IEC overload relays provide reliable and accurate electronic or thermal protection from device or component overload or phase loss. Available in various amperage capacities, models are available with configurable parameters, self-powered, and with communications capabilities.
IEC Overload Relays
Category Selection
All motor contactor installations can benefit from overload protection, and can be used to create a complete motor starter. IEC overload relays are available that are designed to work with each offered brand’s contactors, as well as stand-alone units that can be used with any brand or style of contactor. Electronic overloads use microprocessor-based technology to offer precise overload and phase loss protection; thermal overloads offer reliable protection at low prices.
