The RSH-50 Series safeguards HVAC equipment from electrical surges, handling up to 50,000-amp single surges and 10,000-amp repetitive surges. As a Type 1 Device, it's versatile, allowing mounting anywhere in the electrical system for effective protection.

The RSH-60 Series protects HVAC equipment from electrical surges, brownouts, and short cycling with capabilities of up to 60,000-amp single surges and 20,000-amp repetitive surges. As a Type 1 Device, it's versatile, mountable in any position within the electrical system, ensuring robust defense for HVAC systems.

The RSH Voltage Range Monitoring (VRM) devices protect equipment from damage by overseeing voltage levels, with programmable cutoff ranges from 90V to 300V. They can also store data on up to 300 events, providing a comprehensive record for analysis and response. The RSH-50 VRMDC KIT model combines the VRM60A, RSH-50, & 60A disconnect breaker in a NEMA 3R enclosure, for an all-in-one equipment solution.

Install RSH-120 at the breaker box for whole-home protection against transient power surges, preventing malfunctions and equipment degradation. With a capacity for up to 120,000-amp single surges and 20,000-amp repetitive surges, it is a versatile Type 1 Device that can be mounted in any position for effective safeguarding.

RSH-20 motor protectors shield ECM indoor motors from transient over-voltages and surges, enhancing motor durability and performance against electrical disturbances. Handling up to 20,000-amp single surges and 5,000-amp repetitive surges, these Type 4CA devices are mounted between the motor and power harness.
