• 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 ca*** 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 ***d 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.
