The BQL340 – EATON 3P40A 240V Bolt-On Breaker is designed for reliable performance in your electrical system. This three-pole circuit breaker offers a 40-amp capacity and operates at 240 volts, ensuring optimal protection for your circuits. Ideal for commercial and residential applications, it provides an essential safety measure for your electrical needs.
The BQL series uses a bolt-on mounting style, which physically secures the breaker to the bus bar with a bolt for a more robust connection — common in commercial panelboards. Eaton's BR and CH series are plug-in breakers primarily used in residential and light commercial loadcentres. The BQL340 is not interchangeable with BR or CH breakers, so it's important to confirm your panel accepts bolt-on breakers before ordering.
The BQL series is considered a harder-to-find product line. Northern Breaker Group specialises in sourcing obsolete and discontinued breakers — if you need a BQL340, contact us for current stock availability and lead times. We serve customers across Canada from our Calgary, Edmonton, and Vancouver locations.
The BQL340 is a 3-pole breaker rated at 240V and 40A, making it suitable for protecting 3-phase circuits in systems where the panel voltage does not exceed 240V. However, it is not rated for 480V or higher voltage 3-phase systems. Always verify your system voltage and panel compatibility before installation, and consult a licensed electrician to ensure compliance with the Canadian Electrical Code (CEC).
