GE 400VAC - 40A, 400VAC, 2-Pole, Miniature Circuit Breaker (MCB)

Meet the GE 400VAC 40A 2-Pole Miniature Circuit Breaker (MCB) — a compact, high-reliability overcurrent protector designed for modern electrical systems. With a 40A current rating and a 400VAC maximum, this GE MCB delivers precise, dependable protection for your critical circuits.

Key specs at a glance

• Current rating: 40 A
• Voltage rating: up to 400 VAC
• Poles: 2-Pole
• Breaker type: Miniature Circuit Breaker (MCB)

Why a two-pole design matters

The 2-pole configuration ensures both live conductors trip together on fault. This provides safer isolation, simpler wiring in distribution panels, and improved protection for interconnected circuits in panelboards, switchboards, and control panels. For equipment that relies on paired conductors, a two-pole MCB minimizes the risk of single-line faults and partial power loss.

Ideal applications

• Industrial and commercial distribution panels where reliable phase protection is essential
• Motor control centers and machine control panels needing robust overcurrent protection
• OEM equipment enclosures that require compact, dependable circuit protection

What problems it solves

• Prevents electrical overloads from damaging wiring and equipment
• Enables quick, safe disconnection of both conductors to isolate faults
• Supports streamlined maintenance and safer troubleshooting in complex electrical enclosures

Practical use and tips

• Install in appropriate GE-compatible panelboard configurations to protect feeders and control circuits operating up to 400 VAC
• Verify the circuit current draw remains within the 40 A rating to minimize nuisance trips
• When a trip occurs, inspect for overcurrent conditions or wiring faults downstream and replace the MCB if the fault is cleared

engineered for dependable overcurrent protection in distribution panels and motor control centers, the GE 400VAC 40A 2-Pole MCB delivers clear, decisive protection where it matters most. Choose this GE MCB for robust safety, straightforward deployment, and reliable performance in industrial, commercial, and OEM electrical systems.
