The Z curve provides a narrow magnetic trip band (typically 2 to 3 times In), making it suitable for protecting semiconductor circuits, control transformers, and other sensitive electronic loads where standard B or C curves would allow damaging overcurrent to pass before tripping.
Panel integration
Snap-on mounting to DIN rail EN 60715. The 2-pole width occupies 36 mm (2 module spaces) on the rail. Rated for use in enclosure ambient temperatures up to 40 °C without derating; above that, follow the manufacturer's thermal derating curve published in the product datasheet.
