Schneider K60N Automatic Circuit Breaker, 3-Pole, C-Curve, 6kA, 25A

The Schneider K60N automatic circuit breaker is a robust 3-pole protection device engineered for reliable performance in electrical distribution systems. Designed to handle a rated current of 25A at 400V, this unit provides essential safety by disconnecting power in the event of overloads or short circuits. Its compact design and high-quality construction make it a dependable choice for maintaining the integrity of low-voltage electrical installations in various environments.

Advantages

This circuit breaker offers high operational reliability with a mechanical endurance of up to 10,000 cycles, ensuring long-term service in demanding conditions. The C-type tripping curve is specifically optimized for general-purpose applications, providing a balanced response to both standard loads and moderate inrush currents. With a breaking capacity of 6kA and a selectivity class of 3, the device effectively limits fault energy, protecting downstream equipment and wiring from potential damage during electrical surges.

Suitable for

• Residential electrical distribution boards
• Commercial building power management
• Protection of lighting and general socket circuits
• Small industrial machinery installations

When it may not be suitable

This device is not intended for high-voltage industrial grids or specialized applications requiring specific tripping characteristics outside of the standard C-curve profile. It should not be used in environments where the expected short-circuit current exceeds 6kA.

Key specifications

• Number of poles: 3
• Rated current: 25 A
• Tripping curve: C
• Breaking capacity: 6 kA
• Rated voltage: 400 V
• Selectivity class: 3
• Mechanical endurance: 10,000 cycles
• Degree of protection: IP20
• Width: 54 mm

How to use

The Schneider K60N is designed for standard DIN-rail mounting within an electrical distribution enclosure. Installation should be performed by a qualified electrician in accordance with local electrical codes. Ensure that the supply voltage matches the device specifications and that the cables are securely tightened to the terminals to prevent overheating. Once installed, the toggle switch allows for manual control of the circuit, while the internal mechanism automatically trips the breaker during a fault condition.

What to consider before purchase

• Verify that the 25A rating is appropriate for your specific load requirements.
• Ensure the 3-pole configuration matches your three-phase electrical system.
• Check that the available space in your distribution board accommodates the 54 mm width.
• Confirm that the 6kA breaking capacity is sufficient for the prospective short-circuit current at the installation point.

Usage recommendations

Regularly inspect the circuit breaker for signs of thermal damage or loose connections. It is recommended to perform a visual check during routine maintenance of the electrical panel to ensure the device remains in optimal working condition.
