Circuit Breaker Accessories Factory-Installed Accessories Electrical accessories are available on all molded case circuit breakers except FY and QOM1 circuit breakers. ● Alarm switch is the only accessory available for the 1-pole FA circuit breaker. ● Combination accessories may be ordered by description, i.e., 1021 and 1212. ● All AC electrical accessories shown below are rated for 50/60 Hz. ● Add 20% to accessory price for each field-installable accessory that is factory-installed. ● See page 3-25 for field-installable accessories. See Digest page 7-35 for PowerPact® circuit breaker accessories. Table 3.63: Factory-Installed Accessories for Thermal-Magnetic Circuit Breakers Accessory Description Rated Voltage Coil Burden a Suffix $ Price Adder Shunt Trip Trips the circuit breaker from a remote location by means of a trip coil energized from a separate circuit. A 120 V shunt trip will operate at 55% or more of rated voltage. All other shunt trips will operate at 75% or more of rated voltage. Application ▪ For use with momentary or maintained push button. ▪ Sure Trip Capacitor Unit requires 48 Vdc shunt trip. ▪ Leads: (2) Black.18 AWG Cu. 24 Vac 21 VA -1042b 503.00 120 Vac 24 VA -1021c 503.00 208 Vac 107 VA -1021 503.00 240 Vac 154 VA -1021 503.00 277 Vac 14 VA -1037b 503.00 480 Vac 45 VA -1037b 503.00 24 Vdc 36 VA -1027 503.00 48 Vdc 36 VA -1028 503.00 125 Vdc 44 VA -1029 503.00 250 Vdc 15 VA -1030d 503.00 Ground- fault Shunt Trip Trips the circuit breaker electrically using the signal from a Micrologic® Ground-Fault Module. Application ▪ For use only with obsolete GP Ground-Censor® system or add on ground-fault module. ▪ Leads: (2) Orange 18 AWG Cu. — — -Gd 503.00 Undervoltage Trip (UVR) Trips the circuit breaker electrically when a control circuit falls below 35 to 70% of nominal (not field adjustable). Picks up at 35–85% of nominal voltage. Application ▪ UVR must be energized in order to close the circuit breaker. ▪ Leads: (2) Brown 18 AWG Cu leads. 24 Vac 120 Vac 240 Vac 24 Vdc 48 Vdc 5 VA 8 VA 8 VA 2 VA 3 VA -1143 d -1121 -1124 -1127 -1128 503.00 503.00 503.00 503.00 503.00 Time Delay Unit Provides adjustable time delay for UVR of 0.1 to 0.6 second before circuit breaker trips.
