Engineered for commercial and industrial applications, this 20A miniature circuit breaker delivers reliable branch circuit protection. It handles moderate inrush currents typical of modern control circuits. The unit mounts securely onto standard DIN rails within industrial control panels. It serves as a drop-in replacement for the legacy 1489-A1C200 model. Rated at 10kAIC at 277VAC, this thermal-magnetic breaker features current-limiting capabilities and reversible line and load connections.
