Universal Replacement Design – The SE series current relay is designed as a general replacement for almost all current relays used in refrigerators, freezers, water coolers, pumps and vending machines. One relay covers a wide range of compressor models, reducing inventory SKU count for distributors and service technicians.
Wide Power & Voltage Coverage – Covers 1/8 HP at 115V up to 2 HP at 230V, making it suitable for fractional horsepower compressors through larger commercial refrigeration compressors. This wide range simplifies selection and stocking.
Reliable Current-Type Starting – Current-type operation switches the start winding based on the compressor’s current draw, ensuring reliable starting even under low-torque conditions typical of capillary tube systems. No voltage sensing required.
Easy Installation – Plug-on design allows the relay to be pushed directly onto the compressor terminals, eliminating complex wiring and reducing assembly time on the production line or during field service.
Compact & Space-Saving – Small footprint fits tight compressor terminal enclosures, suitable for compact refrigeration systems.
Durable Construction – High-quality coil and silver alloy contacts provide long electrical life, withstanding the high inrush currents of compressor starting.
Stable Bulk Supply – Standard models ship in 15–25 days, supporting rolling replenishment and reducing inventory capital occupation.
OEM & ODM Support – Custom logo, packaging, voltage, and terminal type available. Can produce according to customer specifications.
Batch Traceability – MTC with every shipment; SGS/BV third-party inspection supported.
Export Packaging – Seaworthy carton and pallet packaging, suitable for long-distance ocean shipping.
