Two terminal type for bipolar protection between two points, e.g. plus to minus, or plus to ground, or minus to ground. Mounting legs are terminals on 2 3/8” centers. Also available with top screw terminals. The housing is insulating, 1.6” X 1.0” X 2.0” H.

Three terminal type for bipolar protection between three points, e.g. plus to minus, plus to ground, minus to ground. Mounting legs are terminals on 2 3/8” centers. The center wire is for ground connection. Also available with top screw terminals. The housing is insulating, 1.6” X 1.0” X 2.0” H.

Two terminal type for bipolar protection between two points, e.g. plus to minus, or plus to ground, or minus to ground. Enclosure painted steel, mounting centers (4 holes) 5” X 1 1/8”. Housing 4 1/2” X 2 7/8” X 2 5/8” H.

For use on series or T connection, unlimited load current. Bipolar operation, either polarity of surge equally clamped. 2 wire standard AAR terminal block provided. Steel (painted) enclosure 4.50" X 2.88" X 2.62" H. Response one nanosecond, no follow current, self restoring instantly when voltage returns to normal.

Three terminal type for bipolar protection between three points, e.g. plus to minus, plus to ground, minus to ground. Enclosure painted steel, mounting centers (4 holes) 6 3/4” X 2”. Housing 6” X 4” X 3” H.

High energy, high surge capability. Two and three terminal surge arrester. Enclosure is painted steel, mounting centers 10 ¾” X 6”. Housing 10” X 8” X 4”. Two terminal type for bipolar protection between two points, e.g. plus to minus, or plus to ground, or minus to ground. Three terminal type for bipolar protection between three points, e.g. plus to minus, plus to ground, minus to ground.

Two terminal surge arrester, 5/16”-18 X 3/4” long threaded studs. Enclosure is insulating 2” dia. X 1 ½” high. Two or more may be placed in parallel for higher surge current capability. May be connected plus to minus, or plus to ground, or minus to ground.

Same performance characteristics as the LPC 11550. Terminations are wires, mounting through ½” knock-out or L bracket.

Transmitter, 4-20 ma lightning and surge protector. Installation at the transmitter (or under the transmitter cover). Miniature in size, 1/2” X 5/8” X 11/4”. Protection rating line to line and each line to ground, 30 KA on 8/20 µs wave. Three AWG #16 leads, red to plus, black to minus, green to ground. Response less than one nanosecond. Initial clamp voltage 68V peak, dropping to 30V for one to 10,000 amperes surge current. Bipolar operation, either polarity of surge equally clamped.
