Square D BDL36100 - 100 A, 600 V, 3-Pole Circuit Breaker | AmpState

The Square D BDL36100 is a 3-pole molded case circuit breaker rated for 100 A and up to 600 V, designed to protect branch circuits inside panelboards and load centers. Available through AmpState, this device delivers reliable overcurrent and short-circuit protection to keep electrical systems safe and compliant.

Why this breaker stands out

• Compact molded-case design maximizes panel space so you can fit more circuits without crowding the busbars.
• Thermal-magnetic trip unit provides stable, repeatable protection by responding to both prolonged overloads and instantaneous short circuits, reducing nuisance tripping while maintaining safety.
• Three-pole configuration ideal for balanced 3-phase distribution, making it suitable for commercial and light industrial applications as well as residential panels that require 3-pole protection.
• Broad compatibility engineered to work with matching OEM loadcenters and panelboards, ensuring proper fit, alignment, and coordinated protection with other devices in the same system.
• Versatile application range supports residential, commercial, and light industrial environments where dependable branch circuit protection is essential.

What it protects and how it helps

The BDL36100 guards branch circuits from overcurrent and short circuits, helping prevent wiring damage, fire hazards, and equipment failure. Its thermal element handles sustained overloads, while the magnetic element rapidly interrupts during high-maultipoint fault conditions. This combination yields dependable protection with predictable trip behavior, which is crucial for maintenance schedules and system reliability.
