It requires a build‑in panel mounting method with a 22mm circular cut‑out and is retained by its front‑mounted bezel.

The mechanism employs a turn‑to‑reset action where the head must be rotated to release the latched stop condition.

The unit uses spring‑clamp terminals that accept conductors for efficient, tool‑assisted termination.

The head is a 40mm diameter round style that provides a larger surface for actuation while wearing protective gloves.
