High reliability unaffected by ambient temperature Unlike bimetallic (thermodynamic) types, a fully electromagnetic design using an oil dashpot is adopted. It operates accurately at the set current value even in harsh environments with high or low temperatures inside the control panel. Immediate re-engagement after tripping is possible Since there is no need to wait for the bimetal to cool down, it can return to the field and restart immediately after eliminating the overcurrent factor. This contributes to reducing equipment downtime. Application-specific lineup for wiring protection and motor protection NY60A series (NY62A / NY63A): Overload and short-circuit protection for main and branch circuits (2P / 3P) MNY60A series (MNY63A): A type that also serves as three-phase motor protection compatible with starting inrush current (3P) Robust design resistant to aging changes The damper mechanism inside the sealed cylinder maintains stable operating delay characteristics even after long-term use.
