Ideal Applications
The TOB7Z-63 can be used in appropriately designed solar PV systems, PV string protection, DC distribution boxes, inverter DC protection and other DC electrical circuits.
A properly rated DC circuit breaker should be selected according to the actual PV string voltage, operating current, short-circuit current and system design. A conventional AC MCB should not automatically be substituted for a DC-rated breaker.
