Notes
1)
Ambient air temperature: open and enclosed operating range to IEC/EN 60947, PTB: -5°C to +50°C
2)
Rated operational current: Making and breaking conditions to DC-13, L/R constant as stated
3)
See overlay “Fuses” for short-circuit rating time/current characteristic (please enquire)
4)
Terminal capacities auxiliary and control circuits, solid, flexible with ferrules: With connection of 2 conductors only the following combinations are
permissible: 0.5 and 0.75 mm², 0.75 and 1 mm², 1 and 1.5 mm²
5)
Safe isolation: Up to 240 V depending on contact assignment between mains and outputs no potential isolation to thermistor and summation current
transformer input and current sensor (neighbouring contacts: U
s
= 127 V)
6)
Rated operational current AC-15: contacts 95/96 and 97/98 3 A (contactor control), contacts 05/06 and 07/08 1.5 A (auxiliary contacts)
7)
Overload relay main contact setting range: setting range dependant on current sensor
8)
Main contacts terminal capacity solid and stranded conductors with ferrules: When using 2 conductors use identical cross-section
Ambient temperature open and enclosed: limited readability of the LCD display at < -15°C
