- ZIEHL PTC-resistor relays protect motors, transformers, machines and equipment against thermal overload. With ZIEHL PTC Sensors MINIKA ® applied they offer best solutions for nominal response temperatures 60°C…180°C.
- ZIEHL PTC-resistor relays are designed for PTC-sensors according to DIN 44081 and DIN 44082. Therefor sensor and relays are exchangeable. PTC-resistor sensors are suitable for the installation into windings of electrical machines, bearings and transformers as well as to monitor the temperature of liquid media, airflow and gases.
- 2 PTC-resistor sets, each 1...6 PTC resistors
- output relays 2 x 1 change-over contact (co)
- LEDs for operation and alarm
- electronic reclosing lock (disconnectable)
- integrated RESET-button
- link for external RESET
- automatic RESET at voltage recovery
- UL-Recognized Component
