Square D EGB36100 - 100 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Square D EGB36100: 100 A, 600 V, 3-Pole Bolt-On Circuit Breaker for Solid Panel Protection

The Square D EGB36100 is a bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. With a 100 A rating and a 600 V capacity, this three-pole unit is engineered to handle demanding electrical environments while maintaining precise protection performance across three phases.

Why this bolt-on breaker stands out

• Secure bolt-on mounting ensures a rigid, vibration-resistant bus connection that stays solid even in dynamic or vibration-prone installations.
• Thermal-magnetic trip unit provides stable, repeatable protection, combining overload (thermal) and short-circuit (magnetic) responses for reliable trips when they’re truly needed.
• OEM-compatible design works seamlessly with matching Square D load centers and panelboards, simplifying installation and maintenance.
• Versatile applications suited for residential panels, commercial electrical rooms, and light industrial equipment—where consistent protection matters most.
