Average Time Current Curves

• 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.
