2CCS803901R0539 ABB S803S-SCL32-SR 32 A 3-Pole Self-Resetting Short-Circuit Limiter

Why Choose the ABB S803S-SCL32-SR Self-Resetting Short-Circuit Limiter?

The ABB S803S-SCL32-SR is a high-performance self-resetting short-circuit current limiter designed for use in demanding industrial and commercial electrical protection systems. As part of the ABB S800-SCL-SR range, it provides additional short-circuit current limitation for downstream protective devices and equipment.

With a rated current of 32 A and a 3-pole configuration, the S803S-SCL32-SR is suitable for three-phase applications where high prospective fault currents require effective limitation. Its self-resetting design enables the limiter to return to its normal operating state after fault conditions have been cleared, helping reduce maintenance and component replacement requirements.

ABB order code 2CCS803901R0539 identifies this IEC-version short-circuit limiter. The S803S-SCL32-SR forms part of ABB's modular S800 protection platform and can be used in coordinated protection arrangements for motor starters, circuit breakers and industrial distribution systems with short-circuit levels up to 50 kA.

Reliable Short-Circuit Current Limiting for Industrial Protection

Short-circuit current limiters reduce the prospective fault current reaching downstream electrical equipment, helping protect circuit breakers, motor starters and associated installation components from severe electrical and thermal stresses. The ABB S803S-SCL32-SR is designed for coordinated protection arrangements where the available short-circuit current exceeds the capability that downstream devices can handle independently.

The S800-SCL-SR range combines high short-circuit limiting performance with a self-resetting operating principle. This makes the S803S-SCL32-SR particularly useful in industrial motor control and distribution systems where dependable protection, system availability and simplified maintenance are important design considerations.

Typical Applications

• Industrial three-phase electrical distribution systems.
• Motor starter backup protection.
• High prospective short-circuit current installations.
• Industrial control panels and switchgear assemblies.
• Machine and production-line electrical systems.
• Commercial and industrial power distribution.
