TEMPOWER 2 Air Circuit Breaker Brochure

Product catalog summary

Introduction
Terasaki's TemPower 2 ACB, known as the Double Breaker, prioritizes safety and protection. It is one of the smallest ACBs globally, offering high specifications and reliability.

Protection Relay Guide
The TemPower 2 Protection Relay Range features RMS Sensing and various protection functions, including overload protection, reverse power trip, N-phase protection, adjustable undervoltage trip, advanced LCD display (AGR-22), remote communications, and contact temperature monitoring.

Key Features

Breaking Contacts: The world's first Double Break ACB with two breaking contacts per phase, ensuring high short-time withstand rating.
Packing Density: Offers increased switchboard packing density with compact dimensions.
Reliability: Enhanced service life with superior electrical and mechanical endurance ratings.
Double Quick Opening: Clears short-circuit faults in less than 30ms, twice as fast as most ACBs.
Protection Characteristics: Complies with IEC 60 947-2, IEC 60 255-3, and Lloyds Register of Shipping standards, with LSI protection.
Double Insulation Properties: Ensures operator controls and accessory locations are double insulated.
Double Opening and Closing Coils: Allows for redundant control systems.
Double Neutrals: The AH-60DN model supports 10,000A of neutral current, addressing harmonic currents.
Reduce Time to Repair: Modular construction allows pole replacement in about 15 minutes.
Control and Monitoring Options: Supports Modbus, Profibus, Lontalk, and Devicenet protocols for circuit breaker control and monitoring.

Now you can extend control system redundancy to an ACB. Double coils allow designers to implement back-up tripping and closing systems. > TemPower 2 is the worlds first Double Break ACB, having two breaking contacts per phase. The unique pole structure means that the short-time withstand rating (Icw) is equal to the service short-circuit breaking capacity (Ics) for all models. > You can increase switchboard packing density usingthe smallest one-second rated ACB on the market. The fixed version is 290mm deep, the drawout version is 345mm deep. > How do you make a system harmonic proof in the face...
