2CCS801901R0639 ABB S801S-SCL100-SR MCB 50kA 1P 100A Short-Circuit Limiting

Why Choose the ABB S801S-SCL100-SR MCB?

The ABB S801S-SCL100-SR is a high-performance single-pole miniature circuit breaker (MCB) designed for demanding industrial and commercial electrical distribution applications. Part of the ABB S800 high-performance circuit breaker range, it combines a substantial 100 A rated current with high short-circuit capability for circuits where robust fault protection is required.

This model is specified as an SC Lim. short-circuit limiting circuit breaker. Its current-limiting function is designed to interrupt severe short-circuit currents rapidly, restricting the peak current and fault energy passed through the circuit and thereby helping reduce thermal and electrodynamic stresses on conductors and downstream equipment.

With a high 50 kA short-circuit breaking capacity and a compact 1-pole configuration, the S801S-SCL100-SR provides dependable high-current circuit protection for demanding electrical installations. ABB order code 2CCS801901R0639 uniquely identifies this 100 A short-circuit limiting model.

Reliable Short-Circuit Current-Limiting Protection

A severe short circuit can produce extremely high current within a very short period, subjecting cables, busbars and connected equipment to substantial thermal and electrodynamic forces. A short-circuit limiting breaker acts rapidly to interrupt the fault and restrict the peak current and energy that pass through the protected circuit.

The ABB S801S-SCL100-SR combines this short-circuit limiting function with a 100 A current rating and 50 kA breaking capacity. This combination makes it suitable for demanding electrical systems where high prospective fault levels require robust interruption and effective limitation of short-circuit stresses.

Typical Applications

• Industrial electrical distribution systems.
• Commercial power distribution installations.
• Industrial control panels and switchboards.
• Machine and equipment supply circuits.
• High-fault-level electrical installations.
• High-current circuits requiring 100 A protection.
• Applications requiring short-circuit current limitation.
