The TRM Series, manufactured by Circutor, is a current instrument transformer that is used to determine the measurement of rotating electric currents. This transformer is especially compressed ...
Current: 1 A - 40 A
... a lower current so that it can be measured by the unit. In installations where the nominal current is not too high or a transformer has to be installed on the DIN rail.
Current: 100 A - 5,000 A
The most important features of these transformers are that they are "disassemblable". In other words, the whole installation does not have to be disassembled. Busbar dimensions: from 20 x 30 mm to 80 x 160 mm
Current: 40 A - 4,000 A
Type: bar entrance internal diameter: from 20.3 to 63 mm, depending on the type Busbar dimensions: from 25 x 5 mm to 30 x 100 mm DIN rail fixing accessory (Types TC5 and TC6) Secondary coding types .../5 A (on demand .../1 A. TC12 not available)
Current: 5 A - 1,500 A
- Needs an output power supply of 7.5...36 V dc - Primary current: from 5 to 1500 A ac, depending on the type - Secondary current: 4..20 mA - Internal diameter: from 20 to 44 mm, depending on the type - Busbar dimensions: ...
Current: 2.5 A - 1,500 A
Built-in internal output power supply Needs an auxiliary power supply of 230 V ac Primary current: from 2.5 to 1500 A ac, depending on the type Secondary current: 4..20 mA Internal diameter / Busbar dimensions: from 35 to 105 mm
Current: 5 A - 400 A
... unit. In installations where the nominal current is not too high or where the current requested from the secondary power transformer does not exceed 10 V·A.
Current: 100 A - 4,000 A
... current so that it can be measured by the unit. In installations where the electrical supply can be interrupted to install transformers and a high accuracy is required.
Current: 5 A
Electric power: 0.015 kVA
Accuracy class 0.5 Power 15 V·A The transformers added must have the same ratio No input must be without a connection
Electric power: 0.025 kVA
Accuracy class 1 Power 25 V·A Used in AC electricity lines to obtain a lower voltage in the secondary than in the primary, so that it can be measured by electronic equipment
