TOMZN TOB7Z-63 63A 2-Pole 1000V DC Solar Circuit Breaker

Short Description

The TOMZN TOB7Z-63 is a 63A, two-pole miniature circuit breaker designed for DC circuits up to 1000V. TOMZN lists the series for photovoltaic systems, while the supplied product label identifies a 6kA ultimate breaking capacity and IEC/EN 60947-2 marking.

Long Description

The TOMZN TOB7Z-63 provides compact two-pole circuit protection for compatible high-voltage DC installations. TOMZN’s official product page identifies this model as a 2P, 1000V DC solar miniature circuit breaker and lists 63A among the available current ratings.

The regional TOMZN product page states that the breaker is intended for overload and short-circuit protection and may also be used for infrequent operation of the line. Listed application areas include photovoltaic systems and communications DC circuits.

The supplied 63A product image shows a mechanically linked blue operating handle, two green status windows, four screw terminals, polarity markings, Icu 6kA, IEC/EN 60947-2 and CE markings. Correct DC polarity, circuit voltage, prospective fault current, cable size and protection coordination must be confirmed by a qualified installer before installation.
