The Multiquip K56 Heater 460V ST-4125 CB14 is a genuine OEM heater element designed for the CB14 control box and ST-4125 submersible pump system. As a factory-sourced component, the part delivers the correct 460V rating required for proper operation within the control box assembly — no guesswork on voltage compatibility. This part is confirmed to fit the CB14 and ST-4125, making it a direct replacement when servicing or restoring your submersible pump system.
Key Features
- Correct Voltage Rating — Rated at 460V to match the exact electrical specification of the CB14 control box, ensuring proper thermal output and safe operation within the assembly.
- Genuine OEM Component — Sourced directly from Multiquip, this heater element meets the same manufacturing standards as the original part installed at the factory.
- Confirmed Fitment — Engineered specifically for the CB14 control box and ST-4125 submersible pump system; installs as a direct swap for the original heater element.
- Protects Control Box Electronics — A functioning heater element prevents moisture condensation inside the control box enclosure, shielding sensitive electrical components from corrosion and short-circuit risk.
- Electrical Safety Compliance — Using the correct OEM-rated heater element in a control box application is critical to maintaining proper circuit protection and avoiding overload conditions within the enclosure.
The heater element in a submersible pump control box serves as an anti-condensation device. By maintaining a slightly elevated temperature inside the enclosure, it prevents moisture from forming on electrical contacts, circuit boards, and relay components — particularly in outdoor or high-humidity environments. When this heater fails, condensation can accumulate inside the control box, leading to corrosion, intermittent faults, or complete electrical failure of the pump control system.
