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.

A DIN rail device mount system includes a base, a module and a locking mechanism. The base is configured to be mounted on a DIN rail. The base defines a receiver slot. The module is configured to be removably mounted in the receiver slot to form a DIN rail mount assembly. The locking mechanism includes: a lock member having opposed proximal and distal ends and including an integral lock member latch feature on its distal end, wherein the lock member is pivotally connected to the base at its proximal end to pivot between a closed position and an open position; and an integral module latch feature on the module. The DIN rail mount system is selectively positionable in each of: a locked configuration wherein the module is seated in the receiver slot, the lock member is in the closed position, and the lock member latch feature is interlocked with the module latch feature, whereby the lock member secures the module in the receiver slot; and an unlocked configuration wherein the lock member is in the open position, the lock member latch feature is not interlocked with the module latch feature, and the module can be withdrawn from the receiver slot.
