Information About KC34125
The KC34125 is part of the legacy Square D KC Series and uses an I-Line mounting configuration for compatible electrical distribution equipment. Its thermal-magnetic trip technology combines fixed thermal protection with adjustable magnetic protection for LI long-time and instantaneous trip functions. The breaker supports 240 VAC, 480 VAC, and 250 VDC applications with interrupting ratings of 100 kA at 240 VAC, 65 kA at 480 VAC, and 10 kA at 250 VDC. Available options include shunt trip, auxiliary switch, alarm switch, undervoltage release, and load-side lugs.
Key Features:
- 125 A Rating: Provides overcurrent protection for electrical systems requiring a 125 A circuit breaker.
- Three-Pole Configuration: Designed for three-phase electrical distribution applications.
- Multi-Voltage Operation: Rated for 240 VAC, 480 VAC, and 250 VDC applications.
- High Interrupting Capacity: Provides 65 kA interrupting capacity at 480 VAC and 100 kA at 240 VAC.
- Thermal-Magnetic Protection: Combines fixed thermal overload protection with adjustable magnetic protection.
- LI Trip Functions: Provides long-time and instantaneous trip operation.
- I-Line Mounting: Designed for plug-in installation in compatible Square D I-Line panelboards and switchboards.
- Accessory Options: Supports shunt trip, auxiliary switch, alarm switch, undervoltage release, and load-side lug configurations.
The KC34125 delivers the reliability and precision required for commercial and industrial electrical distribution and overcurrent protection applications.
