Plug with the rated marking of a 1000 A circuit breaker. HWW467H

Rated plug for hw+ 1000A air circuit breaker

The HWW467H plug is the component that connects the Sentinel or Sentinel Energy electronic trip unit to the measurement and control circuit of the hw+ air circuit breaker. It is an indispensable part of systems that require precise diagnostics, real‑time monitoring, or protection configuration via a digital interface.

It does not operate independently – it works only as part of the hw+ system, transmitting data from the trip unit to the Hager Power Touch application via Bluetooth, and also allowing local reset and parameter read‑out. Its function is informational and control‑oriented, not mechanical.

For the installer – practical benefits

• No additional wiring – the plug connects directly to the trip unit, eliminating manual cable connections. Installation takes seconds.

• Advanced diagnostics – when the plug is paired with a smartphone, you can read phase current, temperature, lockout state, trip history, and protection settings without opening the enclosure.

• AUTO‑reset – if the breaker trips due to a short circuit, the plug enables automatic re‑energisation of the system once the fault clears – no need to press the RESET button manually.

• Standard compliance – conforms to IEC 60947-2 and EN 60947-2, ensuring safety and correct operation in low‑voltage installations.

For the end user – what it delivers

• Installation status visibility – without opening the cabinet you can check whether a circuit is overloaded or if a phase is over‑loading.

• Failure prevention – alarms set by the trip unit (e.g., over‑current) appear on the phone, giving time to react before a shutdown occurs.

• Simpler maintenance – the technician no longer has to “play detective”; all data are available digitally. No need to measure current with clamps or manually read nameplates.

The plug is not a protective device. It does not interrupt current or limit short‑circuit currents. It is the “eye” of the system – it reveals what is normally hidden behind the cover, changing the handling of large installations from “reactive” to “proactive”.
