ABB 1SDA054178R1 Circuit Breaker TMAX T4N 250

Description

• The ABB 1SDA054178R1 is a circuit breaker belonging to the TMAX T4N 250 series, designed for electrical distribution and protection applications. This specific model features a fixed three-pole configuration with front terminals, allowing for convenient installation and connection.

• The circuit breaker is equipped with a thermomagnetic release mechanism known as TMA R 200. The "R 200" specification indicates the release's current rating, meaning that it is designed to operate within a range of 1000 to 2000 amperes. Thermomagnetic releases combine thermal and electromagnetic tripping mechanisms to provide reliable and adjustable protection against both overcurrent and short-circuit conditions.

• Circuit breakers with thermomagnetic releases are commonly used in a wide range of industrial and commercial settings to safeguard electrical systems and equipment from potentially damaging current fluctuations. The combination of thermal and electromagnetic tripping ensures that the circuit breaker can respond effectively to various types of fault conditions, offering enhanced versatility and protection.
