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.
AGENCY APPROVALS:
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.
Accelerated Aging Testing-
34mm devices comply with Acclerated Aging
Test requirements per.ANSI/IEEE C62.11 and may be used in secondary
surge arrestors.
