Eaton ZD16709 ZoneDefender PRO Type 2 Surge Protector 240V Single-Phase with Dual-Redundant MOV Networks

ZD16709 - ZoneDefender PRO Type 2 AC Surge Protector | 240V Single-Phase

The ZD16709 is a high-performance AC surge protection device (SPD) from Eaton's MTL Crouse-Hinds ZoneDefender PRO series. Designed for Type 2 applications at service entrances and branch circuit panels, this compact unit delivers robust protection against lightning-induced surges, switching transients, and high-frequency electrical noise that can damage sensitive equipment.

The ZoneDefender PRO platform combines high-energy MOV technology with dual-redundant varistor networks - ensuring your facility remains protected even if one component fails. No operator intervention is required; the device resets automatically and is maintenance-free.

• Commercial building electrical panels
• Industrial facility power distribution
• Data center server infrastructure
• Healthcare and medical equipment protection
• Telecommunications systems
• Renewable energy installations (solar inverters, wind turbines)

1. No Single Point of Failure
Unlike standard surge protectors, the ZoneDefender PRO features dual-redundant MOV networks. If one varistor fails, the redundant network continues to provide protection - ensuring your critical equipment is never left vulnerable.

2. Fully Automatic Operation
The ZD16709 reacts immediately to transient events, clamping voltage surges without causing unnecessary leakage losses during normal operation. After the surge passes, the unit resets automatically - no maintenance, no downtime, no operator intervention.

3. All-Mode Protection Coverage
Many surge protectors only protect line-to-neutral. The ZD16709 provides comprehensive protection across all four modes: Line-Neutral, Line-Ground, Line-Line, and Neutral-Ground.

4. Built-In Safety Features
The device incorporates solid-state diagnostic capabilities with built-in overcurrent and thermal fusing protection - automatically disconnecting under sustained overvoltage conditions to prevent fire hazards.

5. Compact, Versatile Installation
Designed for both new construction and retrofit applications, the ZD16709's compact footprint fits easily into crowded electrical panels. The UL Type 1 / Type 4 enclosure supports both indoor and outdoor installations.
