Abstract
A thermal overload relay comprising a change-over spring mechanism and a contact mechanism that is separated from the spring mechanism. The contact mechanism is actuated by the spring mechanism, which is driven by a bimetallic strip when an overcurrent flows through the strip. The spring mechanism has no electrically conducting portion. The change-over point of the spring mechanism varies only a little, thus enhancing the reliability. The spring mechanism is easy to assemble and adjust.
