Circuit Breaker E.NEXT e.mcb.pro.60 3-pole B20A 6kA (EX-P041027)

The E.NEXT e.mcb.pro.60 three-pole miniature circuit breaker with B20A tripping characteristic and 6 kA breaking capacity is designed for overcurrent and short-circuit protection in three-phase electrical installations. This compact DIN-rail mounted device fits standard distribution boards and provides coordinated protection for motor circuits, distribution feeders and branch circuits where a B curve response is required. The breaker’s construction enables straightforward mounting, manual switching and clear indication of contact position.

Advantages

The device offers a balance of sensitivity and selectivity through its B20A tripping curve, providing reliable protection against overloads while allowing temporary inrush currents typical of lighting and small motor loads. With a rated breaking capacity of 6 kA it meets common requirements for residential, commercial and light industrial panels. Its compact three-pole design reduces panel space usage and supports consistent switching across all phases.

Suitable for

• Protection of three-phase branch circuits in homes and apartments
• Feeder protection in commercial lighting and small HVAC systems
• Distribution boards in light industrial or workshop environments
• Motor protection where moderate inrush currents are expected

Key specifications

• Number of poles: 3-pole
• Tripping characteristic: B curve (suitable for resistive and small inductive loads)
• Rated current: 20 A
• Breaking capacity: 6 kA
• Mounting: DIN-rail
• Operation: manual toggle with clear contact position indication

How to use

Install the three-pole breaker on a standard DIN-rail inside the distribution board, ensuring correct phase sequence and secure terminal connections. Tighten terminals to the manufacturer’s recommended torque and verify that the incoming and outgoing conductors are rated correctly for 20 A. After wiring, switch the breaker on to confirm correct operation and test the protected circuit under load conditions appropriate for commissioning. Follow local electrical codes and safety procedures during installation and maintenance.

Usage recommendations

Use the breaker as part of a coordinated protection scheme: pair it with appropriate upstream and downstream devices and include residual-current protection where required. Periodically inspect terminals for tightness and signs of overheating, and replace the device if mechanical damage or repeated tripping indicates degradation.
