HQNP3040 | Circuit Breaker | 3-Pole | 240V

HQNP3040 is an industrial circuit breaker designed for precise compatibility in 3‑phase 240V applications. Built for maintenance, retrofit, and replacement projects, this 3‑pole device ensures you can restore reliable protection where exact specs matter.

Key specifications

• Poles: 3‑Pole
• Voltage: 240V

Why this matters for your system

In three‑phase electrical setups, every phase shares the same protection timing. The HQNP3040’s 3‑pole design ensures synchronized interruption across all conductors, helping prevent uneven load, arcing, and unexpected downtime. By using the correct part number as your reference, you minimize compatibility risks and simplify inventory management for service teams.

Ideal use cases

• Replace a worn or failed breaker in panels that specify HQNP3040, maintaining system behavior and protection characteristics.
• Retrofit: Upgrade or modernize existing 3‑phase gear with a proven, matching 240V 3‑pole device.
• Replacement: Stock a reliable spare for quick field swaps, reducing downtime during faults or routine service.

How to verify fit and compatibility

Before ordering, confirm fit and ratings as noted. The HQNP3040 part number is the best reference for compatibility with your equipment. Check your panel labeling, bus configuration, and any current or interrupting capacity requirements against your service manual to ensure a seamless match.

Practical notes for technicians

Keep a small inventory of correctly matched breakers on hand to speed up maintenance windows. If your documentation references HQNP3040, this exact 3‑pole, 240V model is designed to slot into compatible frames without modifications, preserving protection schemes and wiring layouts.
