Miniature Circuit Breakers (MCB)

Protection for Everyday Electrical Systems

The SENTRY Series Miniature Circuit Breakers (MCB) are designed to provide efficient protection against overload and short-circuit conditions in low-voltage electrical applications. Built with robust performance standards, they offer flexible pole configurations, multiple tripping curves (B, C, D), and high breaking capacity up to 10 kA. With durable mechanical and electrical life, DIN rail mounting compatibility, and compliance with IEC 60898-1 standards, these MCBs ensure safe, consistent, and long-lasting circuit protection across residential, commercial, and industrial installations.
