NY60A MNY60A Series
Nihon Kōsokudō's complete electromagnetic circuit breaker New-FM wiring circuit breaker NY60A MNY60A series
[2023 Discontinued Product] [Replacement] Fully Electromagnetic Circuit Breaker 'New-FM Series NY60A / MNY60A'
[Recommended alternative models: We recommend 100A frame circuit breakers with a rated current of 60A for each circuit breaker.] If you have any questions or concerns, please contact the Sales Department of Nikkou Electric Manufacturing Co., Ltd. at 044-455-1211. Nikkou Electric Manufacturing's "New-FM Series NY60A / MNY60A" is a 60AF wiring circuit breaker that employs a fully electromagnetic (oil dashpot type) mechanism for the tripping function. It features stable tripping characteristics that are not affected by temperature changes within the panel, and allows for immediate re-energization after tripping. We offer two models: the "NY type" for wiring protection and the "MNY type" for motor protection.

basic information
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.

Line up（2）
| Model number | overview |
|---|---|
| NY60A Series (NY62A NY63A) | Used for short-circuit and overload protection of main lines and branch circuits in distribution boards and sub-distribution boards for wiring protection (economical type and general-purpose type). |
| MNY60A(MNY63A) | The motor protection circuit breaker (motor breaker) does not operate during the large inrush current at startup, but it is equipped with motor protection characteristics (M characteristics) that reliably detect and interrupt overloads, locked rotor currents, and short circuit currents during operation. |
