HFA3020L | Circuit Breaker | 20A | 3-Pole | 600V

HFA3020L is an industrial circuit breaker designed for dependable three‑phase protection in demanding electrical distributions. With a 20A trip rating across 3-Pole configurations and a 600V maximum voltage rating, this device is built to guard motors, drives, and control panels in manufacturing, facilities, and heavy equipment environments.

Key specifications at a glance

• Amperage: 20A
• Poles: 3-Pole
• Voltage rating: 600V

Why this matters for your system

Three‑pole protection means all three phases are switched together, reducing the risk of phase imbalance and equipment damage in 3‑phase machinery. The 600V rating aligns with common industrial power networks, delivering reliable protection where higher voltage systems are in play. This makes HFA3020L a practical, durable choice for ongoing maintenance, retrofits, and replacement projects that require exact spec alignment.

Ideal use cases

• Maintenance and servicing of 3‑phase panels and equipment where a precise HFA3020L specification is needed
• Retrofit projects to bring legacy systems up to current protection standards
• Replacement parts for industrial control panels that require a 3‑pole, 20A, 600V circuit breaker

How to ensure a proper fit

Before ordering, confirm fit and ratings match your equipment. The HFA3020L part number is the most reliable reference for compatibility, helping you avoid mismatches and minimising downtime.

Practical notes for installation and reliability

• Use in systems that require simultaneous tripping of all three phases to protect the load and upstream wiring
• Plan for standard spare parts in industrial panels to reduce service interruptions
• Store and handle with circuit power removed to ensure safe replacement and testing after installation
