Factory-Installed Accessories for Thermal-Magnetic LA and Q-Frame Circuit Breakers

Accessory	Description		Rated Voltage	Coil Burden	Suffix
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	-1042
			120 Vac	24 VA	-1021
			208 Vac	107 VA	-1021
			240 Vac	154 VA	-1021
			277 Vac	14 VA	-1037
			480 Vac	45 VA	-1037
			24 Vdc	36 VA	-1027
			48 Vdc	36 VA	-1028
			125 Vdc	44 VA	-1029
			250 Vdc	15 VA	-1030
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		—	—	-G
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 -1121 -1124 -1127 -1128
Auxiliary Switches	Monitors circuit breaker contact status and provides a remote signal indicating the circuit breaker contacts are OPEN or CLOSED. Application Max. Load = 10 A @ 125–250 Vac, ¼ hp @ 125–250 Vac, 5 A @ 30 Vdc Leads: Yellow for “A’’, Blue for “B’’, Striped for common 18 AWG Cu	1A/1B	See load info. in App. text at left	See load info. in App. text at left	-1212
