2CCS894001R0065 ABB S804N-B6 MCB 36kA 4P Type B 6A

Why Choose the ABB S804N-B6 High Performance MCB?

The ABB S804N-B6 is a high-performance 4-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in demanding commercial and industrial installations. As part of the ABB S800N high-performance MCB range, it combines four-pole protection with high short-circuit breaking capacity and a robust DIN rail format.

Featuring a 6 A rated current and Type B tripping characteristic, the S804N-B6 is suitable for circuits requiring relatively sensitive instantaneous short-circuit protection. Its thermal and electromagnetic operating principles provide dependable overload and short-circuit protection, while its current-limiting design helps reduce the energy released during high-current faults.

The S804N-B6 provides a rated ultimate short-circuit breaking capacity of 36 kA at 415 V AC and a rated service short-circuit breaking capacity of 30 kA at 415 V AC according to IEC/EN 60947-2. With four protected poles, a 690 V rated insulation voltage and robust screw terminals, it is well suited to industrial distribution boards, machinery and other four-pole electrical systems requiring high-performance circuit protection.

High-Performance Four-Pole Circuit Protection

Miniature circuit breakers such as the ABB S804N-B6 automatically interrupt electrical circuits when excessive current occurs because of an overload or short circuit. Thermal protection responds to sustained overload conditions, while electromagnetic protection provides rapid interruption during high-current short-circuit faults, helping protect conductors, connected equipment and the wider electrical installation.

The ABB S800N range is engineered for installations requiring substantially higher breaking capacities than conventional miniature circuit breakers. Combining a 6 A rating, Type B characteristic and four protected poles, the S804N-B6 provides dependable protection for commercial and industrial electrical systems where high prospective short-circuit currents may be present.
