Monitoring Relays
3RN1 Thermistor Motor Protection
For PTC sensors
3RN10 62 tripping units for multiple motor protection
Up to 6 sensor circuits can be connected to the 3RN10 62
tripping unit, all of which act on one output relay. The
simultaneous protection of several motors (up to 6) is an
advantage for multi-motor drives (e.g. if one motor is
overloaded, all the other motors of the drive will be shut down).
Apart from the red LED TRIPPED, which signals the switching
status of the tripping unit, an LED is assigned to each sensor
circuit which indicates the sensor circuit that has responded.
Unused sensor circuits must be short-circuited.
The reset response of the 3RN10 62 tripping units can be
changed from manual RESET to automatic RESET by linking
terminals Y1 and Y2. Remote RESET is implemented by
connecting an external pushbutton with a normally-open
function.

Safe electrical isolation
All circuits (outputs, control circuits, sensor and RESET circuits)
of the multifunction tripping units 3RN10 13-1BW10 and
3RN10 13-1GW10 (wide voltage range, monostable output relay
and screw-type terminals) are safely isolated from each other
up to a rated voltage of 300 V according to DIN VDE 0100
Part 410/EN 60947-1.
