Miniature Circuit Breakers

Miniature Circuit Breakers (MCBs) are essential electrical components
designed to safeguard circuits and connected devices from
overcurrents.

Using thermal, magnetic, or both mechanisms, MCBs automatically
interrupt electric currents to prevent damage during abnormal
conditions like short circuits and overloads. They are compact,
making them suitable for limited-space applications. These products
are rated by breaking capacity, indicating the maximum fault current
they can interrupt safely without damage. MCBs come in a range
of current ratings to accommodate different electrical loads. This
product is manufactured in compliance with international standards
such as IEC 60898 and IEC 60947.

Air Circuit Breakers

Air Circuit Breakers (ACBs) are designed to automatically disconnect
circuits during overcurrents or short circuits, preventing damage
to the system and connected equipment. ACBs employ diverse
tripping mechanisms – thermal, magnetic, and electronic to provide
a versatile response to various fault conditions. One of their notable
features is the ability to adjust protection settings, including current
ratings and tripping curves, allowing for customisation based on
specific load and application requirements.

With high breaking capacities, ACBs can safely interrupt substantial
fault currents. Their modular design facilitates easy installation and
maintenance, providing adaptability to evolving system needs.

Moulded Case Circuit Breakers

Sace ISOMAX and Tmax, ABB’s flagship Moulded Case Circuit Breakers
(MCCB) series, are integral components in electrical distribution
systems, delivering robust overcurrent protection.
SACE ISOMAX stands out for its compact design, allowing for versatile
installations in constrained spaces. Notable for adjustable settings, it
offers a tailored approach to thermal and magnetic trip elements.

The Tmax series is recognised for its high-performance attributes
and modular construction, ensuring adaptability to evolving electrical
system needs. Tmax MCCBs incorporate energy management
features, providing insights into power consumption for enhanced
efficiency. Both series adhere to international standards, and offer
remote control and monitoring options.
