Technical Information
NOARK B1N series Miniature Circuit Breakers are designed for branch circuit protection in accordance with UL 489 standards. These MCBs provide overcurrent and short circuit protection for electrical installations in residential, commercial, and industrial applications.
Trip Curve Characteristics:
- B-curve: Trips between 3-5 times rated current for magnetic tripping. Ideal for resistive loads with low inrush currents.
- C-curve: Trips between 5-10 times rated current for magnetic tripping. Suitable for general purpose and mixed resistive/inductive loads.
- D-curve: Trips between 10-20 times rated current for magnetic tripping. Designed for highly inductive loads with high inrush currents.
All B1N series breakers feature 35mm DIN rail mounting for easy installation and are available with either box lug or ring tongue connections to suit various application requirements.
