Suntree 2P AC Surge Protector 500VAC 40KA — Professional-Grade AC Surge Protection
Shield your electrical installations from destructive voltage surges with the Suntree 2P AC Surge Protective Device (SPD), engineered for dependable surge protection in AC power distribution systems. Rated at 500V AC with a powerful 40KA maximum discharge current, this 2-pole surge arrester delivers industrial-strength defense against lightning strikes, switching transients, and overvoltage events that can damage sensitive electrical and electronic equipment.
Whether you’re protecting a residential home, commercial facility, or industrial plant, the Suntree 2P 500VAC 40KA SPD is the trusted choice of electricians, contractors, and system integrators across the world.
Key Features
- Voltage Rating: 500V AC — compatible with single-phase and three-phase AC systems

- Nominal Discharge Current (In): 20KA continuous surge handling capability
- 2-Pole (2P) Design: Simultaneous protection on both live and neutral conductors
- Type 2 SPD Compliance: Meets IEC 61643-11 for secondary surge protection
- DIN Rail Mounting: Easy snap-on installation on standard 35mm DIN rails
- Thermal Disconnect Protection: Automatically disconnects during thermal overload to prevent fire hazards
- LED Status Indicator: Clear green/red visual display for instant health monitoring
- Low Voltage Protection Level (Up): ≤1.5kV to protect sensitive downstream equipment
- Wide Operating Temperature: Performs reliably from -40°C to +80°C
Why Choose the Suntree 2P 500VAC 40KA SPD?
Every AC electrical system is exposed to damaging transient surges — from nearby lightning strikes, utility grid switching, and inductive load changes from motors and HVAC equipment. Left unprotected, these surges silently degrade or instantly destroy switchgear, inverters, PLCs, CCTV systems, UPS units, and other valuable equipment.
The Suntree 2P AC Surge Protector is built to intercept these events in less than 25 nanoseconds, safely channeling surge energy to ground before it reaches your equipment. With a 500VAC rating, it covers a wide range of single-phase AC applications while providing a substantial safety margin above the standard 230V/240V grid voltage.
Its compact 2-pole DIN rail form factor makes it ideal for installation in distribution boards, main DB panels, and sub-distribution boards — fitting seamlessly into both new installations and retrofit upgrades.
Applications
- Residential and commercial main distribution boards (DB panels)
- Office buildings and retail shop electrical panels
- Industrial control panels and motor control centers (MCCs)
- UPS and backup power systems
- CCTV, alarm, and security system power supplies
- Telecom and data center AC power distribution
- Generator output surge protection
- Hotels, hospitals, and institutional electrical systems
- Solar inverter AC output protection
