Information About 57120-M3
The Leviton 57120-M3 is a modular Type 2 surge protective device designed for 120/208 V 3-phase Wye distribution panels. Built with replaceable and redundant surge modules, it provides continuous high-capacity protection of up to 150 kA per phase, safeguarding electrical systems from transient overvoltages. Its NEMA 12 steel enclosure, dual-stage fused design, and advanced diagnostics make it ideal for demanding commercial and industrial environments. Real-time status LEDs, an audible alarm, and remote monitoring capabilities ensure timely alerts and maintenance readiness.
Key Features:
- High Surge Capacity: 150 kA per phase (300 kA total) with 4-mode protection (L-N, L-G, N-G, L-L).
- Replaceable Surge Modules: Modular design with 3× 7120 and 1× 8120-GN units for easy maintenance.
- Advanced Diagnostics: Real-time status LEDs, audible alarm, and Form C dry contacts for remote monitoring.
- Robust Construction: NEMA 12 powder-coated steel enclosure with UL 94 V-2 flammability rating.
- Noise Filtering: –20 dB to –40 dB attenuation at 5 kHz–10 MHz for improved power quality.
- Environmental Resilience: Operates from –20 °C to +40 °C and in 5–95 % non-condensing humidity.
- Standards Compliance: UL 1449 3rd Edition, CSA, and ANSI/IEEE C-62.41 & C-62.45 (Categories A, B, C).
- Flexible Wiring: Parallel-hardwired terminal blocks accept up to #3 AWG wire for easy installation.
The 57120-M3 delivers reliable, high-performance surge protection for critical electrical infrastructure, ensuring operational continuity and equipment longevity.
