AEG Elfaplus 6kA C-20A 3P Διακόπτης προστασίας γραμμής (2CDS253088R0204)

In commercial and industrial electrical distribution boards, the AEG Elfaplus 6kA C-20A 3P Miniature Circuit Breaker safeguards three-phase circuits against overload and short-circuit currents. Electricians and panel builders rely on its consistent tripping performance to protect cables and connected equipment in lighting, heating, and motor control applications.

Key specifications

• Rated current: 20 A
• Tripping characteristic: C
• Number of poles: 3
• Rated short-circuit breaking capacity: 6 kA at 230/400 V AC
• Rated voltage: 230/400 V AC, 50/60 Hz
• Mounting: DIN rail
• Terminal capacity: 0.75–35 mm² (rigid), 0.75–25 mm² (flexible)
• Standards: IEC/EN 60898-1, energy limiting class 3
• Module width: 3 modules (52.5 mm)

Why choose it

The C-curve ensures reliable protection for circuits with moderate inrush currents, such as lighting banks and small motors. Its 6 kA breaking capacity handles typical fault levels in sub-distribution boards, while the screw terminals accept a wide range of conductor sizes for flexible installation. The compact 3-module design saves space on the DIN rail without compromising performance.

Ideal use cases

• Protection of three-phase socket outlets and lighting circuits in commercial buildings
• Control circuits for HVAC equipment and pumps with moderate starting currents
• Feeder protection in industrial control panels and distribution boards
• Retrofit projects requiring a reliable, standards-compliant MCB

Good to know

The breaker is rated for ambient temperatures from -25 °C to +55 °C, with a storage range of -40 °C to +70 °C. It offers electrical endurance of 10,000 cycles and mechanical endurance of 20,000 cycles. Degree of protection is IP20 for terminals and IP40 when installed in an enclosure.
