ABB T16-1.3 Thermal Overload Relay

ABB's T16-1.3 thermal overload relay is a three-pole, tripolar, bimetallic protective device designed for motor protection in ABB contactor assemblies. It provides adjustable thermal overload protection with a setting range of 1.00 to 1.30 A and a full-load current rating of 1.30 A, aligning with small- to mid-size three-phase motors. This Class 10 relay is intended for 480/600 V AC motor circuits and is part of ABB's T16 series, offering an economical electromechanical protection solution for the main circuit in 3-phase starter systems. When paired with compatible ABB contactors, the T16-1.3 delivers reliable protection against motor overheating while maintaining a compact form factor suitable for panel-mount or integrated starter configurations. The designation T16-1.3 specifies the nominal trip setting and current range, helping technicians select a relay that matches the motor's nominal full-load current and protection requirements.
