The ABB S201-Z1A is a single-pole miniature circuit breaker (MCB) with a Z-curve tripping characteristic, designed for sensitive equipment protection in low-voltage distribution systems. With an ICU rating of 10kA and compliance with IEC 60947-2, this German-manufactured device is widely used in marine electrical panels, navigation equipment circuits, and control system distribution boards where precise overcurrent protection is critical. Its Z-curve characteristic provides fast tripping at low multiples of rated current, making it ideal for protecting electronic instrumentation and sensitive shipboard loads.
Key Features
✓ Z-curve tripping characteristic for sensitive load protection with LI = 2.5 x IN instantaneous release

✓ Rated for UMAX 253/440 VAC with 4kV impulse withstand voltage (UIMP)
✓ Single-pole (1P) compact design suitable for DIN rail mounting in marine switchboards
✓ Manufactured in Germany by ABB to rigorous industrial and marine quality standards
Marine Applications
Protection of sensitive navigation and bridge electronics circuits
Control panel and automation system feeder protection in engine rooms
Instrumentation circuit breakers in power management and monitoring systems
Auxiliary circuit protection in marine low-voltage distribution boards
Dedicated branch circuit protection for communication and safety systems onboard
Why Marine Engineers Choose
Marine engineers rely on the ABB S201 Z-curve series for its precise and rapid overcurrent protection of sensitive electronic equipment. The Z-curve characteristic trips faster than standard B or C curves at lower fault currents, safeguarding delicate instrumentation and control circuits commonly found throughout vessel electrical systems. ABB’s proven reliability and IEC compliance make it a trusted choice for critical marine installations.
Ideal For
Commercial vessels, offshore platforms, cargo ships, tankers, passenger vessels, naval ships, research vessels, and any marine or industrial application requiring precise overcurrent protection for sensitive electronic circuits and instrumentation.
Technical Support & Compliance
We provide complete solutions including remote troubleshooting, onboard support, testing and commissioning, repair, retrofit and upgrade services, and full integration support for marine electrical distribution systems. To confirm compatibility with your specific installation, please share nameplate photos, part numbers, electrical drawings, system model and version details, vessel name and IMO number, and project scope. All technical recommendations are subject to confirmation based on your vessel’s specific configuration and classification requirements.
