The WSB1Z-63 is a 6kA double-pole DC miniature circuit breaker for solar photovoltaic systems. Rated up to 63A and 500V DC, it provides overcurrent and short-circuit protection on the DC side of PV installations, suitable for solar combiner boxes, inverters, and DC distribution panels.
The WSB1Z-63 is a 6kA double-pole DC MCB rated up to 63A and 500V DC. It handles overcurrent and short-circuit protection on the DC side of photovoltaic systems, commonly installed in solar combiner boxes, inverter inputs, and DC distribution panels.
The WSB1Z-63 is a 6kA double-pole DC miniature circuit breaker rated up to 63A. It operates in DC circuit systems at four standard voltage levels: 250V, 500V, 750V, and 1000V DC, covering most residential and commercial PV installations.
The breaker protects against overload and short-circuit conditions on the DC side of photovoltaic systems. A double-pole design isolates both positive and negative conductors simultaneously, which is required by most solar installation codes for DC circuit protection. It also supports infrequent manual switching for maintenance and circuit isolation.
Typical applications include solar combiner boxes, inverter DC inputs, battery charge controllers, and DC distribution panels. The product is widely used in rooftop PV systems, solar farm sub-arrays, and off-grid power setups in commercial and residential buildings.
Complies with GB 10963.2 and IEC 60898-2. Available in 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, and 63A ratings. DIN rail mounting, standard 35mm profile.
