Why SENTRON RCD?

SENTRON residual current protective devices interrupt dangerous fault currents fast—protecting people, equipment, and uptime in modern installations with complex loads. Engineered for residential, commercial, and industrial use, the portfolio scales from basic RCCBs to advanced, universal‑sensitive solutions.

Portfolio highlights:

  • RCCB (Types AC, A, F)
  • RCBO incl. compact 1 MW 5SV1
  • Type B and B+ universal current‑sensitive devices
  • Selective Type S, super‑resistant Type K, SIGRES for harsh environments
  • Add‑on RC units and accessories (remote mechanism, auxiliary contacts)
  • Modular residual current & measuring devices (e.g., 5SV8)

Key benefits

Deliver proven safety

Electromechanical RCDs trip independently of line voltage and address complex residual currents to minimize electric shock and fire risk across applications.

Reduce unplanned downtime

Selective and circuit‑level protection helps avoid nuisance trips and isolates faults so healthy circuits stay energized, boosting availability.

Accelerate installation and retrofit

Compact 1 MW RCBOs free up space and fit existing boards; a unified accessory system streamlines wiring and upgrades.

Featured capabilities

Detect all relevant fault‑current types

Coverage for Types AC, A, F, B, and B+ safeguards standard and frequency‑converter loads, including smooth DC and high‑frequency leakage.

Combine functions in one device

RCBOs merge residual‑current and overcurrent protection; pair with AFDD to add arc‑fault protection in just two modules.

Enable monitoring and control

Optional RC units, auxiliary switches, and residual‑current measuring devices support remote actuation, signaling, and preventive maintenance.
