Multiquip Y0601820839 Over Current Relay DENYO - OEM Replacement Part

The over current relay is a critical electrical protection component that monitors generator output current and automatically disconnects the system when current levels exceed safe operating thresholds. This Denyo-manufactured relay protects the generator windings, control circuitry, and connected equipment from damage caused by overload conditions, short circuits, or other electrical faults. In Multiquip super silent generator models, this relay integrates directly into the generator control panel wiring system, working in conjunction with current transformers (CT 1-5) to continuously monitor electrical output across all three phases.

According to Multiquip wiring diagrams, this relay connects through the generator control circuit and operates as part of the comprehensive protection system that includes voltage regulation and frequency monitoring. Proper relay function is essential for preventing catastrophic generator damage during sustained overload conditions. Technicians should verify relay operation during routine maintenance intervals and replace immediately if nuisance tripping, failed load acceptance, or no-trip conditions during overload testing occur.

This over current relay is compatible with the following Multiquip super silent generator models:

• DCA150SSJU4F, DCA150SSJU4F2, DCA150SSJU4F3
• DCA25SSIU4F, DCA25SSIU4FC8
• DCA40SSKU4F2
• DCA600SSV4F3
• DCA70SSIU4F, DCA70SSJU4F
• NGA100SSPUL
