Why Choose the ABB S802S-SCL63-SR Self-Resetting Short-Circuit Limiter?
The ABB S802S-SCL63-SR is a high-performance two-pole, 63 A self-resetting short-circuit limiter designed to provide back-up protection for compatible downstream electrical protection devices. Part of the ABB S800-SCL-SR range, it is engineered for installations where high prospective short-circuit currents require effective current limitation while maintaining maximum system availability.
The S802S-SCL63-SR has a 63 A rated continuous current and is designed as an IEC-version short-circuit limiter for coordinated protection within ABB electrical distribution systems. During a downstream short circuit, the device rapidly limits the fault current, reducing the electrical and thermal stress imposed on compatible downstream circuit breakers and connected equipment.
A key feature of the S800-SCL-SR technology is its automatic self-resetting operation. Once the downstream protective device has interrupted the faulty branch, the limiter automatically returns to its normal operating condition, allowing unaffected parallel circuits to remain energised and supporting continuity of service in demanding industrial installations.
Key Advantages
- Self-resetting short-circuit limiter for professional electrical distribution systems.
- 63 A rated continuous current for higher-current applications.
- Two-pole configuration for coordinated two-pole circuit protection.
- Designed for installations with high prospective short-circuit currents.
- Limits fault-current energy reaching compatible downstream protective devices.
- Automatically resets after the downstream protective device clears the fault.
- Supports coordinated back-up and group protection.
- Helps unaffected parallel circuits remain operational when another branch experiences a fault.

Self-Resetting Short-Circuit Limitation for Improved System Availability
Electrical installations with high prospective fault currents can require additional current-limiting protection ahead of downstream protective devices. The ABB S802S-SCL63-SR is designed to restrict the magnitude and energy of a short-circuit current, helping compatible downstream devices interrupt faults safely while reducing stress on the electrical installation.
Unlike a conventional upstream protective device that can leave an entire group of circuits disconnected after operation, the S800-SCL-SR concept automatically resets after the downstream device clears the affected fault. This allows only the faulty branch to remain isolated while healthy parallel circuits continue operating, making the technology particularly useful where continuity of supply is important.
Typical Applications
- Group protection of multiple downstream electrical circuits.
- Back-up protection for compatible ABB high-performance circuit breakers.
- Industrial power distribution systems.
- Motor control and machinery installations.
- Electrical systems with high prospective short-circuit currents.
- Industrial switchgear and distribution panels.
- Applications requiring improved selectivity and continuity of supply.

Frequently Asked Questions
What is the ABB S802S-SCL63-SR used for?
The ABB S802S-SCL63-SR is a self-resetting short-circuit limiter designed to limit high fault currents and provide coordinated back-up or group protection for compatible downstream electrical protection devices.
What is the rated current of the S802S-SCL63-SR?
The S802S-SCL63-SR has a rated continuous current of 63 A and is configured as a two-pole device.
Is the ABB S802S-SCL63-SR a conventional MCB?
No. Although it forms part of ABB's S800 circuit protection portfolio, the S802S-SCL63-SR is specifically a self-resetting short-circuit limiter intended to provide current limitation and coordinated back-up protection for compatible downstream devices.
What does self-resetting mean on the S802S-SCL63-SR?
During a downstream short circuit, the limiter acts to restrict the fault current while the downstream protective device interrupts the affected circuit. After fault clearance, the S802S-SCL63-SR automatically returns to its normal operating condition, helping healthy parallel circuits remain in service.
Where is the ABB S802S-SCL63-SR typically installed?
The S802S-SCL63-SR is typically used in industrial distribution boards, switchgear and group-protection systems where high prospective short-circuit currents require current limitation and continuity of supply is important.
Trusted Short-Circuit Protection from ABB
ABB S800-SCL-SR self-resetting short-circuit limiters provide effective current limitation and coordinated back-up protection while supporting continuity of supply, allowing faulty downstream branches to be isolated without unnecessarily interrupting healthy parallel circuits.
