Following are the part numbers and voltage ratings of undervoltage trip accessories for Powerpact B circuit breakers.
LV426801 (24 Vac and 24 Vdc)
LV426802 (48 Vac and 48 Vdc)
LV426803 (110-130 Vac and 125 Vdc)
LV426804 (220-240 Vac)
LV426805 (208-277 Vac)
LV426806 (380-415 Vac)
LV426807 (380-480 Vac)
LV426815 (250 Vdc)

Trips the circuit breaker when the control voltage drops below 35% of its rated voltage.
Between 35% and 70% of the rated voltage, opening is possible but not guaranteed.
Above 70% of the rated voltage, opening does not take place.
Continuous duty rated coil
Circuit breaker closing is possible only if the voltage exceeds 85% of the rated voltage. If an undervoltage condition exists, operation of the closing mechanism of the circuit breaker will not permit the main contacts to touch, even momentarily (this is commonly called “Kiss Free”).
