The present invention discloses a unit rack for power storage which can configure a power storage apparatus having a desired capacity through series or parallel connections. The unit rack for power storage of the present invention comprises a plurality of cell modules which are series- or parallel-connected with each other by connection lines; a housing for accommodating the cell modules; a receiving part of a circuit breaker, formed or installed in the housing, and having a ground clearance higher than the highest ground clearance of the cell modules; a circuit breaker received in the receiving part and connected between the connection lines; and a receiving part cover for closing the receiving part of the circuit breaker. [0002] In accordance with the present invention, the unit rack for power storage having a circuit breaker installed therein is used in a high-capacity power storage apparatus to decrease the voltage of the power storage apparatus, even if the power storage apparatus is waterlogged as its installation place floods, thereby improving the safety of the power storage apparatus.
