Toshiba R-20E.3 Thermal Overload Relay

Description:

The Toshiba R-20E .3 Thermal Overload Relay is used in industrial motor control systems to provide overload protection for low-current three-phase electric motors by interrupting the control circuit during sustained overcurrent conditions. Commonly installed in Toshiba magnetic motor starters, motor control centers (MCCs), industrial control panels, conveyors, pumps, compressors, fans, and OEM machinery requiring a 0.3 A overload relay. Maintenance teams, OEMs, and system integrators use this overload relay for replacement of worn protection devices, motor starter repairs, preventive maintenance, and electrical control system upgrades.

Applications:

The Toshiba R-20E .3 is widely used in industrial motor starter assemblies, machine tools, factory automation systems, HVAC equipment, water and wastewater treatment facilities, packaging machinery, and manufacturing equipment where dependable thermal overload protection is required to safeguard low-current three-phase motors from overload and phase-loss conditions.
