• Depth (Length): 7.6 in
• Height: 4.25 in
• Width: 4.9 in
• Weight: 4.25 lb

Safety & certifications

• UL Listed (refer to Eaton datasheet and markings for exact UL file/reference)

Features & typical applications

• Magnetic‑only trip provides reliable short‑circuit and locked‑rotor protection for motors where separate overload protection is provided by other means (e.g., thermal relays or electronic motor protection).
• Ideal for industrial motor control, NEMA size 4 starter installations, and applications requiring a robust, compact MCP with stainless steel terminations.
• Line and load rated terminals simplify wiring and replacement.

Ordering & installation notes

• Confirm coordination with upstream protection and downstream motor overload devices; magnetic trip range 450–1500 A must be set/selected in accordance with motor locked‑rotor current and system coordination practices.
• Observe manufacturer installation instructions and torque specifications. Use only Eaton‑specified accessories and mounting hardware for compliance and safety.
• For full electrical curves, adjustment instructions, recommended accessories, and installation details consult the Eaton HMCP product datasheet and installation manual.

Datasheet & support

• Refer to Eaton official datasheet for HMCP series and the HMCP150T4S catalog entry for complete technical data, performance curves, and UL references.
