    General Information

    Standards

    CEI 85, EN 600051, IEC 414, VDE 0410, UNE 21318, DIN

    43780, IEC51.

    Cases

    • ABS & P.C material.

    • Protection degree (CEI 70-1, IEC 529) IP 52 for the case.

    • Protection degree (CEI 70-1, IEC 529) IP 00 for terminals.

    Accuracy class

    All the instruments are manufactured in 1,0; 1,5; 2,5 accuracy class.

    Overloads

    All amperometric circuits support an overload of 1,2In continuous and 10In for 5 seconds. All voltmetric circuits support an overload of 1,2Vn continuous and 2Vn for 5 seconds.

    Working voltage:

    650V

    Test voltage:

    2000V-50Hz / 60Hz, for 1 minute.

    Insulation

    Insulation reference voltage 0,6 KV.

    Working temperature

    20°C (± 10°C): working range between -25°C and + 55°C.

    Vibrations

    ± 0.25 mm amplitude at 50 Hz/60Hz (CEI 50-6, IEC 68-2-6).

    Humidity

    Ambient relative humidity 85% without condensing, with 35°C temperature for max. 60 days per year. Yearly average humidity must not be higher than 65% (DIN 40040).

    Tropical version

    95% relative humidity, for a maximum of 30 days per year.

    Mounting position

    The normal execution of our instruments is for vertical mounting. If other mounting positions are known in advance, please indicate the angle of inclination when ordering.

    Scales

    The full scale deflections correspond to DIN 43701.

    The scale divisions correspond to DIN 43802.

    Maximum Demand Meters

    These have a bimetallic measuring system. The bimettallic system drives a red pointer to mark the maximum current used. The range of the meter is 6A and 1,2A. The meter works off a-/5A or -/1A, C.T. with a 20% overload. The red maximum demand pointer is resetable by a manual knob which can also be sealed. The response time is 15 minutes.

    Internal Consumption: approximately 2,5VA
