Q2430-90 - 90 Amp Circuit Breaker

Q2430-90 - 90 Amp Circuit Breaker

The Q2430-90 90 Amp Circuit Breaker is used in 3-phase electrical panels where a 90 amp breaker with a plug-on connection is required. It’s rated for 240 VAC and has a 10kA interrupting capacity, making it a common fit in many commercial and light industrial systems. This breaker is often selected when replacing an existing unit and the panel layout, ratings, and mounting style need to stay the same. The plug-on design helps speed up installation and reduces downtime, which is especially helpful during service work or routine maintenance.

Key Features and Benefits

• 90 Amp Rating: Matches circuits designed to run at a 90A load without over-sizing or under-protecting the system.
• Plug-On Style: Allows for quicker installation in compatible panels with less effort during replacement.
• 10kA Interrupting Capacity at 240 VAC: Suitable for many standard commercial and light industrial electrical applications.
• 3-Pole Configuration: Built for 3-phase systems that require consistent protection across all phases.
