2CCS802901R0639 ABB S802S-SCL100-SR 100 A 2-Pole Self-Resetting Short-Circuit Limiter

Why Choose the ABB S802S-SCL100-SR Self-Resetting Short-Circuit Limiter?

The ABB S802S-SCL100-SR is a high-performance self-resetting short-circuit current limiter designed for use with ABB S800 high-performance protection systems. Rated at 100 A with a 2-pole configuration, it provides additional short-circuit current limitation for demanding industrial and commercial electrical distribution applications.

As part of the ABB S800-SCL-SR range, the S802S-SCL100-SR is designed to limit high prospective short-circuit currents and thereby support downstream protective devices. Its self-resetting operating principle means the limiter can return to its normal conductive state following operation, helping minimise maintenance requirements compared with protection solutions that require replacement after every fault event.

ABB order code 2CCS802901R0639 identifies this IEC-version 100 A, 2-pole short-circuit limiter. The device is part of ABB's S800 modular protection platform and has a product weight of approximately 0.5 kg.

Reliable Short-Circuit Current Limiting for Electrical Distribution

Short-circuit current limiters are used to reduce the magnitude and duration of high fault currents reaching downstream electrical equipment. By limiting prospective short-circuit current, the ABB S802S-SCL100-SR can support effective protection coordination and reduce the electrical and thermal stresses imposed on downstream protective devices and installation components.

The S800-SCL-SR range uses a self-resetting design, allowing the limiter to return to its normal operating condition following fault operation when the appropriate system conditions are restored. ABB specifies that the combined rated currents of downstream motor starters or circuit breakers must not exceed the rated current of the S800-SCL-SR, making correct system coordination an important part of installation design.

Typical Applications

• Industrial electrical distribution systems.
• High prospective short-circuit current installations.
• Distribution boards and switchgear assemblies.
• Machine and production-line electrical systems.
• Motor control and protection installations.
• Commercial and industrial power distribution.
