Eaton PXF-63/4/03-A Interruttore differenziale (RCCB), 63 A, 4 poli, 300 mA, tipo A 236804

Eaton PXF-63/4/03-A is a 4-pole residual current circuit breaker (RCCB) rated for 63 A and 300 mA residual current, providing reliable protection against earth leakage faults in industrial and commercial installations. Its Type A tripping characteristic ensures sensitivity to alternating and pulsating direct residual currents.

Overview

The PXF series RCCB is designed for DIN rail mounting and features a compact 4-module width (70 mm). It operates at 230/400 V AC and 50/60 Hz, with a conditional short-circuit current of 10 kA when protected by an upstream 63 A gG/gL fuse. The device has a trip position indicator for quick status identification.

What stands out

• Rated residual current of 300 mA for reliable fault detection
• Type A tripping suitable for AC and pulsating DC residual currents
• Wide terminal capacity from 1.5 to 35 mm² for flexible wiring
• High electrical endurance: over 4,000 operations
• Operating temperature range from -25 °C to +40 °C
