ABB S203-C2 - 2A, 3-Pole, Miniature Circuit Breaker (MCB)

Meet the ABB S203-C2, a 2-amp, 3-pole miniature circuit breaker (MCB) engineered for dependable overcurrent protection in three-phase systems. Designed for panelboards, switchboards, and control panels, this device brings ABB’s precision engineering to industrial, commercial, and OEM environments where reliable electrical protection matters most.

The 3-pole configuration means you can guard all three conductors in a single, compact unit, streamlining installation and reducing panel footprint. The result is streamlined wiring, quicker commissioning, and simplified maintenance for three-phase equipment.

• Current rating: 2 A — precise protection tailored to small-to-moderate loads, minimizing nuisance trips while safeguarding conductors.
• Poles: 3-Pole — comprehensive three-phase protection ideal for motors, pumps, fans, and other 3-phase loads.
• Breaker type: Miniature Circuit Breaker (MCB) — reliable automatic disconnect on overloads or short circuits to prevent equipment damage.
• Applications: Suited for panelboards, switchboards, and control panels across industrial, commercial, and OEM settings, ensuring safe distribution and easy integration.

Key value: predictable, fast-acting protection that helps minimize downtime and extend the life of wiring and connected equipment. By safeguarding three-phase circuits in motor control centers and distribution panels, the S203-C2 helps keep critical processes online and reduces the risk of costly faults.

Who should consider this MCB? Engineers and technicians designing or upgrading electrical systems with three-phase loads, electricians servicing motor drives, and OEMs integrating compact, reliable protection into control assemblies. If you’re looking for a proven, single-device solution to reliably interrupt excessive current on all three lines, the ABB S203-C2 is built to deliver.

Installation and maintenance are straightforward: pair this 3-pole, 2 A breaker with compatible ABB equipment in suitable distribution panels, and verify conductor sizing and circuit protection are appropriate for your application. After any fault or trip, inspect the device and surrounding wiring, then replace as needed to maintain optimal protection.

Choose the ABB S203-C2 for consistent, three-phase protection that keeps your panel systems safe and your operations running smoothly.
