Miniature 100AMP - 100A, 2-Pole, Miniature Circuit Breaker (MCB)

Meet the Miniature 100AMP - 100A, 2-Pole, Miniature Circuit Breaker (MCB) — a compact, rugged overcurrent protector built for crowded electrical spaces where reliability matters most.

With a 100A rating and a 2-Pole configuration, this MCB interrupts both conductors in a circuit, delivering safe, instant isolation when current spikes occur in panelboards, switchboards, and control panels. It’s designed for continuous service in demanding environments across industrial, commercial, and OEM applications.

Why this 2-Pole MCB stands out

• Precise overcurrent protection at 100A, ensuring equipment like motors, transformers, and feeders stay within safe limits.
• Two-pole design for simultaneous disconnection of both conductors, simplifying wiring and improving safety in multi-wire circuits.
• Compact footprint fits densely packed panels and retrofit projects without sacrificing protection.
• Versatile mounting suitable for panelboards, switchboards, and control enclosures commonly found in industrial and commercial settings.
• OEM-friendly ready for original equipment manufacturing where dependable, repeatable protection is essential.

This MCB is ideal for panel builders and maintenance teams who need predictable performance in motor control centers, distribution panels, and automation cabinets. It provides a straightforward, resettable protection option that minimizes downtime and simplifies spare-part inventories compared with fuse-based solutions.

Practical guidance for deployment

• Verify compatibility with your panel’s enclosure and labeling; confirm the breaker’s current rating meets your circuit’s requirements.
• Install in accordance with local electrical codes and the device’s datasheet, using proper torque and termination practices to ensure reliable connections.
• Use this 2-Pole MCB in pairs or with other protection devices to achieve the desired selective protection strategy for your distribution network.
