MARSTEK Automatic Transfer Switch, True 2-Pole Isolation ATS
MARSTEK Automatic Transfer Switch, True 2-Pole Isolation ATS 63A (120) True 2-Pole Isolation，Output Timer for Solar/RV，Custom Safety Thresholds，Low-Heat Latching Relays，Auto & Manual Override
- TRUE 2-POLE PHYSICAL ISOLATION: Unlike standard switches, our upgraded 4-relay architecture simultaneously disconnects BOTH Live and Neutral wires. This creates a 100% physical barrier to prevent dangerous grid backfeeding and stops GFCI/AFCI breaker trips.
- BUILT-IN SMART OUTPUT TIMER: Save space and money without buying external timer relays. Easily program customized countdowns to cut or restore output power. Perfect for off-grid battery management, timed agricultural irrigation, or RV scheduled lighting.
- FULLY PROGRAMMABLE PROTECTION: Features an advanced digital panel to set custom thresholds for Overvoltage, Undervoltage, and Overcurrent. It continuously monitors your circuit and automatically safely locks out after repeated severe faults.
- LOW-HEAT MAGNETIC LATCHING: Engineered for high-efficiency and enclosed breaker panels. The magnetic latching relays only require a millisecond pulse to switch, meaning they generate significantly less heat and last much longer than traditional relays.
- AUTO & MANUAL SEAMLESS SWITCHING: Freely select Source 1 or Source 2 as your priority without rewiring. Features manual override buttons to instantly force a power toggle, ensuring you always have full control over your home, RV, or solar backup system.
