Immediate shipment! Featuring 25kA, 50kA, 80kA and 100kA models

· Protects facilities and equipment against catastrophic lightning strikes and internally generated electrical transients

· Tested single-pulse surge current capacity per NEMA 2.2.9 and 3.9 recommendations

· Comes with pre-wired pigtail terminals to streamline installation

· Features arc-quenching, sand-packed design

· Backed by certified, independent laboratory performance test reports

· 3-day or less delivery

Proven technology: TransEnd delivers worry-free performance in a reliable, innovative design. The tested single-pulse surge current capacity (per mode) is tested per NEMA recommendations. Sand-packed MOV arrays equally share current to suppress transients before they reach sensitive loads while capacitors filter out high-frequency noise and low-level transients. TransEnd is designed and tested to withstand surge currents in accordance with ANSI/IEEE recommendations.

Instantaneous protection: TransEnd responds immediately and reliably to repeated high-current lightning incidents and other transient voltage surges. All TransEnd models are designed to exceed the minimum performance criteria of Bellcore and withstand larger impulses referenced in IEEE.

Superior internal construction: TransEnd’s innovative design ensures dependable operation. The suppression filter components are bolted directly to copper bus bars, lowering system impedance and clamping voltage and increasing reliability.

Status indicators: LEDs for each phase illuminate to clearly indicate protection is active.

Prewired: For ease of installation, TransEnd is equipped with 24-inch, stranded #10 AWG pigtail conductors. The conductors can be cut to fit the application and to permit the shortest connection for optimum performance.

Flex Conduit: For easy field installation, TransEnd is factory-equipped with a flexible conduit and a versatile ¾-inch-diameter fitting, allowing the installer to use either flex or conduit.

Rugged, Compact Enclosure: Measuring only 7"W x 7"H x 5"D, TransEnd easily installs in tight spaces. The NEMA 4 fiberglass-reinforced plastic (FRP) housing features a nonremovable cover for protection against tampering.

Warranty: Five-Year Product Warranty

Modes of Protection: L-N, L-G, N-G, L-L EMI/RFI
Noise Rejection: Filtering Attenuation Frequencies

Method of Operation
When a transient surge exceeds the normal system voltage, TransEnd responds within nanoseconds and changes state from a high-impedance open circuit to a low-impedance shunt (short circuit). Connected in parallel with the facility’s loads, TransEnd diverts damaging current away from sensitive loads while simultaneously reducing (clamping) the high transient voltage to harmless levels. Upon the end of the transient event, TransEnd automatically returns to its normal operating condition without service interruption.

Applicable approvals and standards
UL 1449, 2nd Edition: Underwriters Laboratories standard that establishes requirements for surge suppression safety.

CUL: Canada Underwriters Laboratories standard that establishes requirements for surge suppression safety.

Critical considerations when selecting surge protection devices
Two primary factors influence the minimum life expectancy of a surge protection device: the frequency and the intensity of surge-causing events (for example, lightning- induced surges, power factor correction capacitor and load switching). For optimum protection, it is imperative to properly select the device appropriate for the following factors:

    1. the facility’s exposure to surges (rather than to the size of the load or service);
    2. the criticality or value of the equipment being protected;
    3. the location of the surge protection device within the facility’s power distribution system; and
    4. the level of power disturbances generated by the facility’s electrical and electronic equipment.

Based on your project and protection requirements, we can help you determine which devices and installation locations will best achieve your objectives.
