This chapter contains important safety information. Be sure to carefully read these safety notices, instruction in this manual, and other documents accompanying the Air Circuit Breaker (hereinafter referred to as the ACB) to familiarize yourself with safe and correct procedures or practices before installing, operating, or servicing the ACB.

Terasaki Electric's AR325S is a circuit breaker 3/4pole 2500a 690v. in the overcurrent protection, circuit breakers category. Check part details, parametric & specs and download pdf datasheet from datasheets.com, a global distributor of electronics components.

The TemPower 2 ACB can be equipped with a range of industrial communications options, allowing it to be easily integrated into an Energy Management System (EMS) or Building Management System (BMS).

The neutral pole is positioned to the right as standard when viewed from the front of the ACB. However, the neutral pole can be customized so that it is positioned to the left.

Minimal derating at high ambient temperatures reduces the need to ‘oversize’ the ACB rating in arduous environments, saving switchgear costs. Uniform panel cut out size which supports repetitive production of panel doors, saving labour cost and resulting in a clean, consistent look.

Air Circuit Breakers PATENTED! Double contacts, double opening coils, double closing coils are unique to the TemPower 2 ACB 2023

Air Circuit Breakers (ACBs) are primary protective devices in large switchboards, disconnecting power in case of short circuits or overloads. They are ideal for large buildings, manufacturing sites and infrastructure projects needing low voltage power.
