Information About A4BY1200
The A4BY1200 is part of the Mersen / Ferraz Shawmut Class L fuse portfolio, developed for electrical systems that demand very high interrupting capability and dependable current limitation. It is designed to clear severe overcurrent and short-circuit conditions rapidly while reducing thermal and mechanical stress on connected equipment. The rejection-style construction helps prevent incorrect fuse installation, enhancing overall system safety. Its robust cylindrical fiber body and dual-element design ensure consistent performance in heavy-duty power distribution environments.
Key Features:
- Class L Current Limiting Design: Supports applications requiring extremely high interrupting capacity.
- 1200 Amp Rating: Suitable for main feeders and high-current distribution circuits.
- High Interrupting Capacity: Rated up to 200 kA AC for safe interruption of severe fault currents.
- Dual-Element Construction: Provides effective protection against both overloads and short-circuit events.
- Rejection-Type Configuration: Prevents improper fuse replacement and supports system integrity.
- Bolted Blade Terminals: Ensure secure electrical and mechanical connections in high-current installations.
- Industrial-Grade Materials: Fiber body construction supports durability in demanding operating conditions.
The A4BY1200 delivers the reliability and precision required for high-capacity overcurrent protection in Mersen / Ferraz Shawmut Class L industrial and commercial electrical systems.
