Rectorseal M19164 Mars 164 Relay

Product Description

The RECTORSEAL M19164 is the MARS 164 relay, a control relay designed for use in HVAC and plumbing system control circuits. Relays of this type switch load circuits on and off in response to a low-voltage control signal, allowing thermostats, controllers, or other switching devices to operate higher-current loads without direct contact. Licensed HVAC technicians and plumbers install units like this as part of control system assemblies, zone valve wiring, or auxiliary switching applications. The compact housing measures 2.0 inches in length, 1.85 inches in height, and 1.69 inches in depth, making it suitable for installations where panel space is limited.

The MARS 164 relay is intended for residential and light commercial HVAC and plumbing control applications. It fits into control panels, zone control boards, and auxiliary switching setups where a reliable switching relay is required. Its compact footprint allows installation in tight enclosures or alongside other control components without requiring significant additional space.

Key Features

• Compact form factor at 2.0 x 1.85 x 1.69 inches for space-limited installations
• Designed for use in low-voltage HVAC and plumbing control circuits
