Eaton PXL-C4/1 disjuntor automático (MCB), 1 polo, C4, 4 A, 230/400 V AC, 10 kA, calha DIN 236051

Electricians and panel builders use the Eaton PXL-C4/1 to protect lighting and control circuits in residential and commercial distribution boards. This 1-pole miniature circuit breaker (MCB) with C-curve trips at 5–10 times rated current, handling inrush from small motors and transformers while still protecting cables from overload and short circuit.

Key specifications

• Rated current: 4 A
• Tripping characteristic: C
• Number of poles: 1
• Rated voltage: 230/400 V AC
• Rated switching capacity: 10 kA according to EN 60898-1
• Frequency: 50/60 Hz
• Mounting: DIN rail
• Module width: 1 TE (17.5 mm)
• Terminal capacity: 1–25 mm²
• Degree of protection: IP20 (terminals), IP40 (housing with cover)

Why choose it

The PXL-C4/1 combines a compact 1-module design with a 10 kA breaking capacity, making it suitable for use in main distribution boards where higher fault currents can occur. Screw terminals accept a wide range of conductor sizes, and the C-curve provides reliable protection for circuits with moderate inrush currents.

Ideal use cases

• Protection of lighting circuits in residential and commercial buildings
• Control circuits for small motors, solenoids, and transformers
• Distribution boards requiring DIN rail mounting and 1-pole protection

Good to know

The breaker complies with EN 60898-1 and IEC 60898-1, ensuring performance and safety for household and similar installations. It operates in ambient temperatures from -25 °C to +75 °C, with an energy limiting class of 3 for effective short-circuit protection.
