Protection against thermal overload of the braking resistor

INFORMATION

A PTC braking resistor becomes highly resistive in the event of an overload.

INFORMATION

Flatpack resistors have internal thermal protection (fuse cannot be replaced) that interrupts the current circuit in the event of overload. The configuration guidelines and the documented assignments of the drive inverter and braking resistor must be adhered to.

• Parallel connection of braking resistors
• Internal temperature switch -T
• External bimetallic relay
