Square D EGB36050 - 50 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Square D EGB36050 is a 50A, 480V, 3-pole bolt-on molded case circuit breaker designed to deliver reliable branch-circuit overcurrent and short-circuit protection in panelboards and load centers. Built for demanding environments, it combines rugged mounting with precise protection to keep electrical systems operational.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, helping maintain continuity under demanding conditions.
• Thermal-magnetic trip unit delivers stable, repeatable protection performance by responding to both overload (thermal) and short-circuit (magnetic) events.
• OEM-compatible design is ready to pair with matching load centers and panelboards, simplifying replacements and upgrades.
• Versatile applications suitable for residential, commercial, and light industrial use, particularly in 3-phase systems where reliable protection is essential.

Ideal for upgrading aging panels or designing new electrical distributions for 480V, 3-pole configurations, the EGB36050 helps you protect feeders, motors, and downstream circuits from damage due to overcurrent and faults. Its bolt-on construction ensures a solid, long-lasting connection in environments where vibration or movement is a factor, such as equipment rooms, commercial buildings, and light industrial facilities.
