Supco SMR610 Manual Reset High Pressure Switch, 610 PSI Cut-Out, R410A, SPST

Description

The Supco SMR610 is a high-quality Manual Reset (MR) High Pressure Switch engineered for R410A refrigerant applications. Designed to open on pressure rise, this SPST switch provides reliable high-side pressure protection for residential and commercial HVAC and refrigeration systems. When system pressure reaches the 610 PSI cut-out threshold, the switch opens the circuit and requires a manual reset before the system can resume operation — a critical safety feature that prevents repeated compressor cycling under fault conditions.

Key Features

• 610 PSI cut-out (open) set point for R410A high-side protection
• Manual Reset (MR) design requires technician intervention before restart
• Opens on pressure rise — protects compressor and system components from over-pressure damage
• SPST (Single Pole, Single Throw) switching configuration
• Optimized for R410A refrigerant applications
• Durable construction suitable for demanding HVAC and refrigeration environments

Application

The SMR610 is ideal for use in split systems, package units, heat pumps, and commercial refrigeration equipment operating with R410A refrigerant. The manual reset function ensures that a qualified technician must diagnose and resolve the root cause of a high-pressure fault before the system is allowed to restart, reducing the risk of repeated compressor damage.
