Rectorseal M19002 Mars 63 Relay

Product Description

The RECTORSEAL M19002 is the MARS 63 relay, a switching component used in HVAC and plumbing-related control circuits. Relays of this type open and close electrical circuits in response to a control signal, allowing low-voltage thermostat or control board outputs to switch higher-load equipment such as motors, pumps, or compressors. Licensed HVAC technicians and plumbers working on hydronic, refrigeration, or general HVAC systems are the primary installers of this component.

The MARS 63 relay is suited for residential and light commercial applications where a reliable switching device is needed in a control circuit. It is commonly installed as part of an HVAC system control sequence, a hydronic heating circuit, or a similar mechanical system requiring relay-based switching. This relay is appropriate for new installations as well as direct replacement of failed or degraded relay components in existing systems.

Key Features

• Relay configuration suitable for HVAC and plumbing control circuit applications
• Designed for use as a replacement or new-installation switching component
• Compatible with standard control board and thermostat output signals
• Compact form factor typical of MARS-series relay products

Compatibility

Designed as an OEM-style replacement relay for HVAC and plumbing control circuit applications where a MARS 63 relay is specified.

Installation Notes

A licensed HVAC technician or qualified plumber should install this relay. Shut off all power to the system at the disconnect or breaker before removing the existing relay or making any wiring connections. Verify that the replacement relay matches the voltage and current ratings required by the circuit before energizing. Follow applicable NEC guidelines for low-voltage and line-voltage control wiring.
