Product Overview
The Sigma F+E 2.0 is a combined short-circuit and earth-fault indicator for cable networks, developed by HORSTMANN. The device measures current via three single-phase current sensors and provides phase-selective fault detection for short circuits and earth faults. The Sigma F+E 2.0 offers both fixed trip values and a self-adjusting short-circuit detection depending on the operating current.Features
- Phase-selective fault indication with three single-phase current sensors.
- Short-circuit trip values: 200, 300, 400, 600, 800, 1,000 and 2,000 A.
- Earth-fault trip values: 20, 40, 60, 80, 100, 120 and 160 A.
- Trip delays: Short circuit 40 or 80 ms; earth fault 80 or 160 ms.
- Option for self-adjustment of short-circuit response relative to operating current (IB).
- Reset via push-button, remote reset or automatic time-based reset (1, 2, 4 or 8 hours).
- AC/DC variant with external auxiliary voltage 24–230 V AC/DC as well as transformer-powered version.
- Internal long-life lithium cell (lifespan ≥20 years) and in AC/DC variant capacitor backup up to 8 hours.
Typical Applications
- Used in underground cable networks for the detection and indication of short circuits and earth faults, including phase-selective identification.
