Low-voltage Circuit BreakersUL 489 Listed Circuit Breakers
WS-V Series
Contributes to Making Machinery Compact
The industry’s smallest class dimension of 54mm in width is used to contribute to making machinery compact.
(Applicable models: NF50-SVFU, NV50-SVFU)
Having standard compatibility with IEC 35mm rails makes it optimal for control panels with multiple circuit breakers aligned on branch circuits.
Available for 480VAC
We have expanded our lineup of products for 480VAC, which are on the rise for overseas projects, etc.
(Applicable models: NF/NV125-SVU, NF/NV125-HVU, NF/NV250-SVU, NF/NV250-HVU)
The breaking capacity has also been greatly increased to meet the demand for higher SCCR (short-circuit current ratings) in North America.
Realizing the Common Use of Attachments
The common use of attachments such as AL (alarm switch), AX (auxiliary switch), SHT (shunt trip device), and UVT (under voltage trip device) between different ampere frames is made possible, contributing to delivery time response and inventory reduction when specifications are altered.
(excluding NF50-SVFU and NV50-SVFU)
Emergency Shutdown Circuit Configuration is Possible
SHT (shunt trip device) can also be installed in molded case circuit breakers with earth leakage protection, making it easy to configure emergency shutdown circuits.
Can be Supplied as Stand-alone Attachments
Since UL certification is obtained at the attachment level, the components can be supplied as stand-alone attachments. Installation and replacement work can be done by the customer in case of sudden alterations in specifications.
