Complies with electronic industry environmental standards for
lead reduction.
Product is compatible with lead-free solders and higher
temperature profiles.
Time delay feature withstands high in-rush currents and prevents
nuisance openings.
Package is visually distinct from fast-acting version for easy identification.
Top side marking allows visual verification of amperage rating.
