DESCRIPTION
TP-88 500 /5A, Split core current transformers
Code: M70134.
- System: Single-phase
- Class 0,5 Power (VA): 2,5
- Class 1 Power (VA): 5
- Class 3 Power (VA): 15
- Measurement Range (A): 500/5
- Input current: 500/5 A
Open-core transformers that can measure current without having to interrupt the electric supply. In other words, the installation does not have to be dismantled in order to install them.
- Range: 100 to 5000 A
- Busbar dimensions: 20 x 30 mm to 80 x 160 mm
- The transformer certificate is attached.
APPLICATIONS
Converting a high nominal current to a lower current so that it can be measured by the unit. They have a split core and can be installed with no need to interrupt the installation’s power supply.
