Murray MP115 - 15A, 1-Pole, Circuit Breaker

Murray MP115 - 15A, 1-Pole Circuit Breaker is a compact overcurrent protection device designed to safeguard a single branch circuit in your electrical distribution setup. With a 15-amp rating and a single pole, this breaker delivers reliable interruption of fault or overload currents to keep panelboards, switchboards, and control panels operating safely.

Where it shines

Built for industrial, commercial, and OEM environments where dependable protection and safe operation are critical, the MP115 fits into standard distribution panels and motor control centers. Its streamlined, space-conscious design helps you maximize panel capacity without compromising safety.

What makes it unique

• 15A current rating for targeted protection of smaller branch circuits, reducing nuisance trips on normal loads while stopping faults early.
• 1-Pole design provides single-phase protection for an individual circuit without unnecessary complexity.
• Versatile compatibility with panelboards, switchboards, and control panels, promoting flexible layouts and configurations.
• Industrial-grade reliability built to support continuous operation in distribution panels and motor control centers.

Practical use cases

• New installations in manufacturing lines requiring a dedicated 15A, single-circuit protector.
• Retrofitting older control panels that need a compact, 1-pole breaker to protect a single motor starter circuit or control loop.
• OEM equipment builds where space constraints demand a slim, single-pole protection solution.

Tips for installation and optimal performance

• Verify that your enclosure and bus assembly are compatible with a 1-Pole Murray MP115 unit and that the form factor matches the panel’s designated space.
• Always shut off power and follow your site’s lockout/tagout procedures before replacement or installation.
• Regularly inspect connections for tightness and corrosion to maintain reliable trip performance over time.
