Sygonix SY-6440994 interruttore automatico magnetotermico 3 poli B16 16A 6kA 415V AC

The Sygonix SY-6440994 is a 3-pole miniature circuit breaker (MCB) with a B16 tripping characteristic, rated for 16 A and 415 V AC. Its 6 kA breaking capacity and thermal-magnetic trip mechanism provide reliable protection against overcurrent and short circuits in industrial and commercial electrical installations. The compact 3-module design mounts directly onto a standard DIN rail, simplifying integration into distribution boards.

Highlights

• 3-pole MCB with B tripping characteristic
• Rated current: 16 A
• Rated voltage: 415 V AC
• Breaking capacity: 6 kA
