Overview

Rated at 40A with a K-characteristic tripping curve, it provides optimized protection for inductive loads such as motors, transformers, and solenoids by allowing higher inrush currents without nuisance tripping while ensuring rapid fault clearing. The unit delivers a 10kA interrupting rating at both 240V AC and 48V DC, meeting UL 489 standards for safety and reliability. It features a turn-to-reset (RTT) actuator for easy manual operation and reset after tripping. The integrated ring cable lug connection simplifies wiring and ensures secure terminations in panelboard and control cabinet installations. With a power loss of 4.5W per pole at rated operating conditions, the SU201MR-K40 is optimized for energy efficiency and thermal performance. Designed for modular DIN rail mounting, this ABB MCB is part of the SU200MR series, offering consistent performance and compatibility with standard industrial electrical systems. The compact design and durable construction make it suitable for space-constrained installations while maintaining robust operational reliability.
