About ABB SACE TMAX 250 AMP MCCB

MCCB stands forMolded Case Circuit Breaker. It is another type of electrical protection device which is used when load current exceeds the limit of a miniature circuit breaker. The MCCB provides protection against overload, short circuit faults and is also used for switching the circuits.

Advanced Protection for Modern Electrical Systems

The ABB SACE TMAX 250 AMP MCCB offers steadfast security for demanding industrial and commercial facilities. Designed to handle overload and short circuit protection, it operates efficiently at temperatures from -25C to +70C. Its thermal and magnetic trip settings can be adjusted to suit specific requirements, providing adaptable, reliable safeguarding of electrical infrastructure.

Built to Meet Stringent International Standards

Ensuring global compatibility, this MCCB complies with IEC 60947-2 and delivers a breaking capacity of 36 kA at 415V AC. Its insulation voltage of 800V AC and high rated impulse withstand voltage of 8 kV guarantee optimal performance in challenging environments, supporting a wide range of applications and installation scenarios.

Flexible Installation and Accessory Integration

With a choice of fixed or plug-in mounting and compatibility with auxiliary contacts, shunt trips, and undervoltage release devices, the ABB SACE TMAX 250 AMP MCCB is engineered for versatile integration. Its screw type terminals and panel mounting make installation straightforward for distributors, exporters, and suppliers across India.

FAQ's of ABB SACE TMAX 250 AMP MCCB:

Q: How does the ABB SACE TMAX 250 AMP MCCB protect against overload and short circuits?

A: The MCCB uses a thermal-magnetic trip unit, which detects thermal overloads and instantaneous short circuits. When excessive current flows, the thermal element triggers protection for overload situations, while the magnetic element provides rapid response to short circuit events.

Q: What is the process for adjusting the thermal and magnetic trip settings on this MCCB?

A: Adjustment is done using the accessible controls on the MCCB. The thermal trip settings can be tuned from 0.7 to 1 times the rated current (In), whereas the magnetic trip settings are adjustable between 7 to 10 times the rated current. This allows precise calibration for different application demands.

Q: When should auxiliary contacts, shunt trip, or undervoltage release accessories be used with this MCCB?

A: These accessories are employed to enhance system control and safety. Auxiliary contacts provide panel status signals, shunt trip allows remote circuit interruption, and undervoltage release ensures disconnection during voltage drops. They are used based on operational requirements and protection schemes.

Q: Where is the ABB SACE TMAX 250 AMP MCCB typically installed?

A: This MCCB is designed for panel mounting in industrial and commercial electrical distribution systems. Its fixed or plug-in installation options offer flexibility for various environments across India and beyond.

Q: What benefits does the IP20 degree of protection offer for this MCCB?

A: The IP20 protection rating secures the internal components against accidental contact with fingers or similar objects, enhancing operator safety and reducing the risk of electrical hazards during routine operation or maintenance.

Q: How does the product's electrical life and mechanical life impact its usage?

A: With an electrical life of up to 10,000 operations and mechanical life up to 20,000 operations, the MCCB assures sustained reliability and performance over its service life, supporting long-term use in critical installations without frequent replacement.
