YUKGAMS HVAC Surge Protector AG3000 120/240V

The YUKGAMS AG3000 is a dedicated 120/240V surge protector built to shield mini-splits and HVAC systems with TPMOV technology inside a Type 4X watertight enclosure.

Power surges from storms, utility switching or nearby lightning strikes can damage outdoor compressors and indoor control boards. The AG3000 combines thermally protected metal-oxide varistors (TPMOV), multi-mode surge suppression and a UV-resistant, watertight housing so you can install robust protection at the service point or right at the outdoor unit.

How does the AG3000 protect split-system air conditioners and HVAC equipment?

The AG3000 diverts harmful voltage spikes across three protection modes — line-to-ground, line-to-line and line-to-neutral — minimizing the energy that reaches sensitive components. TPMOVs provide over-voltage clamping while thermal protection reduces failure risk common to traditional MOVs.

• Three-mode protection: L-G, L-L and L-N for comprehensive coverage
• TPMOV elements that clamp surges then disconnect when overheated
• Reduces the chance of board, sensor or compressor damage

Where can I mount the AG3000 and how weatherproof is it?

The unit is housed in a Type 4X UV-resistant plastic enclosure designed for outdoor or indoor mounting. The watertight design allows placement close to outdoor condensers, disconnect boxes or inline at service panels without worrying about rain or direct sunlight.

• Type 4X rating for corrosion and water resistance
• UV-stable plastic resists long-term sun exposure
• Compact footprint fits near condensers or inside disconnect enclosures

How do I know the AG3000 is still working?

An integrated green LED provides a fast visual check of protection status so installers and homeowners can confirm operation at a glance. The LED lets you monitor whether the suppression circuitry remains active without opening the enclosure.

• Built-in green LED status indicator for immediate verification
• No special tools required to check protection health
• Reduces unnecessary troubleshooting visits by showing status clearly

What makes TPMOV different from standard MOVs and why does it matter?

TPMOVs include an internal thermal disconnect that isolates the varistor if it overheats or sustains a damaging surge. This added safety lowers failure risk and improves longevity compared with unprotected MOV-only designs.

• Thermal disconnect improves safety during extreme surge events
• Extends component life and reduces replacement frequency
• Designed for reliable operation across repeated transient events

Who is this for: The YUKGAMS AG3000 is intended for HVAC technicians, contractors and homeowners who need point-of-use surge protection for mini-splits, outdoor condensers and indoor control circuits. It’s a good choice when you want a compact, weatherproof device that gives visible status feedback, utilizes TPMOV safety features and is simple to mount near the equipment being protected. Each unit is tested before shipment and backed by six years of support to help ensure long-term operation and serviceability.
