£704.40
The IMO MCOR-6-320 is a high-capacity thermal overload relay designed to provide dependable motor protection for large industrial motors operating in demanding environments. Engineered for use with compatible IMO MC series contactors, this overload relay safeguards motors against overload currents, overheating and phase failure conditions that can lead to equipment damage and production downtime.
As part of the reliable IMO MCOR overload relay series, the MCOR-6-320 combines robust industrial construction with precise thermal protection characteristics. Its adjustable overload settings and durable design make it suitable for motor starter assemblies, MCC panels and heavy-duty automation systems requiring reliable motor protection.
With an adjustable current setting range of 250 to 320 A, the IMO MCOR-6-320 is ideal for protecting large three-phase motors used in industrial pumps, compressors, processing systems, conveyors and heavy machinery. Its direct mounting format enables streamlined integration into industrial control panels and motor control centres.
Thermal overload relays continuously monitor motor current and disconnect the circuit if excessive current or overheating conditions occur. This protection helps prevent motor winding damage, insulation failure and unplanned downtime in demanding industrial applications.
The IMO MCOR series is engineered for industrial motor control systems requiring dependable overload protection and long-term operational reliability. The MCOR-6-320 is particularly suited to larger motors operating under heavy load and continuous-duty conditions.
