The HDA260304 is a thermal-magnetic molded case circuit breaker designed to interrupt fault currents and shield wiring from damage in both standard and demanding environments. Its plug-in mounting makes field replacement straightforward, helping technicians restore protection with minimal downtime. The combination of thermal and magnetic trip mechanisms provides accurate trip characteristics, reducing the risk of over-tripping under normal load and quickly responding to short-circuit events.

Why this breaker stands out

Where many breakers rely on a single protection method, the thermal-magnetic design adapts to real-world conditions. The thermal element handles gradual overcurrents, while the magnetic element responds instantly to high faults, delivering dependable protection without compromising the continuity of other circuits in your panelboard or loadcenter. The 600V rating supports a broad range of higher-voltage branch circuits, expanding where and how you can deploy this component.

Ideal for

• Panelboard and loadcenter upgrades in both new installations and modernization projects
• Residential service panels where quick replacement minimizes service disruption
• Commercial electrical rooms and light industrial panels requiring robust, reliable overcurrent protection
