Q2431-70 - 70A Circuit Breaker

Q2431-70 - 70A Circuit Breaker

The Q2431-70 circuit breaker is built for situations where the original breaker layout can’t be changed and the replacement needs to match exactly. This model uses a two plug-on leg design with a third feed-thru leg, making it suitable for panels that were engineered for this specific configuration. With a 70-amp rating and a 240 VAC voltage capacity, it provides dependable circuit protection for systems operating within those limits. The 10 kA interrupting capacity helps protect equipment by opening the circuit during short circuits or overload conditions. Its plug-on mounting style allows qualified professionals to install it efficiently in compatible panels without modifying the existing setup.

Key Features and Benefits

• Matched Breaker Configuration: Designed with two plug-on legs and one feed-thru leg for systems that require this exact layout.
• 70 Amp Rating: Supports electrical loads intended for a 70A breaker as outlined in original system designs.
• Fault Protection: Rated with a 10 kA interrupting capacity at 240 VAC to help stop damaging electrical faults.
• Straightforward Installation: Plug-on design helps reduce installation time when replacing an existing breaker in a compatible panel.
