TOMZN TOB7Z-63 32A 2P 1000V DC Solar MCB

Product Identification

Product Title

TOMZN TOB7Z-63 32A 2P 1000V DC Solar MCB

Short Description

The TOMZN TOB7Z-63 is a 32A, two-pole DC miniature circuit breaker intended for compatible photovoltaic DC circuits. The official TOMZN product page confirms the TOB7Z-63 series, 2P configuration, 1000V DC rating and availability of the 32A variant. Product-label markings show a 6kA breaking-capacity claim and IEC/EN 60947-2 reference; an official downloadable datasheet or certificate for those markings was not found.

Long Description

Designed for DC-side switching and circuit protection in suitably engineered solar installations, the TOMZN TOB7Z-63 combines a two-pole linked operating handle with polarity-marked terminals in a compact modular enclosure. This listing is for the 32A, 2P, DC 1000V version identified on TOMZN's official product page.

The breaker is suitable for use only where its voltage, current, polarity and system fault-current requirements have been checked by a qualified installer. The supplied reference image carries Icu 6kA, IEC/EN 60947-2 and CE markings; because TOMZN did not provide a downloadable official datasheet or certificate on the identified product page, these details are presented as product-label observations rather than independently certified claims.

Technical Specifications

Applications

• Residential solar PV DC distribution

• Commercial solar PV DC distribution

• PV string protection where the design requires a compatible 32A two-pole DC MCB

• Solar combiner boxes with compatible ratings

• DC-side isolation between PV circuits and compatible inverter equipment

• Other engineered DC circuits only after voltage, current, polarity and fault-current coordination

This breaker must not be selected solely by current rating. The complete DC system design, conductor rating, prospective fault current, polarity and isolation requirements must be verified by a qualified electrical professional.
