EATON PXF-40/4/003-A aardlekschakelaar 40A 4-polig 30mA type A

Residual current circuit breaker (RCCB) with 40 A rated current, 4-pole, 30 mA sensitivity, Type A tripping characteristic, and 10 kA conditional short-circuit rating. It instantly disconnects the circuit upon detecting hazardous residual currents, protecting people and equipment from earth fault currents. Type A detection covers alternating and pulsating direct residual currents, making it ideal for installations with electronic components.

Advantages

Robust protection with a conditional short-circuit rating of 10 kA ensures safety even under fault conditions. The compact 4-module (70 mm) design saves space on the DIN rail. IP20 terminals and IP40 front provide reliable insulation. Mechanical endurance of 20,000 operations and electrical endurance of 10,000 operations deliver long-term dependability. Wide terminal capacity from 1.5 to 35 mm² accommodates various conductor sizes, simplifying installation.

Suitable for

• Residential distribution boards requiring earth leakage protection
• Commercial buildings with mixed loads including electronic equipment
• Industrial control panels needing Type A RCD protection
• Installations where pulsating DC residual currents may occur
