Product Positioning

The 5SJ4318-7HG42 is a 3-pole 15A model from the SENTRON 5SJ4 series. It adopts the C-operation curve and is suitable for 480Y/277V AC high-voltage systems. Compared with the 240V model, it can be used in US standard distribution circuits with higher voltage levels.

Core Product Advantages and Features

480Y/277V high voltage model

With a rated voltage of 480V/277V AC, it is suitable for power distribution systems with higher voltage levels than the general 240V models.

C Action Curve

The instantaneous trip current is approximately 5 to 10 times the rated current, making it suitable for general mixed resistive and inductive load circuits.

3-pole 15A specification

With a three-pole linkage design and a rated current of 15A, it is used for three-phase power circuit protection.

UL489 certification

Compliant with North American UL489 standards, suitable for high-voltage switchboards requiring UL-certified components.
