The Omron J7MN-3P-17 is a robust Motor Protection Circuit Breaker (MPCB) designed to safeguard electric motors from overloads and short circuits. This model operates with a rated current of 17A and offers a thermal overload release setting range adjustable from 11A to 17A.
Key electrical characteristics include a high short circuit breaking capacity of 221 kA at 400V, ensuring safety during fault conditions. It adheres to CLASS 10 motor protection standards, providing reliable protection for motors up to 7.5 kW at 400V. The device also features a fixed short-circuit release set at 13 times the nominal current (13 x Iu) and a switching capacity of up to 100 kA/400 V.
This MPCB system is built for durability and ease of use, fulfilling all necessary industry standards. Options such as ON/OFF indication, trip alarm/indication, undervoltage release, shunt release, and three-phase busbar systems are available to enhance functionality and integration into various industrial control panels. Moulded plastic enclosures and door coupling rotary mechanisms are also offered for specific application needs.
