Federal Pioneer MQS71136S – 100A/100A, 600V, 3-Pole Twin Fusible Meter Switch – MQS7 Series

The Federal Pioneer MQS71136S redefines service-entrance reliability by pairing dual 100A fusible protection with integrated metering in a compact, rugged package. Designed for commercial and industrial power distribution, this 3-pole twin fusible meter switch delivers dependable overcurrent protection while giving you real-time visibility into load conditions. If you’re upgrading a switchgear enclosure or adding a dedicated metering point, the MQS71136S combines two circuits in one sturdy unit for streamlined control and energy monitoring.

Key advantages at a glance

• Twin 100A/100A fusible switches housed in a single enclosure, enabling dual-circuit protection without needing a second device.
• 600V AC, 3-pole design built for robust commercial and industrial power distribution.
• Integrated metering capability delivers accurate load monitoring directly through the switch, simplifying energy management and reporting.
• Compact, space-saving footprint ideal for retrofit projects or panel upgrades where space is at a premium.
• Rugged, utility-grade construction engineered for long-term service life in demanding environments and compliant with industry requirements.

Why this matters in real-world setups

In facilities where two feeders must be monitored and protected, the MQS71136S eliminates the need for two separate devices. This not only trims the panel footprint and installation complexity but also improves reliability by consolidating metering and isolation in a single, easy-to-service unit. The integrated metering capability provides timely load data, enabling smarter energy management, demand forecasting, and faster fault isolation during outages or maintenance.

Ideal applications

• Service entrances and distribution panels in commercial buildings, industrial plants, and campus facilities
• Utility and energy-management installations that require dual-circuit protection with built-in metering
• Upgrades where space is limited but dual-circuit control and metering are essential

What sets it apart from simple disconnects

While a basic switch isolates a circuit, the MQS71136S integrates dual protection with metering in a single enclosure, delivering both safety and visibility. This means faster commissioning, easier maintenance, and clearer energy data, all without compromising protective performance.
