Product Title

TOMZN TOB7Z-63 20A 2P 1000V DC Solar MCB

Short Description

The TOMZN TOB7Z-63 is a 20A, 2-pole DC miniature circuit breaker designed for solar PV and other compatible DC circuits. The supplied unit is marked for 1000V DC, 6kA ultimate short-circuit breaking capacity, and IEC/EN 60947-2, with linked double-pole operation and clear polarity markings.

Long Description

Protect and isolate compatible DC circuits with the TOMZN TOB7Z-63 20A 2P DC MCB. Its linked two-pole handle disconnects both poles together, while the printed polarity diagram supports correct DC wiring. The compact modular body, screw terminals and visual status windows make it suitable for professional solar distribution and control panels.

The photographed 20A variant is marked for a maximum rated voltage of 1000V DC and an ultimate short-circuit breaking capacity of 6kA. It is intended for correctly engineered PV and DC installations in which the system voltage, prospective fault current, cable size, polarity and coordination have been verified by a qualified installer.
