Ideal applications and use cases

Designed for facilities that rely on robust electrical isolation, the ER325N is an excellent choice for:

• Industrial maintenance crews performing scheduled servicing on 240V equipment
• Retrofit projects where existing disconnects are out of date or no longer meet current specs
• Replacement scenarios where matching the original 2-Pole, 240V configuration is critical for system compatibility

Practical guidance for buying and installation

Before you order, confirm that the ER325N fits your enclosure and matches the ratings of your circuit. The part number is your strongest reference for compatibility, so use it to verify footprint, mounting, and connection arrangements in your panel or switchgear. If you’re upgrading multiple circuits or coordinating with a larger control scheme, document the exact switch configuration (2-Pole, 400A, 240V) to ensure seamless integration with existing safety and control devices.
