Imashini yamashanyarazi ya WTB1Z-125 DC ni icyuma cyumuzunguruko wa DC gifite umuvuduko wa 125A. Irakwiriye kurenza urugero no kurinda imiyoboro ngufi ya DC, hamwe no guhagarika byihuse hamwe nubushobozi bwo kumeneka bwizewe, bushobora kurinda neza ibikoresho byamashanyarazi nizunguruka kwangirika kwatewe nuburemere burenze urugero nizunguruka. Iyi moderi ya DC miniature yamashanyarazi isanzwe ifata igishushanyo mbonera, cyoroshye kuyishyiraho, guhuza ingano, kandi ikwiranye nagasanduku gafungura ikirere, kugenzura akabati, agasanduku ko kugabura, nibindi bihe.
WTB1Z-125 kumeneka hejuru ca pacity umuzunguruko utanga ibice byizuba PV syste m. Ibiriho ni form 63Ato 125A na voltage kugeza 1500VDC. Ibipimo ngenderwaho ukurikije IEC / EN60947-2
