• Versatile applications: Suitable for a range of environments—residential, commercial, and light industrial—where dependable protection for 3-phase or single-phase distribution is required.

How it protects your electrical system

The BDL36080 uses a thermal-magnetic trip mechanism that combines two protective layers. The thermal element senses prolonged overcurrent, providing a gradual response to slowly increasing faults. The magnetic element detects high-energy faults instantly, triggering a rapid trip to interrupt power and prevent damage to wiring, devices, and connected loads. The result is predictable breaker behavior, reduced downtime, and enhanced electrical safety across your panelboard or loadcenter.

Ideal use cases

• Replacing a failing 3-pole breaker in Square D panelboards where 80 A protection is appropriate
• Power distribution in small commercial suites, retail spaces, or light industrial equipment rooms that require reliable 3-pole interruption at 600 V
• New installations or upgrades where space efficiency and OEM compatibility streamline the project timeline

Installation and compatibility tips

For optimal performance, pair the BDL36080 with corresponding OEM loadcenters and panelboards designed for thermal-magnetic molded case breakers. Ensure correct alignment and secure mounting in the panel enclosure, and verify that the circuit rating matches the connected load. This 3-pole breaker is purpose-built to protect branch circuits against overcurrent and short circuits, helping maintain system reliability with straightforward replacement in compatible Square D architectures.
