Available for 480VAC

We have expanded our lineup of products for 480VAC. Products for 480VAC, which is on the rise for overseas projects, etc., are now supported. All models, including molded case circuit breakers (NV) with earth leakage protection, can be used on 480VAC circuits.

Significantly Increased Breaking Capacity

The H Class with significantly increased breaking capacity has been additionally added to the lineup. Requirements are met for SCCR (short-circuit current rating) in North America.

UL Certification Obtained for 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. (Excluding under voltage trip devices (UVTs))
