Dean Technology, Inc. today announced the newest edition to its CKE suppression products, the TPM series. These thermally protected MOV suppressors have a high surge current capability, meet UL 1449 3rd edition, and provide floating remote signaling contacts for fault indication.

The TPM Series suppressors integrate a thermal disconnect apparatus in series with the MOV disc; ensuring that if the unit overheats it is disconnected from the circuit. This helps to eliminate common failure modes that have historically occurred in the field with MOV components in uses including lightning protection, and inductive or capacitive load switching. The fail-safe nature of the CKE TPM Series offers extra assurance against any risk of fire or similar negative event.

“The TPM Series is a great example of how Dean Technology is working tirelessly to keep pace with the ever evolving standards for electrical components,” said Larry Cagle, Dean Technology’s director of technology development. “We want to ensure we have the most modern products available in our particular markets, while continuing our mission to provide a full range that covers any new or historic need. These TPM devices hold true to that, and also our commitment to offer products at the best possible value.”

TPM Series components are currently available in two versions. The TPM-25 has a surge rating of 25 kA and the TPM-50 is rated at 50 kA. Each come in a broad range of voltage ratings from 150 volts up. The TPM-50 is currently approved for UL 1443 3rd edition for Type 1 and 2, and CSA for Type 2. The TPM-25 meets all these same standards, and is being reviewed for certification now. All of the TPM Series parts are available immediately directly from Dean Technology, or through any approved sales partner or distributor.
