Introduction
ABB is once again demonstrating its
commitment to new product development
and its superiority in product performance.
Never before has the industry seen such high
performance, versatility and standardization
in a range of molded case circuit breakers.
The ABB Tmax has been developed to
complement the performance-proven Isomax
line of circuit breakers. This new breaker,
with a range up to 600A, has several very big
features that go along with its very small size:
• Double insulation – this construction
characteristic allows for the UL Listed
fi eld installation of internal accessories
without exposure to the power poles.
• Positive operation – all molded case
breakers from ABB ensure that the toggle
indicates the precise position of the
moving contacts. This guarantees safe
and reliable signaling by the device.
• Installation – Tmax Series can be installed
in panels and switchboards in either the
horizontal or vertical planes while being
fed from either end without any derating
of their performance characteristics.
• Two ranges of accessories – in the pursuit
of standardization, all Tmax internal and
external accessories can be utilized
across the entire range from 15A to 600A.
• Interrupt ratings at 480VAC up to
150kAIC.
• Compact size
• UL Listed and IEC rated for global
application and acceptance.
The ABB Tmax has the performance and
accessories to satisfy all industry requirements
in the 600VAC to 600VDC ranges. A single pole
molded case version is available for the fi rst
time.
