EATON HN-C20/1 Miniature Circuit Breaker MCB 20A 1-Pole C-Curve 6kA 1 Module

The EATON HN-C20/1 is a high-quality miniature circuit breaker (MCB) designed for reliable overcurrent protection in residential, commercial, and light industrial applications. With a rated current of 20 A and a C-curve tripping characteristic, it provides optimal protection for circuits with moderate inrush currents, such as lighting and general-purpose loads. This 1-pole breaker occupies just 1 module width (approx. 18 mm) on a DIN rail, making it space-efficient for distribution boards.

Advantages

• Compact 1-module design saves space in electrical panels.
• C-curve characteristic ensures selective coordination and reduces nuisance tripping.
• High breaking capacity of 6 kA meets stringent safety standards.
• Robust screw terminals accept conductors up to 25 mm² for easy installation.
• Compliant with IEC/EN 60898-1 for global acceptance.

Suitable for

• Residential lighting and socket circuits
• Commercial office power distribution
• Light industrial control panels
• General-purpose overcurrent protection
