Ditek D200-120/2083Y 200kA/Phase, 100kA/Mode Surge Protector, 120/208VAC Three Phase Wye

The DITEK D200-120/2083Y is a Type 1 industrial surge protective device (SPD) for 120/208 VAC three-phase wye electrical systems using a four-wire-plus-ground configuration. It provides 200,000 amps of surge current capacity per phase, 100,000 amps per protection mode, and a 100,000A short-circuit current rating. Featuring individually fused protection components, per-phase diagnostic LEDs, an audible failure alarm, and Form C dry contacts, the device supports local and remote monitoring of surge protection status. Its NEMA 4X polycarbonate enclosure is designed for demanding commercial and industrial installations and is UL 1449 5th Edition Type 1 Listed.

DITEK D200-120/2083Y Type 1 Surge Protector, 120/208V Three-Phase Wye, 200kA

The DITEK D200-120/2083Y Industrial Surge Protective Device provides transient overvoltage protection for 120/208 VAC, three-phase wye electrical distribution systems with three phase conductors, a neutral, and an equipment ground. Manufactured by DITEK Surge Protection, this hardwired Type 1 SPD is part of the D200 Series, recommended for commercial and industrial electrical panels rated at 600 amps and higher. Its 200kA-per-phase surge current capacity and individually fused protection components help divert damaging electrical transients away from connected equipment. Typical applications include switchboards, main distribution panels, subpanels, and disconnect switches serving fire alarm systems, access control infrastructure, building automation equipment, communication networks, and other sensitive electrical loads.

The D200-120/2083Y provides 200,000 amps of surge current capacity per phase and 100,000 amps per protection mode, with a manufacturer-rated 100,000A short-circuit current rating (SCCR) and a 20kA nominal discharge current rating. Its maximum continuous operating voltage (MCOV) is specified as 150V/300V for the applicable three-phase wye protection modes. Published UL voltage protection ratings are 600V line-to-neutral, 600V line-to-ground, 900V neutral-to-ground, and 1,000V line-to-line. The device incorporates individual fused protection components and per-phase diagnostic LEDs that indicate surge protection operation and grounding status. An integrated audible alarm activates when the protective assembly reaches its end-of-life condition, alerting maintenance personnel that the unit is no longer providing its intended surge protection.

For equipment supervision and remote status monitoring, the DITEK D200-120/2083Y incorporates an audible failure alarm and one Form C dry-contact output. The remote alarm contacts are rated at 0.9A at 240 VAC maximum and provide normally open, normally closed, and common connections for compatible building monitoring equipment. The manufacturer's wiring instructions identify black as normally open, red as common, and white as normally closed for the remote alarm circuit, with connections restricted to appropriate Class 1 circuits. The SPD is housed in a NEMA Type 4X polycarbonate enclosure measuring 6.29 6.29 2.36 inches (160 160 60 mm) and weighs approximately 3.5 pounds (1.59 kg). Its operating temperature range is -31 F to 140 F (-35 C to 60 C), with a maximum relative humidity of 95% non-condensing. The corrosion-resistant enclosure supports suitable indoor and outdoor electrical installations when properly mounted and connected.

The D200-120/2083Y is designed for hardwired installation near a compatible 120/208 VAC three-phase wye electrical panel. It includes a 3/4-inch NPT liquid-tight conduit connection and 30-inch, 10 AWG conductor leads for connection to the electrical distribution system. DITEK recommends a 30A three-pole circuit breaker, with the three phase conductors connected to the breaker and separate neutral and ground conductors connected to their designated buses. Mounting the SPD close to the electrical panel and minimizing conductor length helps reduce additional voltage developed across the connections during surge events. An optional D200-FMK flush-mount kit is available for installations requiring a recessed mounting arrangement. The D200-120/2083Y is UL 1449 5th Edition Type 1 Listed, certified to CSA C22.2 No. 269.1-17, and RoHS compliant, with a 10-year limited manufacturer warranty. It is specifically configured for 120/208V three-phase wye systems and must not be substituted for split-phase, delta, or higher-voltage models. Installation must be performed by qualified electrical personnel in accordance with DITEK instructions, NFPA 70, and applicable electrical codes.
