fräsmaschine die in den staaten steht. wir "basteln" da grad an der ul zulassung. und natürlich gabs da einige mängel. das meiste nur kleinkrams. aber ich (wir) verstehen da irgendwie was nicht, unsere englisch freaks scheitern an den ganzen fachbegriffen. und zwar gehts um
siemens motorschutzschalter.

Both of the devices have the UL marking. What do you mean by “not suitable for branch circuit protection”?Please explain more detailed

You are correct, however, please read the label marking carefully. These devices are UL Listed as Manual Motor Controllers and Self-Protected, Combination Motor Controllers. In order to qualify these devices as a self-protected, combination motor controllers, there are accessory components that must be used. These components are indicated on the label. The standard (UL 508A) authorizes the use of self-protected combination motor controllers for branch circuit protection (short circuit, overcurrent and overload). Branch circuit is defined as conductors and components following the last overcurrent protective device protecting a load. The following marking must be applied if a self-protected device is used:
WARNING -- To maintain overcurrent, short-circuit, and ground-fault protection, the manufacturer’s instructions for selection of overload and short circuit protection must be followed to reduce the risk of fire or electric shock.
WARNING -- If an overload or a fault current interruption occurs, circuits must be checked to determine the cause of the interruption. If a fault condition exists, the current-carrying components should be examined and replaced if damaged, and the integral current sensors must be replaced to reduce the risk of fire or electric shock.

The following device is listed as manual motor controller only. These devices are not suitable as a branch circuit protection, device per the standard:Siemens 3RV1011 (0Q1, 0Q14, 0Q13, 0Q12.1, 0Q12, 0Q21, 0Q20, 0Q2, 0Q4, 0Q4.1, 0Q3, 0Q3.1, 0Q5, 0Q6, 0Q7, 0Q10, 0Q11)
These devices are UL Listed but only as manual motor controllers. Please review the label. They are not suitable as branch circuit protection devices per the Standard. They must be replaced.
wäre klasse wen mir da jemand n tip geben könnte.
