Additional Information
Overload Protection: Equipped with thermal overload protection based on a bimetal strip that trips the circuit breaker when the temperature limit is exceeded. The adjustable current setting ranges from 0.7 to 1 times the trip unit rating (16A to 250A), allowing for tailored protection.
Short-Circuit Protection: Features magnetic protection that triggers instantaneous tripping for excessive current. The fixed pick-up settings cater to ratings from 16A to 160A, with adjustable options available for higher ratings.
