The line-up

Three ratings, one platform

SN-225, SN-400, and SN-600 share an identical footprint, monitoring system, and feeder layout — so you size to the load, not the cabinet.

SN-225

225A

Compact branch distribution for high-density white space and edge deployments where feeder capacity is modest but circuit count is high.

SN-400

400A

The workhorse rating for most critical-facility deployments — the right balance of capacity and circuit density per row.

SN-600

600A

Maximum capacity in the same 24″ × 12″ × 90″ footprint, for the highest-density racks and busways.

Features & Benefits

Engineered for the white space

Every Sentinel Series panel is built to your single-line and breaker schedule on a platform proven in mission-critical facilities. The result is dense, monitored distribution that drops cleanly into the room with no surprises at commissioning.

Built to fit your room

Three mounting configurations

The same platform installs three ways, so the panel adapts to the floor plan instead of forcing a redesign.

◫

Free-Standing

The standard 24″ × 12″ × 90″ floor-mount cabinet, with full front access and top or bottom cable entry.

▤

Wall-Mounted

Space-saving install for the same electrical platform where floor space is at a premium along the perimeter.

◫◫

Back-to-Back

Maximum density — two panels sharing a common footprint to double circuit count in a single row position.

InSight BCMS

Branch-circuit visibility, built in

Every Sentinel Series panel ships with an integrated Branch Circuit Monitoring System and a local touchscreen — real-time current, voltage, energy, and power-quality data across main and branch circuits, at ±0.5% true-RMS accuracy. Metering modules are DIN-rail mounted, modular, and scalable, so you monitor only the circuits you need today and add coverage later without re-engineering the panel.

Integrated branch-circuit metering with local touchscreen
±0.5% true-RMS current, voltage, energy & power quality
DIN-rail modular hardware — scalable per circuit
