TeSys thermal protection three-pole relays
Range of TeSys thermal relays for motor protection.
Compensated, with automatic or manual reset, and trigger display.
Equipped with test function.
To be mounted on LC1 type contactors from the TeSys range.
No direct fitting on old contactors (add panel ) for refs. LRD01 to LRD35.
Possible to use pre-wiring kit and assembly support for DIN rail.
