Single phase and polyphase motors
Selectable Trip Class
Trip classes- 5, 10, 20 or 30 selectable by DIP switches field changeable reduces time and inventory suitable for light, normal and heavy starting conditions
Phase loss protection trips in less than 3 sec protects motor burn out and minimizes motor heating up
Phase unbalance trips based on trip class selected minimizes temperature rise of the motor on a asymmetrical 3-phase system
Ground fault trips 60% of motor current provides optimum system protection of motors against high resistance short circuits or ground faults due to moisture, condensation, damage of insulation or any other reason
Trip indicator visible-save time, faster to identify overload trip
Ambient insensitive-prevents nuisance tripping
No heaters required-saves cost and eliminates time for installation of heaters
Self-powered no outside source required-reduce cost for external power supply
FLA dial with wide adjustment 4:1 ratio provides wide range, reduces inventory
Self-protected in short circuit condition (when used with proper fuses or motor starter protector-unlike bimetal overloads, this eliminates replacement of the overload heaters after short circuit
Test button tests electronics tests the complete electronic functions including the trip mechanism increases up time
Thermal memory prevents re-starting motor when it is still hot
Conformally coated circuit board resists against environmental conditions
1NO-1NC contacts standard B600, R300 makes it easier for user to wire local contacts
Wide operating temperature range prevents nuisance tripping with temperature changes
Repeat accuracy <1% for more precise settings and reduced nuisance tripping
Removable terminal block terminal block can be removed without removing wires saves time for replacements
Automatic reset is 3 min after tripping, allowing motor to cool down before re-start, if manual reset is selected, overload can be reset immediately
Remote reset as an alternative to the mechanical reset options, an electrical remote reset can be used by applying 24 VDC to terminals A3 and A4
Touch safe terminal protects against accidental touching of live circuits
