Product description
The STWA1H current transformer is made to match the current-relays for recognition of AC-current and for controls for deducting plants type STW. Above app. 2 A the built-in LED lights and indicates a current. A current-relay type STW or a LED can be connected to the terminals.
The STWA1H has been designed for mounting in a switchgear cabinet. The housing can be fixed on a DIN-rail or with 2 screws. The maximum diameter of the monitored line is 11 mm. The current is only limited by the diameter that can be lead through the transformer. The electrical connection is made via screwless pluggable terminals.
- connection to current-relays type STW
- indication with LED from app. 2 A
- indication of shortest current-pulses
- Built-in resistor to protect LED
- no supply-voltage required
- electrical connection via screwless pluggable terminals
- plug-in current transformer (Ø 11 mm)
