AI Overview
A 440V surge protection device (SPD) is crucial for protecting industrial machinery and electrical panels from high-voltage spikes, typically featuring a maximum continuous operating voltage (
) of 440V-480V or higher to prevent false tripping. These are commonly Type 1 or Type 2, available in 3-phase, 4-pole, or compact pluggable configurations, with surge capacities often ranging between 40kA and 200kA.
Key Features and Options:
- Voltage Rating: Specifically designed for 440V AC systems, with some models offering maximum operating voltages () of 440V, 385V, or higher.
- Types: Type 1 (main panel), Type 2 (sub-panels/machinery), and compact 2-pole or 4-pole modules.
- Typical Specifications: Common options include 40kA (maximum discharge current ) and 20kA (nominal discharge current).
- Performance: Features pluggable modules, remote signaling for maintenance, and compliance with IEC 61643-11 or UL1449 standards.
Common Manufacturers/Models:
- Schneider Electric ASCO Model 440 (120-600VAC).
- Intermatic PANELGUARD 440/480V 3Ph.
- Hager 4P Type 2 40kA.
- Eaton SPD3200 (440V AC, 200kA).
