    tripswitches for fusing drives

    I have servos which draw just over 2 amps during normal use, and 6 amps at stall. Ideally i want to limit the supply to the drives so that should they stall the drives will cut out. Are normal domestic trip switches suitable for this task (the din rail ones used in fuseboxes)?

    Do you mean 6amps under load? What kind of drives do you have?
    If torque mode drive, the current should be zero when stationary, unless they are being backfed loaded somehow.
    Most drives have a current limit setting for this kind of protection.

    i mean 6 amps draw at stall torque. The drives are torque control, and have overcurrent protection, but the closest i can get is 4A limit. Is it ok to just rely on this?

    Usually the current limit setting is the first line of defence.
