Sentinel Series RPP

Remote Power Panels engineered for mission-critical loads

The Sentinel Series RPP delivers branch-circuit distribution, true-RMS monitoring, and field-proven components in a single UL-listed enclosure. Three frame sizes, three mounting configurations, and a 4-week lead time from stock.

The Product Line

One platform, three frame sizes

Every Sentinel Series RPP shares the same enclosure footprint, monitoring architecture, and component set — so you specify the amperage your white-space needs and standardize the rest. Each model supports up to 84 single-pole branch-circuit positions, with branch breakers from 20A to 150A and optional 30A/3-pole and 50A/3-pole configurations.

SN-225 — 225A main, compact distribution for edge and telecom rooms
SN-400 — 400A main, the workhorse frame for white-space rows
SN-600 — 600A main, 100% rated LSI main breaker for high-density halls

Select a Frame

SN-225 / SN-400 / SN-600

Common architecture across the line means a single submittal package, a single spare-parts kit, and a predictable install.

SN-225

225A Frame

Compact main rating for telecom closets, edge deployments, and lower-density rooms. Full 84-position branch capacity and InSight BCMS in a standard 24in x 12in x 90in enclosure.

SN-400

400A Frame

The most-specified frame for data center white-space. Balances branch density and main capacity for typical per-row distribution requirements.

SN-600

600A Frame

Maximum main input up to 600A with a 100% rated LSI main breaker for high-density compute, crypto, and consolidated distribution.

InSight BCMS

Branch-circuit monitoring, built in

InSight BCMS is integrated into every Sentinel Series RPP — not bolted on. A local touchscreen and DIN-rail modular metering deliver +/-0.5% true-RMS measurement of current, voltage, energy, and power quality at the panel and at every branch. The architecture is scalable, and the doors stay closed during readings.

+/-0.5% true-RMS current, voltage, energy, and power-quality metering
Local touchscreen interface with branch-level visibility
DIN-rail modular and scalable to the position count you deploy
Closed-door operation — no exposure to live parts to read data

Why Specify Sentinel Series

Key advantages

⚑

Built to spec

Voltages, breaker schedule, entry, and monitoring scope are configured to your one-line — not forced into a fixed catalog SKU.

⏱

4-week delivery

Standard frames are in stock now with a 4-week lead time, so the RPP is not the long pole in your project schedule.

✓

UL listed

Indoor UL Type 1 enclosure, seismic tested, with 14 kAIC @ 480VAC SCCR standard and 65 kAIC optional.

⚙

Premium components

Siemens Approved OEM build with field-proven breakers and metering — the components your standards already call out.

▯

Scalable & configurable

Up to 84 single-pole branch positions, modular InSight metering, and three mounting configurations from one platform.

☎

Engineering support

Direct access to engineers for submittal review, breaker scheduling, and configuration before you release the order.

Mounting Configurations

Free-standing, wall-mounted, or back-to-back

The Sentinel Series RPP fits the floor plan you have. Specify free-standing for open rows, wall-mounted to reclaim aisle space, or back-to-back to double distribution density against a shared wall. Top and bottom cable entry support overhead bus and underfloor feeds, and optional IR inspection windows allow thermographic survey without opening the enclosure.

Free-standing, wall-mounted, and back-to-back configurations
Top & bottom cable entry for overhead or underfloor feeds
Optional IR inspection windows for closed-door thermography
Optional surge protection up to 100kA
