Sygonix SY-6440986 Miniature Circuit Breaker 1P C25 6kA 25A 240V AC DIN Rail

The Sygonix SY-6440986 is a 1-pole miniature circuit breaker (MCB) with a C-curve tripping characteristic, rated for 25 A and 240 V AC. It offers a 6 kA short-circuit breaking capacity and mounts on a standard DIN rail, making it a reliable choice for protecting circuits in residential and commercial installations.

Highlights

• 1-pole MCB with C-curve for general circuit protection
• Rated current 25 A, voltage 240 V AC
• 6 kA breaking capacity (Icn) per IEC/EN 60898-1
• DIN rail mounting (EN 60715)
• Screw terminals accept 1–25 mm² conductors

In daily use

This MCB trips magnetically on high inrush currents (5–10 times rated current) and thermally on sustained overloads, protecting wiring and equipment. Its compact design fits standard distribution boards, and the screw terminals ensure secure connections for both solid and stranded conductors.
