FS2-B0-11-820-12A-BG Description

Short technical summary and product information.

The Littelfuse FS2-B0-11-820-12A-BG is a 2-pole magnetic (hydraulic delay) circuit breaker rated for 200A at 277V. It is designed for chassis mount installation and features a lever actuator for manual operation. The breaker is approved by CCC, cULus, and UL489, confirming its suitability for use in various applications requiring reliable circuit protection.

 

The magnetic hydraulic delay trip mechanism provides precise overcurrent protection while accommodating transient inrush currents. This device is suitable for use in power distribution panels, industrial machinery, and commercial equipment where high current capacity and robust protection are needed. The chassis mount design allows for secure installation in enclosures, and the lever actuator provides clear visual indication of the breaker status.

 

The 2-pole configuration can protect two separate circuits or a single 240V circuit. The 200A rating makes it ideal for main breaker or feeder protection applications. The breaker is non-illuminated, maintaining simplicity and reliability.
