TCMOV Series Ratings & Specifications
Notes:
1. Average Power dissipation of transients should not exceed 2.0 watts.
2. All 34mm Varistors within the TCMOV34S Series can pass 40kA Non-repetitive Peak Current without opening of thermal disconnect.
† Devices passes Non-repetitive Peak Current surge with possible, safe opening of thermal disconnect.
The same ratings and specifications apply to all devices whether with or without the monitored switch.
To order switch option desired, replace 'M' (With Montitor - Bottom) with 'T' (With Monitor - Top) or 'N' (Without Monitor) in next to last digit of part number.
For additional information please refer to the Part Numbering System section of this document.
