The Bosch 500 Series NIT5663UC is a 36″ frameless induction cooktop designed for modern kitchens that need responsive heat, a wide cooking surface, and a clean built-in look. Induction transfers energy directly into compatible cookware, helping pans heat quickly while the surrounding glass remains easier to manage than a traditional radiant element. Five induction cooking zones give the cooktop room for everyday meals and larger cookware. The centre triple-ring element automatically adjusts from 9″ to 13″ cookware, while SpeedBoost adds extra power when you want to bring water to a boil quickly. Touch controls keep the surface streamlined, and the Favorite button can recall two commonly used settings through Home Connect. Residual heat indicators and automatic safety shut-off add useful peace of mind for a busy kitchen.
