HDA36025 - 25 Amp Circuit Breaker

HDA36025 - 25 Amp Circuit Breaker

The HDA36025 molded case circuit breaker is a 3-pole, 25-amp device designed for dependable circuit protection in commercial and industrial electrical distribution systems. Built on the HDA I-Line frame, this plug-in breaker provides straightforward installation within compatible I-Line panelboards and switchboards. With thermal magnetic trip functionality, it delivers reliable overload and short-circuit protection to help safeguard conductors, equipment, and downstream components. Rated for up to 600VAC, the HDA36025 is well suited for maintaining and servicing existing electrical systems that require precise form, fit, and function compatibility.

Engineered for lasting service, this breaker is constructed to handle demanding electrical environments while maintaining consistent protection characteristics. Its interrupting capacity—14kA at 600VAC, 18kA at 480VAC, and 25kA at 240VAC—supports a wide range of applications across multiple voltage systems. For facilities operating legacy I-Line distribution equipment, the HDA36025 offers a direct replacement solution that aligns with original panel specifications and electrical ratings.
