EC / CC / BC analog panel ammeters and voltmeters for AC and DC, shunts
Country: Spain · Model: EC / CC / BC
The EC, CC and BC pointer panel ammeters and voltmeters for AC and DC have a basic accuracy class of 1.5 and cases of 48×48, 72×72, 96×96, 144×144 mm or modular for DIN rail. They give readings without auxiliary power, so they are suited to incoming and distribution boards, control panels, desks, and generator and marine boards.

Description
An electromagnetic system is used for AC, and a moving-coil magnetoelectric system for DC and for versions with a rectifier or converter. AC ammeters come as direct-connection with a 90° scale, with a variable scale for CT x/1 or x/5 A, with a 240° scale, with a 4-position selector switch, with a rectifier, and there are also milliammeters. Voltmeters are made as direct-connection, with a 3- and 6-position selector switch, with a 240° scale, and as rated-value instruments with an expanded zone near the rated value. DC instruments cover µA, mA, A, mV and V, and ammeters are connected through a 60 or 150 mV shunt. The range is supplemented by instruments with minimum and maximum contacts for signalling, maximum demand meters, and dual and differential voltmeters. The cases comply with IEC 61554, the scales with DIN 43701/43802, the test voltage is 2 kV 50 Hz 1 min, the case is IP52 (IP54 or IP65 to order), and the terminals are IP00 or IP20.
How to choose
Selection starts with the type of current and the connection method. On lines with current transformers an x/5 A or x/1 A ammeter with a variable scale is taken, so that after a CT replacement only the scale is changed, and for DC a shunt from the 10–4000 A range is added. If besides readings energy metering and harmonics are needed, a digital AHM1 / AHM3 or SNG96 is installed instead of a pointer instrument.

FAQ
What overload can panel ammeters and voltmeters withstand?
The voltage circuit withstands 1.2 Un continuously and 2 Un for 5 s, and the current circuit 1.5 In continuously, 5 In for 30 s, 10 In for 5 s and 40 In for 1 s.
Are these instruments suitable for marine boards?
Yes, there is a DNV (Det Norske Veritas) certificate, vibration resistance under VDE 0410 is 2.5g, shock resistance is 15g, the operating temperature is −25…+40 °C, and a tropical version under DIN 40040 is made to order.
What accuracy do DC shunts up to 4000 A have?
Shunts for 10–4000 A with a 60 or 150 mV voltage drop have an accuracy of 0.5 %, withstand 1.2 In continuously and are made to DIN 43703.
Which standards do the EC / CC / BC instruments comply with?
EN 60051, BS 89, EN 50081/50082, VDE 0410 and EN 61010; production is certified to ISO 9001:2015, and CE declarations exist for the EC, CC and BC series.
