FHL36020 - 20 Amp Circuit Breaker

FHL36020 - 20 Amp Circuit Breaker

The Schneider Electric FHL36020 is a precision‑engineered molded‑case circuit breaker that’s built to deliver dependable protection for demanding electrical systems. Rated at 600 V and 20 A with a 3‑pole configuration, this breaker is designed to shield circuits from both slow overloads and sudden short‑circuit faults through its thermal‑magnetic trip mechanism. Whether you’re specifying gear for commercial applications or upgrading motor control centres, this breaker brings installation flexibility and lasting performance to the table.

Key Features and Benefits

• High voltage and current rating: This unit delivers 20 A at up to 600 VAC, making it suitable for heavy‑duty use in industrial and commercial settings.
• Thermal‑magnetic trip unit: Combines long‑time (thermal) protection for overloads and instantaneous (magnetic) protection for short circuits, enabling reliable safeguarding of your equipment.
• Lug‑to‑lug terminations with unit mount design: Both line and load connections use lugs for ease of installation and secure mounting, helping you minimise downtime during swap‑outs.
• Compact footprint: With dimensions of approx. 6.4″ height × 4.5″ width × 4.13″ depth, the FHL36020 fits into space‑constrained panels yet still offers the strength you require.
• Premium build: Crafted by Schneider Electric for long service life and reliable performance in demanding environments.
