Why Choose the ABB S803U-Z15 High Performance MCB?
The ABB S803U-Z15 is a high-performance three-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding industrial and commercial electrical systems. Part of the ABB S800U high-performance circuit breaker range, this model combines a 15 A rated current, Z tripping characteristic and high 50 kA short-circuit breaking capacity with UL 489 compliance.
The S803U-Z15 uses thermal and electromagnetic tripping mechanisms to protect conductors and connected equipment against sustained overloads and short-circuit faults. Its Z characteristic provides sensitive instantaneous magnetic operation, making it particularly suitable for circuits containing electronic equipment, control systems and other loads with relatively low normal inrush currents.
With three protected poles and a specified 50 kA short-circuit breaking capacity, the S803U-Z15 provides robust protection where high prospective fault currents may occur. Its UL 489 classification supports use in applications requiring branch-circuit protection, while the ABB order code for this exact breaker is 2CCS863017R0155.

Reliable Protection for Sensitive Electrical Circuits
The ABB S803U-Z15 combines thermal overload protection with sensitive electromagnetic short-circuit protection. The thermal element responds to sustained overcurrent conditions, while the magnetic mechanism provides rapid interruption when fault current reaches the Z-characteristic instantaneous trip range, helping reduce electrical stress on conductors and connected equipment.
The Z characteristic is particularly useful where electronic, control or other sensitive loads require rapid magnetic fault response and do not normally produce substantial starting-current peaks. Combined with the high breaking capacity and UL 489 design of the S800U platform, the S803U-Z15 provides dependable protection for demanding industrial and commercial installations.
Typical Applications
- Industrial control and automation circuits.
- Sensitive electronic equipment protection.
- Three-phase control and distribution circuits.
- Industrial control panels and switchboards.
- Commercial electrical distribution systems.
- UL 489 branch-circuit protection applications.
