ABB GDC801B101 3BHE051592R0101 CROWBAR BOARD

The ‌ABB GDC801B101 3BHE051592R0101 Crowbar Board‌ serves as a protective device in power electronics and drive systems,

primarily for:

Overvoltage Clamping‌:
Instantly shorts excessive voltage spikes (e.g., in DC links or thyristor circuits) to protect components like IGBTs or capacitors.
Fault Current Diversion‌:
Triggers during faults (e.g., grid surges) to redirect energy to a safe discharge path (e.g., resistors or ground).
System Safety‌:
Ensures controlled shutdowns by activating thyristor-based switches when thresholds are exceeded.
Redundancy & Reliability‌:
Designed for fail-safe operation in critical ABB systems (e.g., HVDC converters or industrial drives).

Key Features‌:

Microsecond-level response time.
Compatible with ABB’s control platforms (e.g., PCM600 for configuration).
Rated for harsh environments (e.g., 0–55°C operating range).
