The Multiquip EE50903 Auxiliary Switch ABB S500 Series Breakers is a genuine OEM component designed for S500 series equipment. Sourced directly from Multiquip, this part meets the exact specifications required for correct operation within the breaker assembly. Verified fitment for S500 series machines means you can order with confidence and get the right part the first time.

Key Features

  • Correct Electrical Specification — Manufactured to OEM electrical tolerances, ensuring proper signal output and switching behavior within the ABB S500 Series breaker circuit.
  • Direct-Fit Installation — Designed to mount and connect exactly as the original, with no reworking of wiring harnesses or mounting hardware required.
  • S500 Series Compatibility — Confirmed fitment for Multiquip S500 series equipment, eliminating guesswork when sourcing electrical components.
  • Maintains Circuit Integrity — A functioning auxiliary switch accurately signals breaker status to the control system; a failed unit can cause incorrect readings, nuisance trips, or loss of monitoring capability.
  • Genuine OEM Quality — As an authentic Multiquip part, this part is held to the same contact rating and durability standards as the original component it replaces.

An auxiliary switch is a secondary switching element mounted on a circuit breaker that mirrors the breaker's open or closed position. It provides a feedback signal to a control panel or monitoring system, allowing operators and automated controls to know the real-time status of the breaker without direct visual inspection. When an auxiliary switch fails or wears out, the control system loses accurate breaker-status feedback, which can compromise safety monitoring, automated sequencing, or remote indication functions that depend on that signal.
