Square D MJL36350 - 350 A, 600 V, 3-Pole Circuit Breaker | AmpState

Upgrade your electrical protection with the Square D MJL36350 — a 350 A, 600 V, 3-pole molded case circuit breaker designed for dependable branch circuit overcurrent and short-circuit protection. Engineered to integrate seamlessly with OEM panelboards and load centers, this breaker delivers reliable performance where space is at a premium and protection is non-negotiable.

Overview

The MJL36350 combines a compact molded case design with a thermal-magnetic trip unit, delivering stable, repeatable protection for demanding electrical installations. Its 3-pole construction is ideal for balanced 3-phase systems, making it a practical choice for residential add-ons, commercial upgrades, and light industrial applications.

Key Features

• Compact molded case design maximizes panel space and simplifies layout in tight panelboards and load centers.
• Thermal-magnetic trip unit provides precise protection against both overloads and short circuits with repeatable trip performance.
• 3-pole configuration supports three-phase protection for balanced systems and feeders.
• OEM-compatible ensures reliable fit and performance with matching brand load centers and panelboards.
• Versatile applications suitable for residential, commercial, and light industrial installations.

Technical Specifications

• Manufacturer: Square D
• Part Number: MJL36350
• Type: Thermal-magnetic molded case circuit breaker
• Amperage Rating: 350 A
• Voltage Rating: 600 V
• Number of Poles: 3
• Application: Branch circuit overcurrent and short-circuit protection

Ideal Use Scenarios

• Upgrading service panels or adding circuits in residential basements, attics, or garages where space efficiency matters.
• Commercial panelboards and small-to-mid size electrical rooms needing reliable 3-phase protection.
• Light industrial equipment feeders where robust protection and quick, repeatable trips are critical.

Why This Model Stands Out

Unlike bulky alternatives, the MJL36350 delivers high-current protection in a compact form, helping you maximize panel density without compromising safety. The thermal-magnetic trip unit ensures protection is accurate and dependable across varying loads and fault conditions, reducing nuisance trips and potential equipment damage. Its OEM compatibility means fewer headaches during installation or replacement, preserving panel integrity and performance.

Installation & Compatibility Tips

• Verify the panelboard or load center is designed to accept 3-pole molded case breakers and is compatible with the MJL series from Square D.
• Confirm the voltage rating (600 V) aligns with your system requirements and that the 350 A amperage rating suits your load profile.
• Use the MJL36350 specifically for branch circuit protection to ensure proper coordination with upstream protective devices.

For installations that demand dependable protection with efficient panel usage, the Square D MJL36350 350 A, 600 V, 3-Pole Molded Case Circuit Breaker is a well-balanced choice. Add it to your panel today and reinforce your electrical system with trusted Square D protection.
