Typische Anwendungsszenarien
- 70V DC new‑energy vehicle battery bank short‑circuit protection
- Heavy‑duty special vehicle and mobile equipment DC power distribution
- RV, yacht and marine vessel high‑current DC‑system protection
- Energy‑storage system main‑circuit short‑circuit protection
Match this ceramic high‑temp fork bolt‑down short‑circuit protector with our Verschraubbare Sicherungshalter für die komplette Stromverteilungsanlage.
Installations- und Sicherheitshinweise
- Es handelt sich hierbei lediglich um einen Kurzschlussschutz, der keine Überlastschutzfunktion bietet.
- Vor der Installation oder dem Austausch muss die Hauptstromversorgung getrennt werden, um die Gefahr eines versehentlichen Kurzschlusses zu vermeiden.
- Observe mounting torque 12.0 Nm ±1 Nm; loose contact will cause over‑heating under heavy‑current load.
- For enclosed high‑temperature compartments, temperature derating assessment shall be performed.
- Only replace with same‑specification protector to keep original circuit‑protection performance.
