Product description
Shipping
The Westinghouse EHB2045 circuit breaker is a purpose-built protective device designed for 480V industrial and commercial electrical systems. With a 45A rating and a 2-pole configuration, this unit protects two hot legs in demanding panels, delivering reliable interruption and dependable circuit protection when you need to maintain uptime and safety.
Key specifications at a glance
- Amperage: 45A
- Poles: 2-Pole
- Voltage: 480V
- Reference: EHB2045
- Intended use: maintenance, retrofit, and replacement in compatible panels
Why this specific breaker stands out
Unlike generic substitutes, the Westinghouse EHB2045 is sized and rated to align precisely with existing Westinghouse panel configurations and 480V distribution layouts. The 2-pole design provides balanced protection across both conductors in a 480V circuit, a crucial consideration for safeguarding motors, feeders, and other high-load equipment in industrial environments.
Ideal use cases
- Panel replacements: swap in when an older 2-pole, 480V unit fails or is worn, minimizing downtime and compatibility risk.
- Retrofits: update legacy electrical systems to current protection standards without overhauling panels.
- Maintenance planning: keep a reliable spare on hand for scheduled or unforeseen service, ensuring quick restoration of service.
Compatibility and installation notes
Before ordering, confirm fit and ratings align with your panel’s specifications. The EHB2045 part number is the most reliable reference for compatibility with systems designed for 480V, 2-pole protection. If your equipment specification calls for a 45A, 2-pole breaker at 480V, this unit is the correct match.
Practical tips to maximize reliability
- Store spare units in a dry, clean environment to protect terminal connections.
- Annotate replacement records with the part number (EHB2045) for future maintenance accuracy.
- Consult a licensed electrician for proper installation and panel-termination procedures to ensure safe, code-compliant operation.
