DIHOOL 320 Amp DC Circuit Breaker,2P 1000V 20kA Breaking Capacity Battery Disconnect Switch with Thermal Magnetic Trip for Solar, UPS, Battery

**** The large, heavy-duty circuit breaker has garnered mixed reactions from customers, particularly due to its robust Construction and significant application within solar energy systems. Users generally commend its solid build quality, with one reviewer highlighting its appropriateness for off-grid solar installations. The 500 amp version appears to be especially favored among customers looking for reliability and durability in their energy setups. However, there are concerns regarding the lack of clarity in the product description, particularly regarding the directional functionality of the breaker. Several customers expressed apprehension about whether the breaker is bi-directional which could potentially pose safety risks, especially in scenarios involving short circuits on either the inverter (load side) or the battery (supply side). This points to a vital Consideration for buyers, particularly in regions with stringent safety regulations, like Australia, where non-bidirectional breakers have faced bans due to fire hazards associated with battery shorts. Additionally, some practical installation challenges were mentioned. Users found it difficult to mount the breaker on flat surfaces and noted that the product sometimes came missing necessary components, such as nuts for installation, further complicating the process. While the initial quality of the device is generally praised, the lack of sufficient and secure packaging has raised some issues about damage during transit. Overall, while the circuit breaker holds potential for high performance in demanding environments, customers advise potential buyers to verify specifications related to directionality and ensure they are fully equipped for installation. **
