Reading example for tripping
characteristic of type B

Behavior table on page 95, line B)
aThermal tripping characteristic:
conventional non-tripping current I1
= selected non-tripping current.
The MCB maintains 1.13 times
the rated current for at least
60 minutes.
Convetional tripping current I2
= selected tripping current
The MCB switches off within
60 minutes when 1.45 times
the rated current is reached.
bElectromagnetic
tripping characteristic AC:
The MCB maintains current rushes
exceeding 3 times the rated current
for more than 0.1 sec. (in this example
up to ca. 4 sec.).
The MCB switches off within less than
0.1 sec. when 5 times the rated current
is reached..

UC = Universal Current = AC/DC
S 280 UC MCBs can be used in the one-pole version as 220 V ...—, and in the
2-pole or 4-pole version with series connection of two poles up to 440 V ...—, .
S 280 UC differs from the standard S 280 type as it is fitted with permanent
magnets, which assists in the forced extinguishing of the arc.
If voltages to earth exceeding 220 V DC may occur, 2-pole S 280 UC is
to be used for one-pole disconnection, and four-pole 280 UC for all-pole
disconnection.
For DC incoming supply from above
S 280 UC-… MCBs have, in the area of arc chutes, permanent magnets, it
is therefore necessary to take into account the polarity during the installation
process.
Doing so ensures that in the case of a short circuit the magnetic field of the
permanent magnets corresponds with the electromagnetic field of the short-
circuit current, therefore safely leading the short circuit into the arc chute.
Incorrect polarities may cause damage to the MCB. This is why - in the case of
top-fed devices – terminal 1 must be connected to (-) and terminal to 3 (+).

How supplementary devices can be mounted
Additional retrofit devices
The following accessories can be easily added to MCBs of the S 280 UC series:
Auxiliary contact S2-H.. (X)
The auxiliary switch is fitted with 2 or 3 potential-free contacts and indicates clearly the position of the main contacts, i.e.
not only when the device trips due to overload, but also if switched off manually. Coupled to the contact mechanism, it is
trip-free.
The auxiliary switch comes either with screw-fixing or as plug-in device (switches with 3 potential-free contacts only
screw-type make).
Minimum switching capacity: 5 VA at 12 V
Minimum switching capacity: 0,1 VA at 12 V (H … kL, low power)
Connection capacity: 2 x 1.5 mm2
Pick-up torque: 0.8 Nm
Signal contact S2-S
Trips in the case of overload, earth leakage or short circuit, not, however, if switched off manually (has-tripped signal). The
signal (red acknowledgment button) can be cancelled without switching the MCB on again. Push the test button to check
on the control circuit and not interrupt the main circuit.
Undervoltage release UA (can be retrofitted to the left or the right)
For distance tripping of the MCB (switch OFF). An exciting coil makes it impossible to switch on the device unless a
voltage is applied. Where the supply voltage is interrupted or switched off, the undervoltage release makes the MCB trip
(suitable for emergency stop circuit).
Shunt trip AL . . . (can be retrofitted to the left)
For distance tripping of the MCB (switch OFF). The shunt trip has a relay coil with an integrated contact which
disconnects the coil and the coil voltage if the MCB trips, this prevents the continued flow of current in the case of
sustained coil voltage.
Separate supplementary devices
Neutral disconnector Nt
This component is fitted, if necessary, to the right of the MCB onto the mounting rail. It is used, e.g. to disconnect the
neutral prior to measurements. The design of the switching lever ensures that the neutral is lead-making contact when
the MCB is switched on.

The variety of functions makes the combined signal contact/auxiliary contact S2-S/H an excellent choice.
Additional retrofit devices
Signal contact/auxiliary contact S2-S/H
The signal contact and the auxiliary contact both have a potential-free changeover contact.
The contacts have a trip-free mechanism.
Minimum switching capacity 0.1 VA at 24 V.
Application examples
●If the MCB is switched off, e.g. due to an insulation test (deliberate interference), only the auxiliary contact trips,
but not the signal contact.
●The signal contact switch can be switched to test the control circuit (OFF by test button T
and ON with the operating lever), without disconnecting the main circuit.
●The signal contact switch can be reset, in order to e.g. acknowledge an acoustic signal switched via the device,
without causing the MCB to trip.
