A surge protective device (SPD) module includes a module housing, first and second module electrical terminals mounted on the module housing, a gas discharge tube (GDT) mounted in the module housing, and a fail-safe mechanism mounted in the module housing. The GDT includes a first GDT terminal electrically connected to the first module electrical terminal and a second GDT terminal electrically connected to the second module electrical terminal. The fail-safe mechanism includes: an electrically conductive shorting bar positioned in a ready position and repositionable to a shorting position; a biasing member applying a biasing load to the shorting bar to direct the shorting bar from the ready position to the shorting position; and a meltable member. The meltable member maintains the shorting bar in the ready position and melts in response to a prescribed temperature to permit the shorting bar to transition from the ready position to the shorting position under the biasing load of the biasing member. In the shorting position, the shorting bar forms an electrical short circuit between the first and second GDT terminals to bypass the GDT.

The wall mountable lighting fixture does not require tools to attach and remove the fixture from a wall surface. The wall mountable lighting fixture includes an attachment mechanism that can be manipulated from a first position to a second position by the push of a button. The button is pressed and the dimension of the attachment mechanism is increased and placed about the edges of a DIN rail attached to the wall. When the button is released, a biasing member returns the attachment mechanism to the first position, thereby reducing the dimension of the attachment mechanism. Once reduced, the dimension is smaller than the critical dimension of the DIN rail and either grips or rests within the DIN rail, thereby holding the fixture to the wall surface. Reversing the steps allows for the removal of the fixture from the wall for repair or replacement.
