ASKD 21.3 - Dreiphasen-Stromwandlersätze
The plug-on current transformer ASKD 21.3 - three-phase current transformer sets is a compact, high-precision low-voltage current transformer of the proven AS series, specially developed for use in power distribution, switchgear, meter panels and industrial measurement and monitoring systems.
Technical main features:- Type plug-on current transformer – three-phase current transformer set ASKD 21.3
- Primary conductor bore For round conductors up to max. Ø 21 mm (cable entry)
- Maximum operating voltage Um ≤ 0.72 kV
- Rated frequency 50–60 Hz
- Thermal rated continuous current Icth = 1.0 × Ipr (continuous current 1 × primary rated current)
- Thermal rated short-time current Ith = 60 × Ipr, 1 s
- Insulation class E
- Insulation test voltage 3 kV, 50 Hz, 1 min
- Mounting Foot and rail mounting possible, including insulating protective cap
The ASKD 21.3 stands out due to its very compact design as a three-phase current transformer set, high reliability and excellent linearity – ideal for applications where precise three-phase measurement is required at relatively low currents (e.g. smaller distribution boards, measuring stations, energy monitoring systems with moderate power requirements).
We will be happy to supply this model from stock at short notice or configure further variants of the AS series for you.
