K8AK-TS/-PT Temperature monitor
Thermistor motor protection relay
The K8AK-TS is the temperature monitoring relay based on the thermistor detection and can protect the motor from overheating.
The K8AK-PT gives further functionalities such as temperature, 3-phase sequence and loss monitoring and contributes to the overall safety 3-phase motor‘s operation.
• DIN 22.5-mm-sized K8AK-PT relays
• Side-by-side mounting of K8AK-PT relays
• Specially designed for internal motor monitoring, no setting required
• Test/Reset button for confirmation of output operation
• Monitoring also performed for thermistor disconnections and short circuits
• Manual or automatic resetting with the same relay
