Schneider LR9F5371 Industrial Control Relay TeSys Types Overload Relay Up to 630A For LC1F Contacors
Applications
Electronics harnessed for motor starters. These ingenious electronic overload relays offer a wide current adjustment range and a high level of accuracy due to thermal modeling suitable for even the most demanding applications. They can be directly mounted to TeSys D and F contactors to form extremely compact motor starters.
