2CCF019945R0001 ABB S802S-K0.5 0.5A 2-Pole Type K 50kA High Performance MCB

Why Choose the ABB S802S-K0.5 High Performance MCB?

The ABB S802S-K0.5 is a high-performance 2-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical systems. As part of the ABB S800S high-performance circuit breaker series, it combines current-limiting performance, compact modular construction and high breaking capacity for commercial and industrial applications.

This circuit breaker uses thermal protection against sustained overloads together with electromagnetic protection against short-circuit faults. Its Type K tripping characteristic is suited to circuits with elevated starting or inrush currents, making it useful for appropriate motor, transformer, control and other inductive-load applications while helping to reduce unwanted tripping during normal equipment start-up.

With a rated current of 0.5 A, a 2-pole configuration and a maximum short-circuit breaking capacity of 50 kA, the S802S-K0.5 provides robust protection for low-current circuits where high prospective fault currents may be present. Its two-pole design enables simultaneous protection and disconnection of two conductors, making it suitable for professional electrical distribution, machinery and control applications.

High-Performance Two-Pole Circuit Protection for Industrial Systems

High-performance miniature circuit breakers such as the ABB S802S-K0.5 automatically disconnect protected circuits when excessive current results from an overload or short circuit. Thermal tripping responds to sustained overcurrent conditions, while electromagnetic tripping provides rapid operation during high-current short-circuit faults. The two-pole configuration allows both protected conductors to be disconnected together.

The ABB S800S range is designed for installations requiring higher breaking performance than conventional miniature circuit breakers. The Type K characteristic of the S802S-K0.5 makes it particularly suitable for appropriate inductive loads and circuits subject to elevated short-duration starting currents, while current-limiting operation helps reduce fault energy and protect downstream electrical equipment.

Typical Applications

• Industrial machinery and automation systems.
• Control and auxiliary circuits.
• Low-current industrial equipment.
• Two-pole electrical distribution circuits.
• Electrical distribution boards and switchgear.
• Inductive loads with elevated starting currents.
• Motor and transformer circuits where a Type K characteristic is appropriate.
• Applications requiring high short-circuit breaking capacity.
