Features Benefits
b
Trip Classes - 5, 10, 20, or 30 Selectable by DIP-switches
b
Field changeable reduces time and inventory. Suitable for
light, normal and heavy starting conditions
b
Phase Loss Protection - Trips in less than 3 Seconds
b
Protects motor burn out and minimizes motor heating up
b
Phase Unbalance - Trips based on Trip Class selected
b
Minimizes temperature rise of the motor on a asymmetrical
three-phase-system
b
Ground Fault - Trips 60% of Motor Current
b
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
b
Trip Indicator - Visible
b
Save time, faster to identify overload Trip
b
Ambient Insensitive
b
Prevents nuisance tripping
b
No Heaters Required
b
Saves cost and eliminates time for installation of heaters
b
Self-Powered - No outside source required
b
Reduce cost for external power supply
b
FLA dial with wide Adjustment - 4:1 ratio
b
Provides wide range, reduces inventory
b
Self Protected in short circuit condition (when used with
proper fuses or motor starter protector)
b
Unlike bimetal overloads, this eliminates replacement of the
overload heaters after short circuit
b
Test Button - Tests Electronics
b
Tests the complete electronic functions including the trip
mechanism. Increases up time
b
Thermal Memory
b
Prevents re-starting motor when it is still hot
b
Conformally coated circuit board
b
Resists against environmental conditions
b
1 NO and 1NC Contacts Standard. B600, R300
b
Makes it easier for user to wire local contacts
b
Operating Temperature: -25 °C - 65 °C
b
Wide operating temperature range prevents nuisance tripping
with temperature changes
b
Repeat Accuracy <1%.
b
For more precise settings and reduced nuisance tripping
b
Removable Terminal Block
b
Terminal Block can be removed without removing wires.
Saves time for replacements
b
Automatic reset
b
Auto. Reset is 3 minutes after tripping, allowing motor to
cool down before re-start. If Manual Reset is selected,
overload can be reset immediately
b
Remote reset
b
As an alternative to the mechanical RESET options, an
electrical remote RESET can be used by applying 24 V DC
to terminals A3 and A4
b
DIN Rail Mounted
b
Reduces installation time
b
Touch - Safe Terminals
b
Protects against accidental touching of live circuits
b
UL listed CSA certified
b
Third party approval standard
