Key Features

• Thermal‑magnetic trip mechanism for overload and short‑circuit protection
• Three‑pole design suitable for 3‑phase 240 V branch circuits
• Manufacturer: Cutler Hammer; Part number/SKU: QC3020H
• Sold as the single specified SKU — confirm model and quantity before ordering

Function and intended use

The QC3020H provides branch‑circuit protection using a thermal‑magnetic trip element that responds to overloads (thermal) and high‑current faults (magnetic). Its three‑pole configuration is intended for protecting three‑phase circuits where simultaneous interruption of all phases is required.

• Protects three‑phase loads on 3‑pole 240 V circuits
• Thermal‑magnetic tripping addresses both sustained overloads and short‑circuit events

Electrical rating and circuit compatibility

Use the QC3020H where a 20 A ampere rating and a 240 V, 3‑pole breaker are required. Confirm compatibility with your panelboard, bus type, and system grounding before installation.

• Ampere rating: 20 A
• Voltage: 240 V
• Poles: 3 (three‑pole configuration)
