Circuit Breaker 3P 10A C Curve Schneider Electric K60N A9K02310

The Circuit Breaker 3P 10A C Curve Schneider Electric K60N A9K02310 is a three-pole miniature circuit breaker designed to protect three-phase AC installations from overloads and short circuits. With a nominal current rating of 10 A and a C-type tripping characteristic, this device provides balanced protection for distribution boards in residential, commercial and light industrial electrical systems. The compact design is suitable for standard DIN-rail mounting and integration into multi-pole protection schemes where selective tripping and coordination between protective devices are required.

Advantages

This Schneider Electric three-pole breaker combines a clear 10 A nominal rating with a C tripping curve to offer reliable disconnection for moderate inrush currents typical of lighting circuits, small motors and general-purpose loads. The breaker is manufactured to industry quality standards and is intended for straightforward installation and maintenance in common distribution panels. Its three-pole construction ensures simultaneous disconnection of all phases to reduce risks associated with single-phase isolation in three-phase systems.

Suitable for

• Protection of three-phase distribution circuits in residential buildings
• Supply circuits for small commercial outlets and light industrial equipment
• Feeder protection in distribution boards where coordinated selective protection is required
• Circuits with moderate motor start-up currents or grouped lighting loads

When it may not be suitable

This breaker may not be suitable for circuits that require instantaneous high short-circuit breaking capacity beyond its intended class or for systems needing specialized protection curves (such as D-type or K-type) for very high inrush equipment. It is also not appropriate for single-pole applications where single-phase protection or neutral switching is required.

Key specifications

• Poles: 3-pole (simultaneous phase disconnection)
• Nominal current: 10 A
• Tripping characteristic: C curve (moderate inrush tolerance)
• Application type: AC three-phase circuits
• Mounting: DIN-rail compatible miniature breaker

How to use

Mount the breaker on a standard DIN rail inside the distribution board and connect phase conductors to the three input terminals and load conductors to the three output terminals following local electrical codes. Ensure correct upstream and downstream coordination with other protective devices and verify tightness of terminals to the recommended torque values. Use the manual toggle to switch the breaker on and off for testing; allow a qualified electrician to perform insulation and operational tests after installation and before placing the circuit into service.

What to consider before purchase

• Confirm that a 10 A nominal rating and C tripping characteristic match the load profile and coordination requirements of your installation
• Verify that the breaker’s pole count (3P) is appropriate for your three-phase system and switchgear layout
• Check compatibility with the distribution board’s DIN-rail space and terminal conductor sizes
• Ensure short-circuit current rating and selective coordination meet local regulations and upstream protection

Usage recommendations

Use this 3P 10A C Curve breaker in circuits where balanced three-phase protection and moderate inrush tolerance are required. For motor-dominant loads with very high startup currents or for higher fault current environments, consult an electrical designer to select an alternative tripping curve or higher-rated device.
