Abstract: A circuit breaker system has a circuit breaker with a circuit breaker communication unit. A display unit contains a display housing, and the circuit breaker and the display unit are configured such that the display unit is latched to the circuit breaker. The circuit breaker and the display unit, in the latched state, are connected to one another by a plug connection, such that data of the circuit breaker are displayable on the display unit. A display holder is provided, containing a holder housing and a holder communication unit. The display holder is configured such that the display unit can be latched into the display holder, that the display holder and the display unit, in the latched state, are connected to one another by an electrical plug connection, and that the display holder is configured such that the data of the circuit breaker are displayed in the latched state.

Abstract: The invention relates to a circuit breaker for a low-voltage circuit having input and output terminals for conductors of the low-voltage circuit. Within the circuit breaker, the low-voltage circuit can be interrupted or closed. The circuit breaker also has a current sensor which determines the level of the electrical current in the low-voltage circuit and is connected to an electronic trigger unit which has a display for displaying information and interrupts the low-voltage circuit if current limit values or current-time limit values are exceeded. The display is designed to be removable.

Abstract: A circuit-breaker includes an electronic trip unit, which initiates an interruption or reduction of the current flow in a low-voltage circuit when current or current-time limits are exceeded in the low-voltage circuit. The electronic trip unit includes at least two processors that independently check whether current or current-time limits are being exceeded. A test signal is fed to the circuit-breaker via a first communication interface, which is fed to one of the two processors during operation so that a test of the circuit-breaker is carried out during operation, while at the same time an active protection is provided with regard to the exceeding of current or current-time limits.

Abstract: A system and method for operating an indoor/outdoor drone in a training mode that limits the maximum altitude during flight, restricts the ability to perform rapid maneuvers, and also may disable the ability to conduct aerial stunts. The system includes a flight controller that may select between the training mode, a normal mode, and a stunt mode. In the training mode, the flight controller restricts an increase in altitude of the drone beyond an altitude threshold, and also restricts an increase in one or more movement parameters of the drone beyond respective movement parameter thresholds. The selection of the training mode may disable the ability for the user to select the stunt mode.

Abstract: A display unit and an installation are disclosed for distributing electrical energy. In an embodiment, a display unit includes a plurality of switches. The display unit is connected via a communication link to the switches and is configured to receive data relating to the operation of the switches. Each switch of the installation comprises two mechanically disconnectable switching elements, a sensor unit to detect the current flowing over the switching elements, an electronic trip unit to initiate the disconnection of the switching elements if a trip condition allocated to the switch is fulfilled, and a mechanical switching unit to disconnect the switching elements if the trip condition is fulfilled.

Abstract: The assembly comprises a flat pallet of extended surface area and a plurality of knock-off caster devices of improved type releasably secured to the pallet. Each caster device includes upper and lower horizontal plates joined at one end by a vertical web to form a sleeve in which an edge or end of the pallet is releasably secured by anchoring spikes, nuts or the like. A caster bracket is secured to the underside of the lower plate and a rotatable caster depends therefrom. A flange, detent or the like is provided to facilitate knock-off of the caster device from the pallet when the device is no longer needed. Preferably, the caster device is adjustable in plate length, sleeve height and/or caster position. The device may include a type which has a pair of casters, brackets and sleeves on opposite ends of the lower plate, which is adjustable to span the pallet. In a second type, the lower plate spans the pallet and has an upturned end abutting the pallet end and bearing a flange.
