ABB A2N200TW2U AC Contactor

ABB A2N200TW2U is a 2-pole molded-case circuit breaker (MCCB) rated for 200 A with a 240 V AC operating voltage and a 250 V DC withstand rating. The A2N200TW2U employs a fixed-trip mechanism, providing reliable overcurrent protection without user-adjustable trip settings, and it carries a 25 kA interrupting capacity at 240 VAC, enabling rapid disconnection under fault conditions. As part of ABB’s A2N family, this model is designed for low-voltage distribution applications where compact two-pole protection is needed for medium-sized circuits. Its 200 A continuous current rating pairs with a standard MCCB form factor suitable for installation in control panels, switchboards, and distribution enclosures, delivering protection against both overloads and short circuits. With a versatile voltage range and a robust interrupting capacity, the A2N200TW2U supports reliable, code-compliant protection for commercial and light industrial electrical installations that require dependable safeguarding of 200 A loads.
