Part number
Product description
The electronic current transformer STWA1LH monitors alternating currents 2 ... 20 A. For lower currents, the monitored wire can be led multiple times through the transformer. Used in the secondary circuit of transformers (e.g. 100/5 A), it is possible to monitor higher currents. The STWA1LH directly switches alternating voltage up to AC 230 V / 0,35 A.
- Control of ventilations or suction plants
- Control of valves at suction plants in the woodworking industry
Features
- Monitoring of alternating current up to 20 A
- Response value adjustable 2 ... 20 A
- Two-wire contact (voltage supply through output)
- Operating voltage AC 24 ... 230 V
- Transformer, ø 11 mm
- Space-saving, easy mounting
- Potential separation between monitored current circuit and switch output
