Description
The S2 Series of miniature circuit breakers
offer a compact solution to protection
requirements. The breakers are recognized
under standard UL 1077 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

Direct current applications
The S280UC differs from standard miniature circuit breakers in that the UC versions include a permanent
magnet which aids in the extinguishing of the arc during medium and high level faults. It is necessary to
observe the correct polarity and current direction when connecting the UC breakers. Two examples of correct
connection are shown below.
Termination points are marked on all UC type MCBs, points one (1) and four (4) are negative and points two
(2) and three (3) are positive. Four pole breakers are also available for voltage reversal applications.

The S2-H11 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 VAC and 1.5A/110 VDC. Minimum operating voltage is 12 VAC/VDC.
Wire size: 18 AWG to 16 AWG.
Bell alarm
For fi eld mounting, left side S2-S 48 A 1 1.4
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 VAC and 1.5A/110 VDC. Minimum operating voltage is 12 VAC/VDC.
Bell alarm with auxiliary contact
For fi eld mounting, left side S2-S/H 58 A 1 1.4
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.).

110 VAC/VDC S2-BM4
220 VAC/VDC S2-BM5
380 VAC S2-BM6
When control voltage drops below approximately 50% 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.
Hand operated neutral disconnect
For fi eld mounting, right side, 40A max. S2-NT 27 A 1 1.4
Wire range: 14-8 AWG. Must be turned off manually. Not UL Listed. S2-NT is only 1/2 pole width.
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 order.
Example: S272-K20A1 $ 264 (2 pole, 20A breaker with type A1 shunt trip) S272-K20 @ $96 + A1
@ $138 + factory mounting @ $30 = $264
S272-K20A2H11 $ 300 (2 pole, 20A breaker with type A2 shunt trip and H11 aux. contacts) S272-
K20 @ $96 + A2 @ $138 + H11 @ $36 + factory mounting @ $30 = $300
Auxiliary contacts and shunt trips may be mounted in combination.

Mounting
Universal mounting position using snap-on mounting
to standard 35x7.5mm 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 2.12).
Connection
Terminals are suitable for solid or fl exible conductors
from 18 to 4 AWG (0.75 to 25mm2) with no busbar
connected. When max i mum busbar size of 36 mm2
is used, maximum cable is 6 AWG (16 mm2).
Maximum tightening torque of 17.5 in-lb (2 Nm)
for line/load terminals and 4.5 in-lb (0.5Nm) 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.

Many older styles of ABB miniature circuit breakers have been replaced by new and improved versions. Many of these newer styles can be directly interchanged, both
electrically and physically, with the older version. There are also many international styles of ABB circuit breakers which are not normal stock items and may be inter-
changed with stocked ABB versions.
Note: MCB types S260/270 and S280 can be raised to the same height as older style S210 series MCBs through the use of a height adjuster (SZ-ES68/83; $ 30 list per
20). The height adjustor snaps onto the DIN rail and raises the height of com po nents 68mm to match that of the S210 series (83mm).

F370, F670 series
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.
2 Pole 4 Pole
The F370 and F670 series are UL1053
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.
