AMWEI Ordering Code: AMZ11-05P601N420
- Application: Overcurrent protection, Overload, Short circuit protection.
- Best suited to meet the requirements for measuring instrumentation and meter circuit overload and short circuit protection, power supplies motor transformer protection.
- Error-free operations are assured by rush current.
- Circuit is protected until current is turned off.
- Restores the original low resistance value automatically once the overload is removed.
- Non-contact design leads to long life and no noise.
- Durable and strong against mechanical vibration and shock.
