The Linear 2500-543 is an OEM replacement relay designed for use in Linear and OSCO gate operator systems. Rated at 230V coil. Relay housing, electrical-grade coil and contact materials. Contact configuration: 3PDT (Triple Pole Double Throw). This part is manufactured by Nortek/Linear LLC/Linear PRO Access and is available through authorized distributors.
A: The 2500-543 uses a 230V coil voltage, making it appropriate for gate operator systems wired for European-standard or higher-voltage North American control circuits.
A: The 2500-541 uses a 24 VAC coil while the 2500-543 uses a 230V coil. Both share the same 3PDT contact configuration but are not interchangeable due to the coil voltage difference.
A: 3PDT means Triple Pole Double Throw - three independent poles each switching between two output contacts, providing versatile multi-circuit switching capability.
A: No official NEMA enclosure rating has been published for this part. It is an OEM relay intended for installation inside a gate operator control enclosure.
A: Always verify coil voltage, contact current rating, and pin layout against your control board schematic before replacing this relay with a third-party equivalent.
