Circuit Breaker EATON xPole Home HN-C20/3 3‑pole C curve 20 A 6 kA AC (MPN 194892)

Three-pole miniature circuit breaker EATON xPole Home HN-C20/3 is designed for protection of three-phase AC circuits in residential and light commercial installations. The device features a C curve tripping characteristic and a rated current of 20 A, providing reliable protection against overloads and short circuits. DIN-rail mounting makes it compatible with standard distribution boards and basic electrical panels.

Advantages

The C curve offers balanced response to inrush currents from motors and general-purpose loads while still providing prompt disconnection during fault conditions. Compact three-pole design saves space in distribution boards and ensures simultaneous disconnection of all phases. The device is suitable for common installation environments and follows standard form-factors for straightforward replacement and integration.

Suitable for

• Protection of three-phase circuits in homes and small commercial premises
• Feeder protection for lighting and socket circuits on distribution boards
• Protection of motor circuits with moderate starting currents

Key specifications

• Poles: 3
• Tripping characteristic: C curve
• Rated current: 20 A
• Breaking capacity: 6 kA (AC)
• Mounting: DIN-rail compatible
• Application: AC three-phase circuits

How to use

Install the breaker onto a standard DIN-rail within the distribution board, ensuring correct orientation and secure mechanical engagement. Connect line and load conductors to the corresponding terminals for all three poles, observing proper torque for terminal screws and adhering to local electrical codes. Verify the device is accessible for manual switching and maintenance, and label circuits as required. Test the installation by switching the breaker on and off under no-load conditions before energizing final loads.

Usage recommendations

Confirm compatibility with the system voltage and select upstream and downstream protective devices to coordinate breaking capacity. For circuits with frequent motor starts or high inrush devices, verify that a C curve characteristic is appropriate; where higher inrush is expected consider devices with a different characteristic. Periodically inspect connections for tightness and signs of overheating, and follow local regulations for periodic testing and replacement intervals.
