Argo ARM-3P Zone Switching Relay

Argo ARM-3P Zone Switching Relay is a compact, electronic-actuated three-zone relay designed for expandable zone control. The Zone Switching Relay provides independent SPST switching for each zone, making it ideal for HVAC and multi-zone applications, while meeting CSA (Canada and US) and NEC safety standards.

Operating from a transformer rated for 120 V AC at 60 Hz with a 30 VA capacity, this relay supports a motor load up to 1/3 HP and a thermostat current of 0.085 A, delivering reliable performance in residential and light commercial systems.

• Type 3-Zone, Expandable: start with three zones and easily expand to meet growing control needs.
• Electronic actuation: precise, quiet switching for consistent zone management.
• SPST switch type: simple wiring and compatibility with standard control circuits.
• CSA and NEC compliant: designed for safe North American installation.
• 120 V AC / 60 Hz, 30 VA transformer rating: robust power for typical zone-control loads.
• 1/3 HP motor support and 0.085 A thermostat current: suitable for common heating and control applications.
