EDB34045 SQUARE D 3P 45A 480V
The EDB34045 from Square D is a durable 3-pole circuit breaker designed for applications up to 45 amps at 480 volts. This reliable breaker ensures optimal protection for your electrical system, enhancing safety and efficiency. Ideal for commercial and industrial environments, it guarantees smooth operation and dependable performance under demanding conditions.
The EDB34045 carries an interrupting rating of 18kA at 480V. This is suitable for many commercial and light industrial distribution systems. If your available fault current exceeds 18kA, you may need a higher-interrupting-capacity frame — contact our team and we can help identify the right Square D MCCB for your fault study results.
Availability can vary as Square D periodically updates its MCCB lineup. Northern Breaker Group specialises in both current-production and obsolete or hard-to-find breakers across Canada. Whether the EDB34045 is a current or legacy part, we can source it — reach out for a quote from our Calgary, Edmonton, or Vancouver counters.
The EDB34045 can serve as either a branch-circuit or a feeder/main breaker, depending on the panelboard configuration and whether the installation is code-compliant for that use. Its 45A, 3-pole, 480V rating makes it versatile for both roles in commercial and industrial panels. Always verify with your panelboard's documentation and a licensed electrician to ensure the installation meets Canadian Electrical Code (CEC) requirements.
