A magnetic resonance apparatus is proposed. The magnetic resonance apparatus has a magnet unit, magnet housing and a housing unit surrounding the magnet unit. The housing unit includes at least one support structure unit and a cladding unit. The cladding unit has at least one first layer, which includes a sound absorption element, and at least one second layer, which includes a heavy mass layer.

Magnetic resonance apparatus with sound absorption cladding and irregular grid

A magnetic resonance apparatus includes a magnet unit and a housing unit enclosing the magnet unit. A noise prevention unit is provided which is arranged between the magnet unit and the housing unit enclosing the magnet unit and which has at least one noise prevention element made of an insulating foam. The at least one noise prevention element has a D-shaped cross-sectional area.

A switching unit for an electrical switching device, in particular an electrical circuit breaker, is disclosed. The switching unit includes a switching lock with a switching mechanism and a rotor housing with a contact arm disposed therein for opening and closing contacts during a rotation of the rotor housing about a rotation axis. In an embodiment, at least one lever apparatus is functionally connected at its upper end by way of the switching mechanism and at its lower end by way of a connecting pin to a face of the rotor housing.

Switching unit for an electrical switching device

A switching device include at least two switching poles. Each of the switching poles has one current path and one switching contact system for opening and closing the current path, wherein a movable contact arrangement of the switching contact system of the switching poles has an integral switching shaft segment, formed from insulating material, which bears a contact lever arrangement and in which the switching shaft segments of adjacent switching poles are connected by way of at least two connecting branches; so as to form the switching shaft. The connecting branches extending at a distance parallel to the axis of rotation and are formed from corresponding connecting elements. In at least one embodiment, all of the connection elements of the at least two connecting branches are formed by first sections of the integral switching shaft segments, which bear the contact lever arrangements.

Multipole electrical switching device

A circuit breaker is disclosed, in particular for low voltages, having a switch shaft and a contact lever rotationally mounted and extending transverse to the longitudinal axis of the switch shaft and protruding out of the switch shaft, the shaft carrying a movable contact on a side of the outer contour of the contact piece, and including a recess on the opposite side of the outer contour thereof for suspending a pin having a force applied thereto on both sides of the contact lever by way of one spring each, each applying a torque to the contact lever in the closing direction. The two springs each include a cover element extending along the spring and each disposed between the spring and the arc formed between the contact pieces when the circuit breaker is opened.

Circuit-breaker, in particular for low voltages

An electric switch is disclosed. In at least one embodiment, the switch includes a rotor housing; at least one electric contact arm, rotatably mounted in the rotor housing and being pivotable between an on-position and an off-position as well as relative to the rotor housing; and at least one intermediate part which, in a locking position, locks the pivotable contact arm with the rotor housing and, in the event of a relative rotation between the pivotable contact arm and the rotor housing, is moved away from the predefined locking position.
