Altech 2B16UM - 16A, 277VAC / 80VDC, 2-Pole, Circuit Breaker

Meet the Altech 2B16UM, a purpose-built 2-pole circuit breaker engineered to deliver dependable overcurrent protection where it matters most. Rated for 16A and capable of handling up to 277VAC or 80VDC, this device is ready for both AC mains and DC control circuits in demanding industrial environments.

Designed for flexible integration, the 2B16UM shines in panelboards, switchboards, and control panels. The two-pole configuration ensures a coordinated disconnect on both conductors, promoting safer startup and shutdown sequences and helping keep your distribution system balanced and protected during fault conditions.

• Current and voltage versatility: 16A rating with a dual voltage capability of 277VAC / 80VDC supports mixed power architectures commonly found in modern facilities.
• Two-pole protection: Simultaneous disconnection of both lines minimizes arc risk and protects downstream equipment in motor control centers and control panels.
• Versatile installation domains: Ideal for industrial, commercial, and OEM applications where compact, reliable overcurrent protection is essential in distribution panels.
• Reliability you can trust: Built to provide safe operation in mission-critical panel assemblies, ensuring continuity of control circuits and power distribution.

Who should consider the Altech 2B16UM? System integrators, maintenance engineers, and OEM designers looking for a compact, dependable breaker that can navigate mixed-voltage systems without sacrificing protection quality. It’s a practical choice for modernizing existing panels or configuring new control enclosures where robust overcurrent protection is non-negotiable.

Practical tips for deployment:

• Pair the 2B16UM with panelboards or switchboards that service both AC distribution and DC control circuits to reduce component count and simplify wiring.
• Use in motor control centers where rapid, coordinated shutdown of paired conductors enhances safety and reduces downtime.
• Confirm system voltage alignment with 277VAC and DC control segments up to 80VDC to ensure optimal protection without nuisance trips.
