The BCH MC305ANA3F Citation Thermal Overload Relay is a high-performance direct mounting motor protection relay designed to protect three-phase motors against overload, single phasing, and phase imbalance. With an adjustable current setting range of 1.58–2.50A, it provides accurate thermal protection for low-power motors and mounts directly onto compatible BCH Citation contactors.
Designed for industrial reliability, the MC305ANA3F features ambient temperature compensation, field-selectable manual/automatic reset, a test button for trip verification, and a snap-on setting cover to prevent accidental setting changes. It complies with IEC 60947-4-1 standards and supports Type-2 coordination, making it ideal for motor starters, MCC panels, compressors, pumps, and industrial automation systems.
