SEM3T Thermal Monitoring

Why SEM3T?

Get continuous, real-time visibility into thermal risk across low‑voltage equipment. SEM3T delivers safer monitoring than periodic IR scans, helps prevent unplanned outages, and installs easily with UL‑listed sensors and OSHA‑minded features. Recognized as a 2021 Product of the Year award winner by readers of Consulting-Specifying Engineer in the Electrical: fuses, circuit breakers and Safety category, SEM3T combines proven reliability with modular scalability—from a few points to entire switchboards and gear.

Key benefits

Cut downtime risk

Detect hotspots 24x7 at critical joints to act before failures, reducing costly outages in commercial and industrial applications.

Enhance operator safety

Measure actual connection temperatures without opening energized equipment, supporting safer maintenance practices than IR scans.

Simplify deployment and scaling

Start small then expand with modular modules and controllers to cover up to 45 thermal points per controller, daisy chained as needed.

Featured capabilities

Monitor critical points continuously

Permanent, non‑invasive sensing provides real‑time data, alarms, and trending via built‑in web pages for fast decision making.

Integrate with existing systems

Use standard Modbus TCP, dual Ethernet, optional Wi‑Fi, and MindSphere readiness to connect SEM3T to plant monitoring and analytics

Scale across low‑voltage apparatus

Apply sensors on bus joints, lug landings, bus ducts, transformers, and circuit breakers for comprehensive coverage.
