QMQB1132 - 100A, 240V, 3-Pole, Fused Disconnect Switch

The QMQB1132 is a rugged, three-pole fused disconnect switch built for industrial and commercial environments that demand safe electrical isolation and dependable performance. With a 100A rating at 240V, it provides a clear, definitive disconnection point for three-phase power while combining fuse protection to guard against faults and overloads. Designed to support lockout/tagout procedures, this switch helps keep maintenance teams safe during service and prevents unexpected energy release.

Key Features

• 100A amperage rating paired with 240V operation for standard three-phase systems
• 3-Pole configuration ensures all three phases are safely isolated simultaneously
• Built-in fuse protection delivers reliable interrupting capability under fault or overload conditions
• Lockout/tagout-ready design supports safe maintenance practices and energy control
• Engineered for long-term durability in demanding industrial environments

Specifications

• Amperage Rating: 100A
• Voltage Rating: 240V
• Number of Poles: 3-Pole
• Product Type: Fused Disconnect Switch
• Model: QMQB1132

Ideal Use Scenarios

The QMQB1132 is purpose-built for applications where reliable electrical isolation and protection are essential. It’s an ideal fit for:

• Motor control circuits in manufacturing lines, conveyors, and processing equipment
• HVAC and chilled–water systems where safe power isolation during maintenance is critical
• Pumps, compressors, and other three-phase equipment that require dependable shutdown under fault conditions
• Control panels and equipment rooms that rely on stringent lockout/tagout procedures for worker safety

Why This Fused Disconnect Stands Out

Compared to non-fused disconnects, the QMQB1132 combines immediate disconnection with built-in protective fusing, enabling faster fault clearance and enhanced circuit protection. The three-pole design guarantees coordinated isolation of all phases, reducing arc exposure and improving maintenance safety. Its durable construction is tailored for long service life in environments where reliability matters as much as safety.

Practical Tips for Maximizing Safety and Performance

• Pair the QMQB1132 with compatible fuses and follow lockout/tagout procedures to secure equipment during servicing
• Install in a suitably accessible control area so maintenance staff can operate the switch without bypassing safety protocols
• Verify system compatibility: ensure your three-phase 240V infrastructure aligns with the 100A rating to prevent nuisance trips
• Document the disconnect location in your electrical drawings and safety manuals to streamline future maintenance and audits

The QMQB1132 delivers a precise blend of safety, reliability, and practical protection for everyday industrial power control. Its 3-pole, fused design provides robust isolation for critical equipment, empowering your team to work confidently and efficiently.
