Description
TeSys LRD thermal overload relay, 24A/690V, thermal setting range
16-24A, tripping class 10A, for protection of 3-phase motors 11kW@400V.
Differential device with phase failure and load unbalance detection. It
provides a thermal adjustment dial, a manual-automatic reset selector, a test
selector for simulation of a trip, reset and stop buttons, a flag indicator,
and 2 auxiliary contacts (1NO and 1NC) for fault signaling. Settings are
protected by a transparent cover lockable by sealing. Connection by screw clamp
terminals: it connects directly to the bottom terminals of 3-pole contactors
