HDL36150 - 150 Amp Circuit Breaker

HDL36150 - 150 Amp Circuit Breaker

The HDL36150 150 Amp H-Frame Circuit Breaker is your go-to protection solution when your power system demands reliability and precision. Designed for serious duty, this thermal-magnetic 3-pole breaker supports systems up to 690 V AC (50/60 Hz) with a breaking capacity of 14 kA at 600 V AC—and even higher fault-current handling at lower voltages—so you can count on durable protection against overloads and short circuits. The intuitive front-facing semi-transparent cover gives you a quick visual of the breaker’s status, while field-installable accessories and a snap-in terminal system let you adapt to busbar or lug configurations easily—saving time on install and lowering inventory complexity. Whether you’re safeguarding an industrial control panel, commercial distribution system or a high-demand residential setup, this breaker delivers dependable performance built to last.

Key Features and Benefits

• High breaking capacity (14 kA at 600 V AC): Built to withstand significant fault currents, giving you confidence that the circuit can interrupt high-energy events without compromising safety.
• Thermal-magnetic sensing in each pole: Combines overload (thermal) and instantaneous short-circuit (magnetic) protection to safeguard your equipment reliably and prolong its life.
• Front-facing semi-transparent cover: Lets you monitor the status without removing panels or covers, reducing downtime and simplifying inspections.
• Field-installable accessories: Adds installation flexibility so your system can be tailored on-site rather than relying on preconfigured parts only.
• Snap-in terminal conversion (busbar ↔ lug): Makes switching between mounting options fast and straightforward, enhancing adaptability and lowering labour time.
