Schneider Electric 9001K15 Emergency Break-Glass Operator

Schneider Electric's 9001K15 Emergency Break-Glass Operator is a 30 mm push-button head, Type K, in the Harmony 9001K family, designed for robust industrial control stations needing a clearly visible emergency-stop action. The glass disc holds the button depressed until the disc is broken (typically with a hammer), at which point the button returns to its extended position, and a package of five replacement discs is included with the operator. It features finger-safe contact blocks and light modules to improve security and visibility, plus an automatic self-grounding design that eliminates the need for additional wiring. Replacement parts catalog includes the 9001K57 replacement discs and related hardware such as the 9001K40 top ring nut and yellow bumper components, supporting long-term serviceability.
