EATON PXL-C40/3 Miniature Circuit Breaker (MCB), 3-Pole, 40 A, C-Curve, 10 kA, 230/400 V AC

This 3-pole miniature circuit breaker from Eaton's PXL series delivers dependable protection for electrical circuits up to 40 A. With a C tripping characteristic, it responds to overloads and short circuits while allowing moderate inrush currents, making it ideal for commercial and industrial distribution boards. The breaker's 10 kA breaking capacity and compliance with IEC/EN 60898-1 ensure safe interruption of fault currents, protecting both wiring and connected equipment.

Advantages

The PXL-C40/3 combines robust construction with user-friendly features. Screw terminals accept solid conductors up to 25 mm² and flexible conductors up to 16 mm², providing secure, low-maintenance connections. A clear red/green contact position indicator lets you verify the switching state at a glance. The breaker mounts quickly on standard 35 mm DIN rails and supports pin-type busbar connections for streamlined panel assembly. With an electrical endurance of over 10,000 operating cycles and mechanical endurance of over 20,000 cycles, it offers long-term reliability in demanding environments.
