Sygonix SY-6438020 interruttore differenziale tipo A 4 poli 63 A 30 mA 400 V AC

Rated at 63 A with 30 mA residual current sensitivity, this 4-pole Type A RCCB protects against AC and pulsating DC earth faults in 400 V AC installations.

Overview

The Sygonix SY-6438020 is a residual current circuit breaker (RCCB) for DIN rail mounting. It monitors residual currents and disconnects the circuit when a fault current of 30 mA or higher is detected, protecting people and equipment from dangerous leakage currents.

What stands out

• Type A tripping: detects AC and pulsating DC residual currents.
• 4-pole design for three-phase systems with neutral.
• 63 A rated current for demanding circuits.
• 30 mA sensitivity for personal protection.
• 10 kA short-circuit withstand capability.

Technical details

• Rated voltage: 400 V AC
• Frequency: 50/60 Hz
• Mounting: DIN rail
• Connection: screw terminals
• Degree of protection: IP20
• Operating temperature: -25 to +40 °C
