Low-voltage electrical systems are the backbone of modern facilities. From motor control centers and switchgear to PDUs and panelboards, these systems power production lines, data centers, water treatment plants, and critical infrastructure.
And while they may operate at or below 600V, the risk of thermal failure is very real.
The GraceSense HSM 600 was engineered specifically for these environments — delivering Continuous Thermal Monitoring (CTM) across low-voltage electrical equipment to detect developing hot spots before they become downtime events.
Low-voltage systems are often perceived as “lower risk” compared to medium- or high-voltage gear. But in reality, many failures originate in these systems due to:
Thermal events rarely happen suddenly.
They develop gradually — temperature rising above trend, connection resistance increasing, insulation degrading over time.
By the time infrared scans detect the issue, the problem may already be advanced.
The HSM-600 is designed for electrical equipment operating at or below 600 VAC, making it ideal for:
Unlike portable thermography, the HSM-600 provides continuous visibility — not just a snapshot in time.
This is especially important as NFPA 70B standards increasingly emphasize documented maintenance and equipment condition as part of a risk assessment process.
The HSM 600 architecture is built around a distributed monitoring approach:
This design allows facilities to monitor multiple termination points within a single cabinet, providing early indication of abnormal temperature rise.
Instead of relying solely on annual or quarterly IR inspections, facilities can monitor trends continuously and act before a failure escalates.
Infrared inspections remain valuable — but they represent a moment in time.
Continuous Thermal Monitoring (CTM) complements IR by:
For facilities seeking to reduce downtime and support proactive maintenance programs, continuous monitoring closes the visibility gap.
Low-voltage equipment environments are demanding. The HSM 600 is designed to integrate cleanly inside existing cabinets and operate reliably within industrial settings.
Key benefits include:
This makes it well suited for manufacturing plants, commercial buildings, utilities, and especially data center electrical distribution systems where uptime is critical.
As maintenance standards evolve, documenting equipment condition and demonstrating that equipment is operating under normal conditions becomes increasingly important.
Continuous Thermal Monitoring can play a role in:
For organizations focused on strengthening electrical safety and reliability programs, monitoring low-voltage equipment continuously provides another layer of protection.
The GraceSense Hot Spot Monitor 600 (HSM 600) provides continuous thermal monitoring (CTM) for systems up to 600V.
By installing powered thermistor-based sensors at critical connection points, the system continuously monitors temperature behavior and compares it against ambient conditions. When abnormal heat rise is detected, the system provides clear indication so teams can investigate early.
The objective is straightforward: detect developing conditions sooner and support more informed maintenance decisions.
The HSM 600 supports modern condition-based maintenance strategies by providing:
Because the system is always monitoring, it helps address the visibility gap left by periodic inspections.
