General Electric | MB113 | Circuit Breaker | 3-Pole | 240V

General Electric MB113 is a 3-pole, 240V circuit breaker designed to support maintenance, retrofit, and replacement projects where exact compatibility matters. Rely on the MB113 part number as your primary reference to ensure proper fit within GE-style panels and compatible equipment.

Key Details

• Poles: 3-Pole
• Voltage rating: 240V
• Part number: MB113
• Fit and compatibility: Confirm fit and ratings before ordering; the part number is the best reference for compatibility.

Why choose the MB113 for your electrical panel

This 3-pole, 240V circuit breaker is purpose-built for systems that require reliable multi-pole protection. It provides coordinated interruption across three conductors, helping to safeguard equipment and wiring from overcurrent conditions in three-phase or multi-wire configurations. By aligning with GE’s design standards, it supports predictable trip performance and straightforward replacement in panels that accept MB-series devices.

Ideal use cases

• Maintenance on GE-compatible panels that require a 3-pole, 240V protection device.
• Retrofit projects where existing equipment matches the MB113 form factor and rating.
• Replacement for failed or out-of-spec breakers in compatible GE systems, helping minimize downtime.

Practical guidance for installation and compatibility

Before ordering, verify that the MB113 matches your panel’s specifications and the overall system design. Use the part number MB113 as the primary reference to confirm compatibility with your GE panelboard or switchgear. Ensure the breaker’s voltage and pole configuration align with the circuit you intend to protect. For safe handling, disconnect power and follow standard electrical bonding and grounding practices during installation, or consult a qualified electrician if you’re unsure about the panel compatibility.

What problems this solves

With a dedicated 3-pole, 240V design, this GE circuit breaker provides reliable overcurrent protection across three conductors, helping prevent electrical fires and equipment damage in multi-phase electrical systems. It simplifies replacement workflows by offering a straightforward, part-number-driven path to restore protective capabilities when components wear out or ratings drift.
