Circuit breaker E.NEXT e.mcb.pro.60 1P C20A 6 kA (MPN EX-P042009)

Single-pole miniature circuit breaker E.NEXT e.mcb.pro.60 with C20A tripping characteristic and 6 kA breaking capacity is designed for overcurrent protection in residential and light commercial electrical circuits. The device provides combined thermal-magnetic protection, reacting to sustained overloads with its thermal element and to short-circuits with its magnetic trip. Its compact form factor and DIN-rail mounting make it suitable for standard distribution boards and panel installations, while conventional screw terminals allow straightforward connection of phase conductors.

Advantages

The E.NEXT e.mcb.pro.60 C20A delivers consistent thermal-magnetic switching behavior with a defined C characteristic, ensuring selectivity with downstream protective devices under normal operating conditions. With a rated breaking capacity of 6 kA it meets common requirements for protection against short-circuits in domestic and small commercial installations. The single-pole design minimises space consumption in the distribution board and supports routine maintenance and replacement due to its standard mounting and terminal arrangement.

Suitable for

• Overcurrent protection of single-phase circuits in homes and apartments
• Protection of lighting and socket circuits in small offices and retail spaces
• Use as a branch circuit breaker in distribution boards and consumer units
• Retrofit and new-install electrical panels with DIN-rail arrangements

Key specifications

• Poles: single-pole (1P)
• Tripping characteristic: type C (C curve)
• Rated current: 20 A
• Breaking capacity: 6 kA
• Trip mechanism: thermal-magnetic
• Mounting: DIN-rail (standard rail mounting)
• Connection: standard screw terminals for phase conductor

How to use

Install the circuit breaker on a standard 35 mm DIN-rail inside the distribution board, ensuring the device is positioned according to the panel layout and local wiring regulations. Connect the phase conductor to the line terminal and the outgoing load conductor to the load terminal, and tighten terminals to the recommended torque values specified in the installation manual. Verify correct polarity and that the neutral and protective earth conductors are routed separately as required. After wiring, switch the breaker to the ON position and perform appropriate insulation and functional checks before energising downstream circuits.

Usage recommendations

Use the E.NEXT e.mcb.pro.60 C20A in single-phase branch circuits with expected inrush currents within the C characteristic range; coordinate the device with upstream protection and residual-current devices for selective protection. Follow national electrical codes and the manufacturer’s installation instructions for torque settings and derating in elevated ambient temperatures.
