In the realm of industrial electrical protection and distribution, the TERASAKI brand stands as a benchmark for high-performance circuit breakers and switchgear. These devices are engineered for critical applications requiring robust short-circuit interruption capabilities, typically ranging from 25kA to 200kA at 415V AC, with rated currents from 16A up to 6300A in molded case (MCCB) and air circuit breaker (ACB) formats. TERASAKI products are known for their compact design, high breaking capacity, and advanced electronic trip units offering adjustable protection curves (L, S, I, G). They are available in 3-pole (3P) and 4-pole (4P) configurations, with rated insulation voltages up to 1000V, making them suitable for both low-voltage primary and secondary distribution. The range includes fixed and draw-out versions, with a wide array of accessories such as shunt trips, undervoltage releases, auxiliary contacts, and motor operators for remote control.
TERASAKI circuit breakers are predominantly installed in main distribution boards (MDBs), sub-distribution panels, and motor control centers (MCCs) across heavy industries. Key sectors include petrochemical plants, refineries, power generation facilities, data centers, and large commercial complexes. They are also widely used in marine and offshore applications due to their compliance with classification societies like Lloyd's and DNV. The robust construction ensures reliable operation in harsh environments, including high ambient temperatures and vibration-prone settings. For automation systems, TERASAKI breakers integrate seamlessly with PLC and SCADA systems via communication modules, enabling real-time monitoring and remote tripping.
Our catalog features the TERASAKI TemBreak series, including the TemBreak 2 (TB2) and TemBreak 3 (TB3) molded case circuit breakers, as well as the AR series air circuit breakers. Key article codes include the TB-160N, TB-250N, TB-400H, and TB-630S for MCCBs, and the AR-1600, AR-2000, and AR-3200 for ACBs. The code structure typically follows the pattern: [Series]-[Frame Size][Breaking Capacity Suffix], where 'N' denotes normal, 'H' high, and 'S' super high breaking capacity. For example, TB-400H indicates a TemBreak 2 series, 400A frame, high breaking capacity. We also stock the ProTect series for smaller installations and the TMAX series for advanced applications.
