ABB S202M-C2UC 2-napainen johdonsuojakatkaisija C-käyrällä 2 A 10 kA 2CDS272061R0024

Where many miniature circuit breakers force a choice between compact footprint and robust protection, the ABB S202M-C2UC delivers both. This 2-pole MCB pairs a C tripping characteristic with a 10 kA breaking capacity, making it a dependable guard for circuits that see moderate inrush currents—think lighting arrays, control transformers, and small motors. Its dual compliance with IEC/EN 60898-1 and IEC/EN 60947-2 means it fits seamlessly into residential, commercial, and light industrial installations.

Highlights

• 2-pole configuration isolates both phase and neutral for complete circuit protection
• C tripping curve (5–10 times rated current) prevents nuisance tripping on normal inrush
• Rated current of 2 A suits sensitive loads and fine-wire circuits
• High breaking capacity of 10 kA at 230/400 V AC ensures safety under fault conditions
• Meets both IEC/EN 60898-1 and IEC/EN 60947-2 standards for broad application
• Operates reliably from -25°C to +55°C, covering demanding environments
• Energy limiting class 3 provides superior current limitation and downstream protection
• Tool-free DIN rail mounting for fast, secure installation

In daily use

Installed on a standard 35 mm DIN rail, the S202M-C2UC offers straightforward wiring with screw terminals that accept conductors up to 35 mm² rigid or 25 mm² flexible. The breaker’s mechanical and electrical endurance of 20,000 cycles translates to years of dependable service, while the IP20 protection (IP40 when enclosed) suits typical distribution boards. The C-curve allows momentary inrush currents without tripping, so your lighting or control circuits stay online when they should.
