Square D LAP36200MT Molded Case Circuit Breaker

This unit-mount, bolt-on MCCB is engineered for use in Square D switchboards, motor control centers, and industrial control panels. Because it is a bolt-on device, it is not compatible with plug-on I-Line panelboards.

The LAP36200MT features a thermal-magnetic trip unit with a fixed thermal element for overload protection and an adjustable magnetic element for short-circuit protection. The adjustable dial allows licensed electricians to coordinate the breaker's short-circuit response with other protective devices in the system and the specific inrush characteristics of the load.

The LAP36200MT is a legacy L-Frame breaker. For new installations or complete upgrades, Schneider Electric has replaced this series with the modern PowerPacT L-Frame circuit breakers. Upgrading an existing legacy installation to a PowerPacT model typically requires a specific retrofit kit to match the mounting and bus connections.

The breaker accepts both aluminum (Al) and copper (Cu) conductors. The lugs are designed to accommodate either a single wire ranging from 1 AWG to 600 kcmil, or dual wires ranging from 1 AWG to 250 kcmil per phase. Always apply the manufacturer specified torque when terminating connections.

Yes, the LAP36200MT belongs to the same legacy L-Frame family as the LAL36200 and shares the same physical dimensions and 200A, 600VAC ratings. However, the P and MT designations indicate differences in factory-installed lug configurations or mounting hardware. You may need to reuse your existing lugs or mounting brackets when swapping these models.

Yes, in addition to its AC ratings, this thermal-magnetic breaker is rated for use in DC electrical systems up to 250VDC, where it provides an interrupting capacity of 10kA.

Like most Square D molded case circuit breakers, this unit includes a push-to-trip feature. Electricians can use this button during routine maintenance to manually trip the breaker, ensuring the internal mechanical linkages are functioning correctly and preventing the mechanism from binding over time.

Yes, Square D legacy L-Frame breakers can be equipped with various internal accessories, such as shunt trips, auxiliary switches, and undervoltage releases. These accessories are typically used for remote tripping, status signaling, or integration into automated control systems.

The LAP36200MT features a visual trip indicator. When the breaker trips due to an overcurrent or short-circuit event, the handle moves to a center tripped position, allowing operators to quickly identify the faulted circuit in a crowded panel.
