Miniature Circuit Breakers S260, S270, S280, S290 Description The S2 Series of miniature circuit breakers offer a compact solution to protection requirements. The breakers are recognized under standard UL 077 as supplemental protective devices. The S2 devices are current limiting, DIN rail mounted and can offer a good equivalent to fused systems. The S2 is available with application-specifi c trip characteristics to provide maximum circuit protection. The breakers offer thermal-magnetic trip protection according to B, C, D, K and Z characteristics. For the worldwide market, the breakers carry UL, CSA, IEC, CE and many other agency approvals and certifi cations.

General information S260, S270, S280, S290 General information Miniature circuit breakers (MCBs) are used throughout the world in all types of electrical in stal la tions. ABB MCBs are recognized for use by Un der writ ers Lab o ra to ries Stan dard UL077 for sup ple men ta ry circuit pro tec tors in systems rated 240V, 480V and 600V. Devices are certifi ed per CSA C22.2. MCBs are approved per IEC-898 and VDE 064, and certifi ed under IEC-947 and VDE 0660 standards for use in sys tems rated 4V or 690V (S00 series). MCBs can be applied to 6 2/3Hz 400Hz and power systems. Special direct current version MCBs include a per ma nent magnet for fault current in ter rup tion. These "UC" versions are rated 20/00V under UL077/CSA 22.2 No. 23. Continuous current s are as low as 0.2 amperes and up to 2 amperes maximum. MCBs are of compact size and can be quickly mounted on standard 3mm DIN rail or can be front mounted by use of a front mounting kit. MCBs include line and load side terminals for conductors from 8 through 4AWG (0.7 2mm 2 ) for 40 amperes; up to 2AWG for 0 and 63 amperes. MCBs can also be connected via busbar conductors which can be either upper or lower mounted for top feed or bottom feed. Dual function terminals allow busbars to be connected with main incoming line conductors without separate lugs. Accessories Auxiliary devices can be added to S260, S270 and S280 series MCBs: Shunt trips Auxiliary contacts Trip contacts Aux/trip contacts Undervoltage release Accessory device modules can be fi eld mounted to all above listed ABB MCBs. Auxiliary contacts are also available for the S00 series MCB. Applications MCBs can be used for equipment protection, in com mer cial ap pli anc es, protection of control circuits against overcurrent faults, computer equipment and other com put er peripheral devices. UL 077 MCBs are recognized as supplementary protectors and are intended for use as overcurrent protection within an appliance or other electrical equipment where branch circuit overcurrent protection is already provided or not required. MCBs and accessories are recognized under UL File E7626. CSA C22.2 MCBs and accessories are certifi ed under CSA C22.2 No. 23 per File LR98793. Tripping characteristics Time-current curves ABB miniature circuit breakers are available with different trip char ac ter is tics, allowing for maximum system protection. B Char ac ter is tic Available with the S260 series has rat ed currents of 6 through 63 amperes in 0 steps. The "B" time-current curve is de signed primarily for use in cable protection applications. Instantaneous tripping occurs between ap prox i mate ly 3 to times rated current in 0/60Hz sys tems. This quick trip curve maximizes pro tec tion of control circuits under low short circuit fault levels that could damage control wiring. C Characteristic Available in the S260 series with rated currents up though 63 amperes and the S290 series with rated currents of 80, 00 and 2 amperes. The "C" time-current curve is de signed for medium magnetic start-up currents. Instantaneous tripping occurs between and 0 times rated current in 0/60 Hz systems. The "C" characteristic is also available in other S2 Series MCBs. D Characteristic The new magnetic trip action has an instantaneous trip between 0 and 20 times the breaker. Thus, the S260-D can be a good protective solution for applications involving high in-rush transformers, motors and other high inductive systems. The 260-D is also suitable for any application where a high instantaneous trip point is desired. K Characteristic The "K" time-current char ac ter is tic considers high magnetic start-up currents from motors, trans form ers and other equipment. Instantaneous trip ping occurs between 8 and 2 times rat ed current in 0/60Hz systems. The "K" char ac ter is tic is available up through 63 amperes. The "K" curve offers the best pro tec tion for the broad est range of electrical systems. The higher magnetic trip settings max i miz es protection while allowing for higher in-rush currents during system startup. Z Characteristic Also available up through 63 amperes, the "Z" char ac ter is tic offers instantaneous tripping between 2 and 3 times rated current in 0/60Hz systems. This trip characteristic is available in the S280 series with both the 480V and 20/00V s. Many applications require a very low short circuit trip settings in to protect semiconductor or other sensitive devices and the "Z" trip characteristic may provide maximum pro tec tion and service in these applications..2 Low Voltage Products & s 000 - /03 ABB Inc. 888-38-22 www.abb-control.com

S2-H2 4 2 N.O./ N.C. S2-H2 4 2 N.O./ N.C. (low voltage) S2-H2KL 60 A.4 The S2-H auxiliary switch can be fi eld mounted to any S260, S270 or S280 series breaker. The auxiliary contacts will signal whether the breaker is in the ON or OFF position. The contacts are rated 6A/240 V and.a/0 V. Minimum ope voltage is 2 V/V. Wire size: 8 AWG to 6 AWG. Bell alarm For fi eld mounting, left side S2-S 48 A.4 The S2-S bell alarm includes a set of contacts that will only signal when the breaker has tripped. Typically the contacts would be connected to an alarm or bell to signal the operator that an overcurrent trip has occured. The bell alarm also includes a test button for testing the alarm contacts without opening the breaker. The contact is rated 6A/240 V and.a/0 V. Minimum ope voltage is 2 V/V. S2-A Bell alarm with auxiliary contact For fi eld mounting, left side S2-S/H 8 A.4 The S2-S/H bell alarm with auxiliary contact device combines one set of bell alarm contacts with one set of auxiliary contacts (N.O.). S2-BM Shunt trip For fi eld mounting, left side 2-60 V (2-60V) S2-A 0-4 V (0-20 V) S2-A2 38 A.2 For remote tripping of breaker, a shunt trip device can be added to the MCB. The solenoid device opens the breaker after control voltage is applied. Shunt trips are available depending on control system voltage (2-4 V/V). Undervoltage release For fi eld mounting, left or right side 2 V S2-BM 24 V/V S2-BM2 48 V/V S2-BM3 0 V/V S2-BM4 220 V/V S2-BM 380 V S2-BM6 26 A.2 When control voltage drops below approximately 0% of rated voltage, the S2-BM opens the breaker. The breaker can not be operated unless proper control voltage is fi rst applied to the UVR coil. Similar in size and mounting to the shunt trip accessory; can be left or right side mounted. S2-S Hand operated neutral disconnect For fi eld mounting, right side, 40A max. S2-NT 27 A.4 Wire range: -8 AWG. Must be turned off manually. Not UL Listed. S2-NT is only /2 pole width. S2-S/H Factory mounting All accessories can be easily mounted in the fi eld. For factory mounting of any accessory devices, add $30 list to total price per breaker. To create complete catalog number, take suffi x of accessory device following S2- and add suffi x to end of breaker part number. Multiple suffi xes must be added in alphabetical.
