Multiquip 0601820845 Over Current Relay

The Multiquip 0601820845 Over Current Relay is a genuine OEM component designed for DCA series ultra-silent and super-silent diesel generators, including the DCA125, DCA150, DCA220, DCA45, DCA70, DCA85, DCA25, and DCA100 model families. This is a direct OEM replacement sourced through authorized Multiquip supply channels, ensuring the part meets the original electrical specification for your unit. Confirmed fitment spans a wide range of DCA models including DCA125SSJU, DCA150SSVU, DCA220SSVU, DCA70SSJU, DCA45SSIU2, DCA25USI, and many additional variants. Keep a verified replacement on hand to avoid extended downtime on time-sensitive power generation applications.

Key Features

• Genuine OEM Electrical Specification — Matches the original relay's trip threshold and switching characteristics, ensuring the protection circuit responds correctly under fault conditions.
• Drop-In Replacement — Engineered to install directly into the existing relay mounting position on DCA series generator control panels without modification to wiring harnesses or terminals.
• Broad DCA Series Fitment — Compatible with a wide range of ultra-silent and super-silent DCA generators including DCA25, DCA45, DCA70, DCA85, DCA100, DCA125, DCA150, and DCA220 model variants.
• Overcurrent Protection Restored — A failed or worn relay leaves the generator vulnerable to load-side electrical faults; replacing it with part this part restores the circuit's ability to detect and interrupt excessive current draw.
• Electrical Safety Compliance — The over current relay is a primary safety device in the generator's protection circuit; using a genuine OEM part maintains the intended trip rating and prevents nuisance tripping or failure to trip under a true fault condition.

An over current relay monitors the electrical output of a generator and automatically interrupts the circuit when current levels exceed a safe threshold. This protects both the generator's internal windings and connected equipment from damage caused by overloads or short-circuit events. When the relay fails or becomes miscalibrated, the generator may shut down unexpectedly under normal loads, fail to protect against genuine faults, or cause damage to downstream electrical equipment — making prompt replacement with the correct OEM part critical to safe, reliable operation.
