Interruptor automático magnetotérmico AEG Elfaplus 6kA B20A 1P (MCB) 2CDS251088R0205

The AEG Elfaplus 2CDS251088R0205 is a high-quality miniature circuit breaker (MCB) designed for reliable overcurrent protection in residential and commercial electrical installations. With a rated current of 20 A and B-curve tripping characteristic, it ensures fast disconnection in case of short circuits while allowing normal inrush currents. This 1-pole MCB has a breaking capacity of 6 kA and complies with IEC/EN 60898-1 standards.

Advantages

Compact 1-pole design saves space on DIN rail; B-curve characteristic ideal for resistive and lighting loads; high breaking capacity of 6 kA ensures safety; screw terminals for secure wiring up to 35 mm² rigid; energy limiting class 3 reduces let-through energy.

Suitable for

• Overcurrent protection of lighting circuits
• Protection of socket outlets and small appliances
• Residential and commercial distribution boards
• DIN rail mounting in electrical cabinets
