Product Overview

Protecting industrial motors from dangerous thermal overloads, the Siemens 3RU2136-1KB0 thermal overload relay provides reliable current-based trip protection. Overload relays of this type are routinely installed in control panels downstream of contactors to interrupt control circuits whenever excessive current draws persist over time, preventing motor winding damage. Pricing, availability, and lead time are confirmed per enquiry through an RFQ.
