2CCS892001R0255 ABB S802N-B25 25 A 2-Pole Type B High Performance MCB 36 kA

Why Choose the ABB S802N-B25 High Performance MCB?

The ABB S802N-B25 is a high-performance 2-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical distribution and industrial control systems. As part of the ABB S800N high-performance circuit breaker series, it combines high fault-current interruption capability with a compact modular design for commercial and industrial applications.

This current-limiting circuit breaker features a Type B tripping characteristic and a rated current of 25 A. Its thermal tripping mechanism provides protection against sustained overloads, while the electromagnetic mechanism responds rapidly to short-circuit faults. The Type B characteristic is particularly suitable for circuits with relatively low starting or inrush currents.

With a breaking capacity of 36 kA, the S802N-B25 provides robust protection in installations where substantial prospective fault currents may occur. Its two-pole configuration enables simultaneous switching and protection across two conductors, while the S800N series' current-limiting design supports rapid and dependable fault interruption.

High-Performance Circuit Protection

The ABB S800N range is engineered for installations requiring compact circuit protection combined with high short-circuit interruption capability. Its thermal trip responds to sustained overload conditions, while the electromagnetic trip provides rapid interruption when severe short-circuit currents occur.

The S802N-B25 combines a 25 A current rating with a Type B trip curve and two-pole construction, making it suitable for distribution and equipment circuits where significant starting currents are not normally expected. Current-limiting operation helps reduce the energy passed through during a fault, supporting the protection of conductors and downstream electrical equipment.

Typical Applications

• Commercial electrical distribution systems.
• Industrial distribution and auxiliary circuits.
• Industrial control panels and switchboards.
• General-purpose circuits with relatively low inrush currents.
• Automation and production equipment.
• Circuits requiring high short-circuit interruption capability.
