~400V
COMPACT HOME SH200 MINIATURE CIRCUIT BREAKERS ARE CURRENT LIMITING. THEY HAVE TWO DIFFERENT TRIPPING MECHANISMS, THE DELAYED THERMAL TRIPPING MECHANISM FOR OVERLOAD PROTECTION AND THE ELECTROMECHANIC TRIPPING MECHANISM FOR SHORT CIRCUIT PROTECTION. THEY ARE AVAILABLE IN DIFFERENT CHARACTERISTICS
MADE IN GERMANY
REF: FKM5852
The ABB SH202 B6 is a two-pole miniature circuit breaker (MCB) rated for ~400V operation with a B-curve tripping characteristic and 6A rated current. Designed for current-limiting protection, this MCB integrates both delayed thermal tripping for overload protection and an electromagnetic tripping mechanism for short-circuit protection. Onboard vessels, MCBs of this type are essential for safeguarding low-voltage distribution panels, lighting circuits, control circuits, and auxiliary equipment against overcurrent faults. Reliable circuit protection is critical in the marine environment where electrical system integrity directly impacts vessel safety and operational continuity.
Key Features
✓ Two-pole (2P) miniature circuit breaker with B-curve tripping characteristic for general-purpose protection
