Key Features
- Genuine OEM Construction — Manufactured to the exact electrical and thermal specifications of the original Multiquip CB-10 box heater, ensuring correct heat output and component compatibility.
- Direct Drop-In Replacement — Engineered to install directly into the CB-10 control box housing with no modification to mounting points or wiring connections.
- Confirmed Fitment — Compatible with CB10 and ST-2005S series equipment; cross-reference part number E41 before ordering to confirm applicability to your specific unit.
- Condensation Control — Maintains internal control box temperature to prevent moisture buildup that can damage sensitive electrical components and disrupt pump operation.
- Electrical Safety Assurance — A correctly functioning box heater helps protect contactors, relays, and wiring insulation inside the control enclosure from corrosion caused by condensation.
The heater inside a submersible pump control box serves a critical but often overlooked function: it keeps the interior of the enclosure warm enough to prevent condensation from forming on electrical components. When ambient temperatures drop or humidity rises, moisture can accumulate inside a control box and attack contactors, circuit boards, and terminal connections. A failed or absent box heater accelerates corrosion and increases the risk of electrical faults, nuisance trips, or complete control box failure. Replacing a worn heater promptly is one of the lowest-cost ways to protect a significantly more expensive control assembly.
