ABB 1SDA068353R1 Circuit Breaker

Description

• The ABB 1SDA068353R1 is a circuit breaker belonging to the TMAX XT4H 160 series, designed for electrical distribution and protection purposes. This specific model features a fixed four-pole configuration with front terminals, allowing for convenient installation and connection. The circuit breaker is equipped with a thermomagnetic release mechanism known as TMA (Thermal-Magnetic Adjustable), which provides combined thermal and magnetic protection against overcurrent and short-circuit faults.

• The "TMA R 80 I3=400...800 A" specification indicates that the thermomagnetic release of the circuit breaker is designed to trip the breaker within the range of 400 A to 800 A, providing protection against overcurrent conditions. The adjustable thermal delay allows customization of the response time based on the specific requirements of the electrical system.

• Thermomagnetic circuit breakers are commonly utilized in a wide range of applications to safeguard electrical systems and equipment from damage due to excessive current conditions. The incorporation of both thermal and magnetic protection elements ensures effective response to prolonged overcurrent situations as well as high short-circuit currents.
