High Energy Industrial Thermally Protected

TMOV34S^®Varistor Series

The Littelfuse Industrial TMOV34S series thermally protected varistor

represents a new development in circuit protection. It consists of a 34mm

square format varistor element ( MOV) with an integral thermally activated

element designed to open in the event of overheating due to abnormal

over-voltage, limited current conditions as outlined in UL1449 Feb. 1998

edition.The device has a third lead, an indicator lead, which may be used

to indicate that the MOV has been disconnected from the circuit. This lead

facilitates connection to monitoring circuitry. The TMOV34S devices offer

quick thermal response due to the close proximity of the integrated ther-

mal element to the MOV body. The integrated configuration also offers

lower inductance than most discreet solutions resulting in improved

clamping performance to fast over-voltage transients.

Features

• US Patent for Thermally Protected MOV- Patent # 6636403

• Designed to facilitate compliance to UL1449 for TVSS product.

• Hi Peak Current Rating to 40 kA.

• -55 Deg C to +85 Deg C operating temp.

• Agency Recognition : UL

• Alternative Design available with narrow

3mm wide monitor (right) lead.

Applications

• TVSS Products

AGENCY APPROVALS:

• AC Panel Protection Modules

• AC Line Power Supplies

• AC Power Meters

Recognized by UL under File UL E75901

34mm Devices-Devices are approved as an MOV to UL1449. Devices with

ratings greater than 420VAC are not affected by these abnormal voltage con-

ditions.

• UPS (Uninterruptable Power Supply)

• Inverters

Accelerated Aging Testing-34mm devices comply with Acclerated Aging

Test requirements per. ANSI/IEEE C62.11 and may be used in secondary

surge arrestors.

• AC/DC Power Supplies

• DIN Rail
