From general applications to special applications, Siemens offers a wide range of overload relays that provide superior motor protection. Overload relays are used to protect motors from excessive heat resulting from sustained motor overloads, rapid motor cycling, stalled rotor conditions and phase loss.
ESP200 Solid-State Overload Relays, Class 48, 958 and 958L
The ESP200 overload relay is so simple to configure
Thermal Overload Relays, Class 48
Self-powered ESP200 overload relays provide accuracy unmatched in the market. With repeat accuracy of greater than 99%, trips can be set to the most specific conditions, resulting in both longer motor life and cost savings.
ESP200 overload relay
The ESP200 overload relay is so simple to configure. No software or manuals are required. If replacing existing installed ESP100 with the new ESP200, no modifications to the contactor, enclosure or MCC compartment are needed.
Ambient compensated bimetal overload relays are designed to compensate for the ambient air temperature surrounding the overload. This helps to prevent the occurrences of nuisance tripping. Additionally, they are automatic or manual reset selectable. Heater elements are required.
