Square D | FAB36100 | Circuit Breaker | 100A | 3-Pole | 600V | 25kA | Bolt-On

Square D FAB36100 circuit breaker delivers dependable, purpose-built protection for three-phase power systems. This 100A, 3-pole, 600V bolt-on breaker is designed for maintenance, retrofit, and replacement scenarios where exact specifications matter. When you need a like-for-like replacement or an upgrade in a Square D panel that accepts bolt-on devices, FAB36100 is the reference you rely on.

Key specifications

• Amperage: 100 A
• Poles: 3-Pole
• Voltage rating: 600 V
• Interrupting rating: 25 kA
• Mounting: Bolt-On

Why this matters in real-world setups

In three-phase electrical distributions, a 100A, 3-pole breaker protects circuits serving motors, pumps, and other heavy loads. The 25 kA interrupting rating provides a margin of safety for higher fault currents commonly found in commercial and light industrial facilities. Bolt-on mounting offers a secure, rigid installation that resists vibration and panel movement, helping maintain consistent tripping performance over time.

Ideal use cases

• Replacement for existing Square D bolt-on breakers in compatible panels
• Retrofits when upgrading to a 3-phase 100A protection scheme
• Maintenance and service in commercial/industrial electrical rooms

Compatibility and installation notes

Important: Confirm fit and ratings before ordering. The part number FAB36100 is the best reference for compatibility with your Square D panel. This is a bolt-on device—plan for proper mounting hardware and torque per panel specifications, and ensure the panel accepts 3-pole, 100A, 600V devices with a 25 kA rating.

What sets FAB36100 apart

• Authentic Square D design and specifications aligned with standard panels that accept bolt-on breakers
• Explicit 3-pole, 100A protection for balanced three-phase circuits
• High fault-current capability (25 kA) for robust protection in dynamic load environments
