A distribution block for attaching to a support rail extending in a support direction comprises an insulating housing, and a conductive member arranged in the insulating housing. A mounting assembly of the distribution block is connected to the insulating housing for attaching to the support rail. The distribution block is mountable on the support rail in a longitudinal configuration wherein the extension direction of the insulating housing is substantially parallel to the support direction, and in a transverse configuration wherein the extension direction of the insulating housing is transverse to the support direction.

An electrical distribution block includes a first base, a second base, and a spacer plate discrete from the first and second base. The spacer plate is positioned between first base and the second base and secures the first base to the second base. A conductor block is connected to at least one of the first base or the second base. The conductor block includes a primary tap and a secondary tap.

A bus device of a terminal block includes a case and a latch assembly. The case has a connecting side and is formed with a sliding trough. The latch assembly includes an actuator and a locking peg. The actuator is disposed in the sliding trough and movable along the sliding trough between a release position and a locking position. The actuator has an actuating ramp set. The locking peg is axial-rotatably disposed in the case and arranged corresponding to an end of the sliding trough. An end of the locking peg projects from the connecting side and has an inverted hook. The locking peg has a protrusive key abutting against the actuating ramp set. When the actuator moves between the release position and the locking position, the actuating ramp set is configured to push the protrusive key to axially rotate the locking peg.

A current bar adapter for electrically connecting at least one plug-in module to at least one current bar and/or contact bar of an insert part which is inserted into a mounting rail, a number of current bars and/or contact bars that extend in a longitudinal direction of the mounting rail being arranged in the insert part, the current bar adapter including: a clamping device for snapping the current bar adapter onto the mounting rail; at least one interface for contacting the at least one plug-in module; and at least one contact element for contacting the at least one current bar and/or contact bar and establishing an electrical connection between the current bar and/or contact bar and the at least one plug-in module.

A luminaire (30) or electrical unit for connection to a supporting rail (10) has a contacting element (40, 50, 60), which is introducible into the supporting rail profile (15) and has connection contacts (42, 52, 62) mounted adjustably in order to bear against lines (25) of the busbar (20) in a state in which the contacting element (40, 50, 60) has been inserted into the supporting rail profile (15). The contacting element (40, 50, 60) has at least one contact block (41, 42, 51, 52, 61, 62) with connection contacts (43, 53, 63), which is linearly laterally adjustable between an open position and a contacting position.

A circuit interrupter adapted to be detachably connected to a rail system includes a housing having a notch disposed thereon adapted to receive a first leg of the rail system. An engagement member having a notch disposed therein adapted to receive a second leg of the rail system is slideably carried by the housing such that the notch in the engagement member is moveable in a first plane toward and away from the notch in the housing between an engaged position and a disengaged position. An actuation member is slideably carried by the housing and is moveable in a second plane, different than the first plane, between an actuated position and an unactuated position, movement of the actuation member in the second plane being translated into movement of the engagement member in the first plane.

A fixing system includes a rail fixture having a plurality of first interlocking devices arranged along the rail fixture and a plurality of interlocking modules each having a second interlocking device. The interlocking modules are affixed to the rail fixture by inserting the second interlocking devices through a plurality of gaps between the first interlocking devices and sliding the interlocking modules along the rail fixture into a positive lock.
