When evaluating an MCCB (Molded Case Circuit Breaker) for industrial or commercial applications, the focus is on reliability and performance. This particular MCCB is designed to meet rigorous standards, ensuring dependable operation in various environments.
With a rated current of 40 A, this MCCB offers ample capacity for medium-duty electrical systems. Its rated insulation voltage of 1000 V and impulse withstand voltage of 8 kV ensure high-level protection against electrical surges and spikes, crucial for safeguarding sensitive equipment.
The device operates at a maximum rated voltage of 690 VAC, making it versatile for different power networks. It supports both 50 Hz and 60 Hz frequencies, offering flexibility across diverse regions and setups.
Equipped with an Ekip Dip LSI trip unit, this MCCB provides precise control over its tripping characteristics—essential for maintaining system integrity during fault conditions. The release type is EL (electronic), which enhances accuracy in detecting overloads or short circuits.
A breaking capacity of 15 kA ensures that the MCCB can handle significant fault currents without compromising safety or functionality. This feature is vital in preventing damage to the circuit and connected devices during unexpected faults.
Designed with three poles, the breaker accommodates balanced load distribution across phases. The front connection type allows straightforward installation and maintenance access. Additionally, the bolt terminal type ensures secure connections that are resistant to loosening under vibration or thermal cycling.
With a width of just 105 mm, this compact unit fits neatly into standard panels without consuming excessive space—a critical factor in modern installations where panel real estate is often limited.
Compliance with IEC60947-2 standards underscores its adherence to international safety and performance benchmarks—providing peace of mind regarding operational reliability and compliance requirements.
Despite its robust construction weighing in at 2.5 kg, this MCCB maintains efficiency with a low power loss of only 0.6 W—minimizing energy wastage while contributing to overall system efficiency.
The degree of protection rating at IP20 makes it suitable for indoor use where moderate protection from solid objects like fingers or tools is sufficient but not exposed to water ingress risks.
This product supports main circuit connecting capacities ranging from 85-200 sq-mm cables—a testament to its adaptability across different installation scales—from small industrial setups to larger commercial infrastructures.
For those integrating this breaker into systems using XT4H components, compatibility ensures seamless integration without requiring extensive modifications or additional accessories—streamlining both new installations and upgrades alike.
