presently use your CR5220-300 transducer.
    Normally, the current is no more than 250A.
    Sometimes, for a period of few seconds, the current rises approximately to 1000A.
    What will be the current output of the transducer when this occurs?
    Thank you.

    Dear Sir,

    The terminals are only rated for 600 amps. DO NOT USE THIS DEVICE ABOVE 600 AMPS.

    Dear Sir,

    The terminals are only rated for 600 amps. Arking can occur at 1,000 amps. Do NOT USE THIS DEVICE AVOVE 600 AMPS.


    Dear Tony,

    I do not understand your response. There are no exposed contacts here, so between which two points can arcing occur?

    We use DC current transducer (CR5220) with a 4-20mA output.

    Returning to my original question... How many mA will the output be if the current rises momentarily to approx. 1000A?
