Product details

Ratings that matter for the panel builder

At DC per the same standard it's rated 15 kA. Temperature derating is published: full 2 A up to 45 °C, then 1.95 A at 50 °C, 1.9 A at 55 °C. The breaker is also halogen-free and silicon-free — relevant for sensitive environments like semiconductor fab or food processing where outgassing contaminants matter. The sealable feature (padlockable toggle) lets you lock out a circuit for LOTO compliance without an external lockout tagout device. Touch protection is integrated per the product feature listing.
