3UB81334HW2 Application
For motor protection applications3UB81334HW2 Item Features
- 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
