Overcurrent circuit breaker 15kA FAZ DC FAZ-B2/2-DC 176075

DC Overcurrent Switch – Reliable Installation Protection

This two-pole overcurrent switch from Eaton's FAZ series is a key element in protecting direct current (DC) circuits. Designed to operate in systems up to 440V, it effectively protects against the effects of overloads and short circuits, ensuring the safety of the installation and equipment. The B characteristic means the switch reacts quickly to current increases, but also allows for short-term peak loads, which is particularly important in applications with motors or other loads with high inrush current.

Application and design features

The FAZ-B2/2-DC switch finds wide application in photovoltaic installations, emergency power systems and other applications using direct current. Its compact housing, 2 modules wide, allows for easy mounting in switchboards. The rated short-circuit breaking capacity of 10kA at 230V and 400V guarantees effective protection even in the event of serious disturbances. Made of high-quality materials, it ensures durability and reliable operation for a long time. The cross-section of the connected cable up to 25mm² provides flexibility in choosing cables matched to the load.
