The Schneider Electric Merlin Gerin MG29711 is a 3-pole molded case circuit breaker designed for robust electrical protection in demanding industrial and commercial environments. This breaker is part of the Merlin Gerin product family, known for its reliability in power distribution and motor control applications. It provides essential overcurrent and short-circuit protection for circuits operating at higher voltage levels.

Technical details

• Series: Merlin Gerin
• Poles: 3
• Current Rating: 80 Amperes (A)
• Voltage Rating: 690 Volts (V) AC
• Interrupting Capacity: To be verified against manufacturer datasheet. This specification is critical for ensuring the breaker can safely interrupt fault currents.
• Trip Unit Type: Thermal-magnetic. This indicates the breaker utilizes both a bimetallic strip for overload protection and an electromagnet for instantaneous short-circuit protection.
• Frame Size: To be verified against manufacturer datasheet. Frame size often dictates the physical dimensions and maximum current rating of the breaker.
• Terminal Type: To be verified against manufacturer datasheet. Common terminal types include screw, lug, or box lugs, which affect installation and conductor compatibility.

Applications & compatibility

This 690V circuit breaker is suitable for use in main distribution panels, motor control centers, and as feeder protection in heavy industrial settings. It is commonly found protecting equipment in manufacturing plants, power generation facilities, and large commercial buildings where higher voltage systems are employed. Compatibility with specific switchgear and panelboard systems should be confirmed with the manufacturer's documentation.
