Pro M Miniature circuit breakers
General information
General information
Miniature circuit breakers (MCBs) are used
throughout the world in all types of electrical
installations. ABB MCBs are recognized for
use by Underwriters Laboratories Standard
UL1077 for supplementary circuit protectors in
www.DataSheets4yUs.tceomms rated 240VAC, 480VAC and 600VAC.
Devices are certified per CSA C22.2.
MCBs are approved per IEC-898 and VDE
0641, and certified under IEC-947 and VDE
0660 standards for use in systems rated
415VAC or 690VAC (S500 series).
MCBs can be applied to 16 2/3Hz – 400Hz
and DC power systems.
Special direct current version MCBs include a
permanent magnet for DC fault current
interruption. These "UC" versions are rated
250/500VDC under UL1077/CSA 22.2 No. 235.
Continuous current ratings are as low as 0.2
amperes and up to 125 amperes maximum.
MCBs are of compact size and can be quickly
mounted on standard 35mm DIN rail or can be
front mounted by use of a front mounting kit.
MCBs include line and load side terminals for
conductors from 18 through 4AWG (0.75 –
25mm2) for 40 amperes; up to 2AWG for 50
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 field
mounted to all above listed ABB MCBs.
Auxiliary contacts are also available for the
S500 series MCB.
Applications
MCBs can be used for equipment protection,
in commercial appliances, protection of
control circuits against overcurrent faults,
computer equipment and other computer
peripheral devices.
UL 1077
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
E76126.
ABB Control Inc.
CSA C22.2
MCBs and accessories are
certified under CSA C22.2
No. 235 per File LR98793.
Tripping
characteristics
Time-current curves
ABB miniature circuit
breakers are available
with different trip
characteristics, allowing
for maximum system
protection.
B Characteristic
Available with the S260
series has rated currents
of 6 through 63 amperes
in 10 steps. The "B" time-
current curve is designed primarily
for use in cable protection applications.
Instantaneous tripping occurs between
approximately 3 to 5 times rated current in 50/
60Hz systems. This quick trip curve
maximizes protection 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, 100 and 125
amperes. The "C" time-current curve is
designed for medium magnetic start-up
currents. Instantaneous tripping occurs
between 5 and 10 times rated current in 50/60
Hz systems. The "C" characteristic is also
available in other S2 Series MCBs.
D Characteristic
The new magnetic trip action has an
instantaneous trip point of approximately 15
times the breaker rating. 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 characteristic considers
high magnetic start-up currents from motors,
transformers and other equipment.
Instantaneous tripping occurs between 8 and
12 times rated current in 50/60Hz systems.
The "K" characteristic is available up through
63 amperes.
The "K" curve offers the best protection for the
broadest range of electrical systems. The
higher magnetic trip settings maximizes
protection while allowing for higher in-rush
currents during system start-up.
Z Characteristic
Also available up through 63 amperes, the "Z"
characteristic offers instantaneous tripping
between 2 and 3 times rated current in 50/
60Hz systems. This trip characteristic is
available in the S280 series with both the
480VAC and 250/500VDC ratings.
Many applications require a very low short
circuit trip settings in order to protect
semiconductor or other sensitive devices and
the "Z" trip characteristic may provide
maximum protection and service in these
applications.
