Description
The Leviton P2120-B is a high-performance P Series Type 1 Surge Protective Device (SPD) designed to shield sensitive electronics from damaging voltage transients. Engineered for 120/240V split-phase systems, this device acts as a primary defense for residential and light commercial applications. As a Type 1 SPD, it offers the flexibility of being installed on either the line or load side of the main service disconnect, making it a critical component for meeting NEC Article 230.67 requirements. These code updates require surge protection for all dwelling units, as well as dormitory units and patient sleeping rooms. By utilizing thermally protected Metal Oxide Varistors (MOVs), the P2120-B safely diverts surges up to 50kA, ensuring your facility remains compliant and your equipment remains operational.
Key Features
- Code Compliance: Ideal for meeting 2020 and 2023 NEC requirements for dwelling units, hotels, and limited-care facilities.
- Robust Surge Capacity: Provides a 50kA per mode/phase surge current rating to handle high-energy transients.
- NEMA 4X Enclosure: Housed in a durable, polycarbonate enclosure that is rated for indoor or outdoor use, protecting against harsh environmental conditions.
- Advanced Monitoring: Features dual-layered diagnostics with an LED status indicator and an audible alarm to alert you if protection is ever compromised.
- Remote Monitoring: Includes Form C dry contacts for integration into building management systems or remote monitoring setups.
- Thermally Protected MOVs: Advanced surge technology prevents hazardous failure modes by safely disconnecting the MOV in the event of an extreme overvoltage.
