Eaton xEffect FAZ Miniature Circuit Breaker, 1-Pole, 6A, Type D, 240V ac AC, 48 V dc DC, 10 kA Breaking Capacity

Stop wayward currents in their tracks with this single-pole MCB from Eaton. It's an electrical safety device that protects equipment and people against overcurrents by automatically disconnecting power supplies when faults occur. The unit's rapid short-circuit response minimises rogue loads to reduce downtime. A trip-free mechanism means impatient fingers can't forcibly hold the breaker in the ON position – it can only be reset when the fault is cleared. Simply clip the unit onto a DIN rail for quick and tool-free mounting. It's commonly used to support kit such as medical machinery and UPS systems.

• Thermal-magnetic tripping mechanism for combined protection against overloads and short circuits

With a mounting width of just 17.5mm, you can squeeze this MCB onto busy rails and save space on panels.

A D-curve device like this one is suitable for very high inductive loads as it trips when it receives between 10 and 20 times the rated current. In this instance, that's 6A.
