Average Time Current Curves
• For RoHS compliant and Lead-Free designs use 468 series
• 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.
