Eaton PXL-C20/3 Miniature Circuit Breaker (MCB) 3-Pole 20 A C-Curve 10 kA

Electrical faults and overloads can cause serious damage to wiring and equipment, leading to costly downtime and safety hazards. The Eaton PXL-C20/3 Miniature Circuit Breaker (MCB) provides reliable protection for three-phase circuits against overload and short-circuit currents, ensuring continuous operation and safety in residential, commercial, and industrial installations.

Who is it for

This MCB is ideal for electricians, panel builders, and facility managers who need a dependable, compact protection device for three-phase distribution boards. It suits applications with moderate inrush currents, such as lighting circuits, socket outlets, and small motors, where a C-curve tripping characteristic is required.

Main features

• 3-pole design for three-phase circuits, rated at 20 A with C tripping characteristic.
• High breaking capacity of 10 kA according to EN 60898-1, providing robust short-circuit protection.
• DIN rail mounting (EN 60715) for quick and secure installation in standard distribution boards.
• Compact width of only 3 modules (52.5 mm), saving space in enclosures.
• Energy limiting class 3 ensures excellent current limitation, reducing thermal and mechanical stress on downstream components.
• Screw terminals accept solid, stranded, and flexible conductors up to 25 mm² (solid/stranded) or 16 mm² (flexible), ensuring versatile wiring options.
• Wide operating temperature range from -25 °C to +50 °C for reliable performance in harsh environments.
• Complies with EN 60898-1 and IEC 60898-1 standards, guaranteeing safety and quality.

Tips

When selecting an MCB, ensure the tripping curve matches the load type: C-curve is suitable for general lighting and socket circuits with moderate inrush currents. Always verify the short-circuit current at the installation point does not exceed the breaker's breaking capacity. For enhanced protection, consider adding a residual current device (RCD) upstream.
