2CCS801901R0599 ABB S801S-SCL63-SR MCB 50kA 1P 63A Short-Circuit Limiting

Why Choose the ABB S801S-SCL63-SR MCB?

The ABB S801S-SCL63-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 63 A rated current with high short-circuit performance for installations where robust protection is required.

This model is specified as an SC Lim. short-circuit limiting circuit breaker. Current-limiting operation helps restrict the magnitude and energy of a short-circuit fault by interrupting the fault rapidly, reducing the electrical and thermal stresses passed downstream compared with an unrestricted fault condition.

With a high 50 kA short-circuit breaking capacity and a compact 1-pole configuration, the S801S-SCL63-SR provides dependable protection for demanding branch and distribution circuits. ABB order code 2CCS801901R0599 uniquely identifies this 63 A short-circuit limiting model.

Reliable Short-Circuit Current-Limiting Protection

During a short circuit, extremely high current can develop rapidly and impose severe thermal and electrodynamic stresses on conductors, equipment and other components within the electrical system. A current-limiting circuit breaker interrupts the fault quickly, limiting the peak current and fault energy that can pass through the protected circuit.

The ABB S801S-SCL63-SR combines this short-circuit limiting function with a 63 A current rating and 50 kA breaking capacity. This makes it suitable for demanding electrical installations where high prospective fault currents 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.
• Branch circuits requiring 63 A protection.
• Applications requiring short-circuit current limitation.
