Why Choose the ABB S303P-C3 Miniature Circuit Breaker?
The ABB S303P-C3 (Product ID: 2CDS383001R0034) is a high-performance 3-pole miniature circuit breaker (MCB) designed to protect industrial electrical installations against overloads and short circuits. Part of ABB's trusted System pro M compact S300P series, it is manufactured in accordance with international IEC and UL standards for dependable use in demanding control, distribution and machinery applications.
Engineered for reliable long-term operation, the S303P-C3 combines thermal overload protection with rapid electromagnetic short-circuit protection. Its compact modular housing is designed for straightforward DIN rail installation, while the patented terminal arrangement helps support secure cable and busbar connections.
Featuring a 3 A rated current, three protected poles and a C tripping characteristic, this MCB is particularly suitable for three-phase circuits with moderate starting currents. Its high short-circuit interruption capability helps improve installation safety and service continuity in industrial environments.
Key Advantages
- Dependable overload and short-circuit protection.
- 3 A rated current for lower-current industrial circuits.
- 3-pole configuration for simultaneous three-phase protection.
- C tripping characteristic suitable for moderate inrush currents.
- High breaking capacity for demanding industrial installations.
- Compact modular construction for efficient panel integration.
- Compatible with ABB System pro M compact accessories.
Key Features
- ABB System pro M compact S300P series.
- 3 A nominal current.
- Three protected poles.
- Type C tripping curve.
- Rated operational voltage of up to 415 V AC.
- Suitable for selected DC applications up to 125 V DC.
- High short-circuit breaking performance.
- Integrated trip indication for easier fault identification.
- Dual DIN rail release for efficient installation and removal.
- Supply connection possible from the top or bottom.
Reliable Three-Phase Circuit Protection
The ABB S303P-C3 uses two complementary tripping mechanisms to protect connected wiring and equipment. A delayed thermal release responds to sustained overload conditions, while an electromagnetic release rapidly disconnects the circuit when a short circuit occurs.
Its C tripping characteristic is commonly used for circuits containing equipment with moderate switch-on currents. This makes the device suitable for industrial controls, small transformers, solenoid-operated equipment, lighting circuits and other general-purpose three-phase loads.
Typical Applications
- Industrial control panels.
- Three-phase auxiliary circuits.
- Automation and process-control equipment.
- Machine building and OEM assemblies.
- Commercial and industrial distribution boards.
- Small transformers and power supplies.
- Lighting and general-purpose load circuits.
- Transportation and renewable-energy equipment.
