1 Miniature Circuit Breakers S260, S270, S280, S290 S260 S290 MCBs 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. Features Current limiting Fast breaking time (2. 3. msec) Unique bus connection system Wide range of accessories Available with variable depth handle mechanism Optional Z curve for SCR protection CE certified and marked DIN rail or front panel mounting Finger safe terminals Multi-function terminals Suitable for reverse feed UL 077 and CSA /480VAC and 0V versions Low Voltage Products & s.

19 Technical data Mounting and operating instructions Mounting MCB Removing MCB Mounting Universal mounting position using snap-on mounting to standard 3x7.mm DIN rail. Miniature circuit breakers (MCBs) can also be mount ed to front of door using a panel cut-out with breaker handle pro trud ing through panel opening for external operation. Special front mount ing kit type ME is avail able (see page 2.2). Connection Terminals are suitable for solid or fl exible conductors from 8 to 4 AWG (0.7 to 2mm 2 ) with no busbar connected. When max i mum busbar size of 36 mm 2 is used, maximum cable is 6 AWG (6 mm 2 ). Maximum tightening torque of 7. in-lb (2 Nm) for line/load terminals and 4. in-lb (0.Nm) for ac ces so ry device terminals. Operation MCBs are switched on by moving the handle to the upper po si tion. Stamped onto the handle switch, a I is visible confi rming that the breaker is closed. The MCBs are trip-free, if the handle is being forced to the ON position, the breaker will still trip under fault conditions. The O marking indicates that the breaker is in the OFF position. The MCB is now open and the load is disconnected from line power. When a breaker has tripped, the MCB handle should fi rst be set to the full OFF position to make certain the trip mechanism has been reset. Once the fault has been determined and cleared the MCB can again be switched ON. Maintenance ABB miniature circuit breakers require no special maintenance; only normal electrical system maintenance pro ce dures are required.

Only the lower terminal is dual func tion. Terminals allow for con nec tion of cable 8-4 AWG. Conductors of different sizes may also be used in same terminal. Up to fi ve conductors, 6 AWG each, can be safely connected per terminal. Lower terminals can be bussed together with single phase or multi-phase busbars as shown. Upper ter mi nals can also be busbar con nect ed. Lower terminal can also be bussed with solid round con duc tor.

43 Residual current devices F370, F670 series 2 Pole 4 Pole Description RCDs provide ground fault equipment protection by monitoring the leakage of current to ground. The F370 and F670 series will trip when ground faults are detected in excess of the GF trip rating of the device. These devices provide GF pro tec tion only and are used in series with standard MCBs which provide overload and short circuit protection. The F370 and F670 series can be used as a main device providing GF protection for several MCB branch devices. The F370 and F670 series are UL03 recognized for use in 277/480VAC applications. The F372 is for use in single phase/two wire or two wire systems. The F374 is for use in three phase/four wire systems. The F370 and F670 series RCDs replace the F360 and F660 series with no change in form, fi t or function. The F370 and F670 have a profi le similar to the S2 MCBs and can be used with the MCB busbars.
