Motor Overheat Protector GRB series

Application Field: GRB overheat protector is designed as a matching for PTC thermistor of MZ6. When the temperature of the motor coil( or some point on the coil) is over heat, PTC resistance rise. The signal transmits to GRB overheat protector, making a transition in the protector relay. Then the main current cut off to protector the motor. The Product Sells Point: * Advanced technology * Safety and steady * High reliability * Energy Conservation(self consumption power is 0.8VA) * The shut down temperature can be precisely worked out.   Key Specifications/Special Features: working voltage: 24V/AC/DC 110V/AC 220V/AC voltage tolerance: +/-20% frequency: 50-60Hz consumption power: less than 0.8VA ambient temperature: -30~70C contact rate: 7A action resistance: single: 1000 ohm * (1+/-10%)                          triple: 3000 ohm * (1+/-10%) reset resistance: single: 500~600 ohm                         triple: 1500~1800ohm No.of connecting PTC thermistors: 1~9pcs weight: 0.20Kg   Third Party Certificates: Product Sample Availability Policy: to be informed Order Lead Times(Days): 7-15 days Minimum Order Quantity: no
