    SIRIUS 3RN10 00 // 62 thermistor motor protection relay


    3RN10 00: Compact, low-cost unit, with LED 'tripped' indicator and 1 changeover relay contact; reset is automatic when sensor has cooled down; control and signalling voltages should have the same potential; 3 voltage options - 24 VDC, 110 VAC or 230 VAC
    3RN10 10: Standard unit with 1 N/O and 1 N/C contact; 2 'Tripped' and 'Ready' LEDs; multi-voltage 24 → 240 VAC/DC
    3RN10 13: Multi-function unit with 2 changeover contacts; detects open or short-circuited sensor and has auto or manual reset options; multi-voltage 24 → 240 VAC/DC
    3RN10 22: 2-sensor monitoring for ALARM and TRIP conditions; alarm operates 1 N/O contact with additional changeover contact for TRIP condition; multi-voltage 24 → 240 VAC/DC
    3RN10 62: Multi-sensor evaluation relay, able to monitor up to 6 PTC sensors; Overtemperature of any one sensor will cause the output contact (1 N/O + 1 N/C) to operate; multi-voltage 24 → 240 VAC
    3RB10 65. Solid state relay with a current rating of 200 A

    3RN1 Series thermistor relays are a range of thermal protection devices which, when used in conjunction with external PTC thermistors, offer temperature monitoring of electrical drives, transformers and other critical components such as bearings. 3RN1 Series products operate on the principle of closed-circuit current and are therefore self-monitoring in the event of a wire breakage. All devices with the exception of the 3RN10 62 are 22.5 mm wide. The 3RN10 63 is 45 mm wide.
