THKMA836800 - 800Amp Circuit Breaker

THKMA836800 - 800 Amp Circuit Breaker

The THKMA836800 is an 800-amp, 3-pole molded-case circuit breaker designed for use in your commercial and industrial power distribution systems. Built on the THKM8 frame platform, this breaker features an interchangeable thermal magnetic trip unit that protects against overloads and short circuits. The internal common trip mechanism helps you to ensure that all poles open together when a fault occurs.

With interrupting ratings of 25kA at 600VAC, 35kA at 480VAC, and 65kA at 240VAC, the THKMA836800 is suitable for a wide range of electrical distribution applications. Its bolt-on construction provides a secure installation, while the included load-side lugs help simplify field wiring. Whether being installed in existing equipment or used as a direct replacement in a compatible system, this breaker is designed to provide the form, fit, and function required for demanding electrical environments.
