Why choose it

The PXL range from EATON is known for its precision and durability. With a high short-circuit breaking capacity of 10 kA, this MCB protects wiring and equipment from overloads and short circuits. The C-curve trips between 5 and 10 times the rated current, so it is suitable for circuits with inrush currents, such as motors and transformers. The compact design fits easily on standard DIN rails, and the screw terminals ensure secure, maintenance-free connections.

Ideal use cases

• Three-phase distribution boards
• Lighting circuits with high inrush current
• Socket outlet circuits in commercial buildings
• Small motor and transformer protection

Good to know

The MCB is rated for use in 400 V AC systems and features an impulse withstand voltage of 4 kV, making it suitable for Category III overvoltage environments. It operates reliably across a wide temperature range and is designed for long service life, with mechanical endurance exceeding 20,000 operations. No separate accessory is required for mounting on Th35 DIN rails.
