Ferraz Shawmut's Surge-Trap Type features TPMOV technology inside and is a "no-fuse" SPD
Ferraz Shawmut's Surge-Trap Type is well suited for indoor applications and is an economical replacement for the former Surge Arrestor category. It features TPMOV technology inside and is a “no-fuse” SPD that doesn’t require the use of fuses or additional overcurrent protection. It can be installed upstream or downstream of the main disconnect.
The Surge-Trap Type 1 SPD product line offers a range of voltage configurations, including single-phase, split-phase, three-phase delta and three-phase wye to meet all needs for indoor NEMA Type 2 applications. It also satisfies National Electric Code (NEC) 2008 SPD requirements. The SPD’s features include a fail-safe design, an IP20 enclosure, easy installation and mechanical.
Surge-Trap Type 1 SPD is UL 1449 3rd Edition Approved for Type 1 and 2 applications, including service entrances, feeders and branch circuits. With features for both visual indicators, the Surge-Trap Type 1 SPD suits system voltages from 120V to 600V and MCOV rated 180V to 550V. It has a 200kA short circuit current rating (SCCR) and 40kA 8/20µs surge capacity rating per mode. Agency approvals include ANSI UL 1449 3rd Edition, and meets 2008 NEC Article 280 and 285, UL 96A, NFPA 780 and NEMA LS-1 guidelines.
