Circuit breaker E.NEXT e.mcb.pro.60 1P B20A 6kA (EX-P041009)

Single-pole miniature circuit breaker E.NEXT e.mcb.pro.60 with B20 trip characteristic and 6 kA short-circuit breaking capacity is designed to protect branch circuits in residential and light commercial electrical installations. It provides combined thermal-magnetic protection against overload and short-circuit conditions, fits standard DIN-rail enclosures and uses conventional screw-type terminals for secure conductor connection. The device is compact, intended for single-phase circuits, and complies with typical requirements for domestic circuit protection.

Advantages

The breaker offers reliable thermal-magnetic tripping with a B20 characteristic that enables discrimination between temporary inrush currents and harmful overloads. Its 6 kA breaking capacity ensures safe interruption of fault currents typical in small installations. Standardized DIN-rail mounting and accessible screw terminals simplify installation and maintenance. The single-pole format saves space in distribution boards while providing clear isolation of the protected circuit.

Suitable for

• Protection of lighting and socket circuits in apartments and houses
• Branch circuit protection in small offices and light-commercial premises
• Use in single-phase distribution boards and consumer units
• Retrofit projects where space and standard connections are required

Key specifications

• Poles: single-pole (1P)
• Tripping characteristic: B curve, 20 A rated current
• Short-circuit breaking capacity: 6 kA
• Protection type: thermal-magnetic (overload and short-circuit)
• Mounting: DIN-rail (standard 35 mm)
• Terminals: screw-type for solid and stranded conductors
• Application: single-phase AC circuits

How to use

Install the circuit breaker on a standard 35 mm DIN rail inside a distribution board. Ensure the supply is isolated before wiring. Connect the phase conductor to the breaker’s line terminal and the load conductor to the load terminal, tightening terminals to the manufacturer’s recommended torque. After wiring, restore supply and verify proper operation by switching the breaker on and off. Use the breaker as part of a coordinated protection scheme together with residual current devices or upstream protection where required.

Usage recommendations

Verify compatibility with the installation’s nominal voltage and upstream protective devices. Use appropriate conductor cross-sections and torque settings to ensure reliable connections. Periodically inspect terminals and mounting for signs of overheating or loosening; replace the device if it shows mechanical damage or fails to trip correctly.
