200 A, 2-pole MCCB — what it covers
The A2A200TW-2 is a 2-pole molded case circuit breaker rated at 200 A, with a fixed thermal-magnetic trip mechanism. It is listed for 240 VAC and 250 VDC applications — the DC rating makes it a candidate for battery banks, UPS distribution, or DC bus protection where a standard AC-only MCCB would not clear a fault.
Trip curve and deployment context
The thermal-magnetic trip device provides inverse-time overload protection (thermal element) plus instantaneous short-circuit response (magnetic element). The fixed trip point means no field-adjustable rating plug — the 200 A frame is the circuit's hard limit. In a panel, the 2-pole footprint occupies a standard MCCB mounting slot; the DC rating extends its use beyond typical AC branch circuits into DC distribution where a standard AC breaker may not have a listed interrupting rating.
