| 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 |
