This GE MCCB provides overcurrent protection for electrical feeders and distribution panels, allowing automatic interruption of fault currents to safeguard conductors and equipment. The three‑pole design supports three‑phase systems, and the 600 V rating defines the maximum system voltage for safe operation. As part of GE's molded‑case breaker lineup, the TKM436F000 is designed for integration into standard enclosures within a coordinated protection scheme that uses a defined trip threshold. When installed, it trips at 300 A to isolate protected circuits during overload or short‑circuit conditions, and it is suitable for use in industrial and commercial power distribution where reliable protection of feeders and equipment is required.\u003c\/p\u003e\u003c\/div\u003e","brand":"GE","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46284423692522,"sku":null,"price":283.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-055.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/ge-circuit-breaker-tkm436f000-400-amps-600-volt-3-pole-w-300-amp-trip-unit","provider":"GTG Hardware","version":"1.0","type":"link"}
