product description
STWA1 current transformer (for current detection)
STWA1 for reliable machine operation detection: The inductive current transformer detects alternating current in a conductor routed through it and supplies the signal to compatible ZIEHL STW-series current relays. No intervention in the machine control system is required.
The conductor is simply passed through the opening of approximately 11 mm. The STWA1 requires no separate supply voltage, making it straightforward to retrofit. One current transformer is required per monitored machine or conductor.
