Note% Rating Power(1) When specifying the terminal as insulated wires,
please specify the wire length in mm, such as FL300.
(2) If the terminal designation is left blank, it will be ametal terminal (quick connect or 3.2Φ metal terminal).
(3) Screw hole terminal holes are not cut, so connect
them with bolts and nuts.
(4) Be sure to specify the insulation withstand voltage. If
not specified, the dielectric strength is 1500VAC.
(5) A thermostat element can be built in the resistor.
Please contact info@nikkohm.co.jp.
(6) For reliable specification, please request aprocurement specification or product specification toinfo@nikkohm.co.jp.
(7) For the marking on the resistor surface of UL
certified, the manufacturer code is not the N mark but theRARA mark of the UL certified applicant.
(8) County origins at South Korea.
